2008 jeep patriot. Throttle body and traction control light are on and very low power
Like I said the throttle body light and traction control light are on. Vehicle has low power around 500 rpm when gas petal is floored. I changed the throttle body, a wire clip that goes to the throttle body. I also looked on forms which suggested checking the abs system and I found no problems. Lights still on still have low power. Any thoughts
My car has 124000 miles.
My car has an automatic transmission.

Hi There,
The throttle body light may come on when the throttle control motor is not working properly. The throttle control motor is what opens and closes the throttle blade inside the throttle body. This may also suggest you have a faulty throttle position sensor. The throttle position sensor monitors the throttle position of the throttle plate inside the throttle body in relation to your foot position on the gas pedal. Based upon the inputs from the sensor reading your foot’s position on the pedal, the ECU then makes the direction to supply more or less fuel to the motor. When this sensor is not working properly, this can cause intermittent responses when pressing the gas pedal.

The traction control system monitors the steering and stability of the vehicle and engages when loss of traction has been detected. This is done by the use of electronic sensors at each of the four wheels that communicate with the Powertrain Control Module (PCM) regarding steering performance and stability in adverse weather conditions. The traction control system works by reducing engine speed and determining which wheel to apply brake pressure to in order to prevent the vehicle from sliding. The anti-lock braking system and the traction control system work together to maintain the stability of the vehicle. The computer uses this information received from electronic sensors regarding the rotational speed of each wheel, the horizontal motion of the vehicle, and the vertical motion of the vehicle to determine how to direct the traction control system or the anti-lock braking system to best control the vehicle when needed. When this warning indicator light comes on in the dashboard, this could be an indication of several issues such as faulty wheel speed sensors, a faulty steering angle sensor, a faulty rotational speed sensor or a problem with the steering rack. In some cases, the traction control system may simply need to be reprogrammed. I would recommend having a professional from YourMechanic come to your location to properly diagnose your traction control system.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
Your Jeep Patriot traction control light will briefly illuminate when you are facing difficult road conditions, indicating the system is active. However, if the light remains on your dashboard for an extended time, you may have a malfunction on your hands.
Common symptoms
Throttle body and electronic throttle body issues can result in the engine stalling, failing to start, warning lights on the instrument cluster, and hesitation or power surging on acceleration.
What does it mean when the throttle control light comes on? Simply enough, when your throttle control warning light comes on, there is something wrong with the throttle system in your car, in other words, the system in your car that converts inputs from the gas pedal into power, delivered from the engine.
Generally speaking, low tire pressure can cause your car`s traction control light to come on. If one or more of your tires is low on air, it will allow the center of the tread to collapse – becoming concave and trapping water rather than flowing it through the tread design.
When the throttle body gets dirty, it has a direct effect on how smoothly the engine operates. Signs indicating a problem include rough idling, jumpy or sluggish acceleration, poor fuel economy, and stalling.
The throttle position sensor (also known as the TPS sensor or Throttle Valve Position sensor) is a part of the electronic throttle control system and is connected to the throttle body and monitors your vehicle`s throttle angle.
The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.
Set your multimeter to the 10 DC voltage range, place the black negative probe on the ground terminal of the TPS, and place the red positive probe on the reference voltage terminal of the TPS. If the meter does not read 5 volts, the TPS is bad.
Is it Safe to Drive with the TCS Light On? It is only safe to drive with the TCS light on if it appears when you are losing traction: it means the system is engaging. Driving without traction control can make your vehicle susceptible to spinning out and sliding around on the road.
Press the gas pedal 3 times in quick succession. Then, turn your engine on all the way and let it run for a minute. The TCS and ABS lights should reset and go away if there isn`t any underlying problem with your traction control system.
Common signs include the Traction Control System (TCS) Light coming on, TCS not turning off/on, and loss of TCS or ABS features.
The Traction Control Light on modern cars typically is illuminated when the driver of the car turns the system off. If you didn`t complete this step or if the traction control is active, the most common reason that the light is illuminated is due to a faulty wheel speed sensor.
Filth, carbon, and dirt can build up in the housing creating problems with air flow. Known as coking, the normally smooth service for air to travel becomes full of gunk and creates an imbalance. This interrupts that perfect mixture of air and fuel which can cause the butterfly valve to get stuck.
Cleaning fuel injectors is generally not a do-it-yourself project, but you can clean the throttle body on your vehicle with common tools and specialized spray cleaners. While throttle-body cleaning is good preventative car maintenance, it should also help engine drivability.
The throttle body plays a large role in controlling the fuel and air mixture in your engine. The proper mixture needs to be achieved in order for your engine to run smoothly and properly. Once this part fails, it needs replacing rather than repairing.
So a bad throttle position sensor may produce symptoms that are not only related to speed and transmission shifts but also corresponding to a disturbed fuel ratio. Generally, the way a bad throttle position sensor causes driveability issues is by intermittently misjudging the position of the throttle.
Among the two most important parts within the throttle body are the throttle body position sensor (TPS) and the throttle body temperature sensor. While they sound similar, they are indeed two individual parts that work together to efficiently mix fuel and air.
Over time, your engine`s throttle body collects debris that can make your engine idle rough and decrease fuel economy.
The Powertrain Control Module
The PCM will analyze the inputs from the APP, and then command the throttle body to act appropriately.
Press the gas pedal 3 times in quick succession. Then, turn your engine on all the way and let it run for a minute. The TCS and ABS lights should reset and go away if there isn`t any underlying problem with your traction control system.
The TPS is usually mounted on the throttle body (the housing that contains the throttle valve).
Press the gas pedal 3 times in quick succession. Then, turn your engine on all the way and let it run for a minute. The TCS and ABS lights should reset and go away if there isn`t any underlying problem with your traction control system.
If the traction control light won`t turn off, there can be some reasons. One reason could be that the fuse for the traction control system has blown. Or it could be that there is a problem with the traction control sensors causing the light to stay on.

on starting engine light & throttle control and traction control light comes on and car idols hard no codes when scanned
ANSWER : Hello, and thank you for writing in. Unfortunately the first technician is correct in that this can be cause by a wide variety of issues. Considering that it is intermittent, we can assume that there is either an electrical issue (sensor or bad connection), or that there is a particular part which is dirty or failing. There are a couple of ways you can approach this. One being that you attempt to clean, repair, and replace the many number of components that can cause this. A second being that you attempt to replicate the issue by unplugging sensors and trying various tests to try and narrow down what system is being effected. When dealing with a misfiring situation, you need to look into the air intake, ignition (spark), and the fuel systems first. One last consideration is to have the vehicle scanned by another type of code reader. They vary in brand, manufacture compatibility, and software.

2012 equinox reduced power light engine light and traction light came on. Lost a lot of power got home and all light except engine
ANSWER : Your car has what is called a "safe mode" that will be engaged by the computer when it detects that something critical has gone wrong related to any of the major components in your engine chassis or power train. This may be related to a number of things, most of which should have been registered in the computer when the check engine light came on. I recommend having an expert from YourMechanic come to your location to inspect your check engine light and diagnose any codes registered by your vehicle’s computer.
Abs light, emergency brake light, steering wheel assist light, engine light, EPC light, traction control light
ANSWER : Hello, thank you for writing in. The vehicle does utilize a lot of the same sensors for these systems. Are there any other codes that are coming up when this code appears? If so you will want to take these into consideration when processing the repair and making a diagnosis. The module may be bad, and replacing it should fix the problem. The lights should turn off once the main computer recognizes the new module and the sensors sync up. If you believe the sensors need to be cleaned you may do so. Do as minimal as possible to make sure you are not damaging the sensor or disrupting the wiring inside. A bad connection would make the lights stay on. With so many lights that are effected by the module being illuminated, the module is likely bad or does not have a connection. Check the connection first and then resort to replacing the unit. For more help with these electrical tests, contact our service department.
I hit a curb pretty hard.. 5 to 10 minutes later my traction control light and my reduce engine power light came on.. Now ive cha
ANSWER : Any fault/error (or damage to the vehicle) that will affect drivability or vehicle performance "can" cause reduced power. Consequently, the codes that have caused the traction control warning light to illuminate should first be downloaded and if those codes implicate any of the possible causes of reduced power, those codes should be fully resolved first. Once that step is accomplished, that is once the traction system is EITHER ruled out, or once repairs are made if there was damage due to the collision, if the reduced power issue remains, such would be resolved in a Reduced Engine Power Warning Light Diagnostic. The bottom line is, you can just simply request a reduced power diagnostic but, as noted, the mechanic will first consider the possibility that the underlying cause is a traction system fault. If the cause of reduced power is not found "there", it then becomes a reduced power diagnostic. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
My check engine light and traction control lights are on and the cruise control light is flashing on and off.
ANSWER : Hi There,
What you are describing is common for a vehicle with traction control when it has been activated in a situation as you have described. The cruise control is also controlled in some cases by the traction control system and may be flashing as a need to have it reset due to the traction control being activated under those circumstances. The traction control system monitors the steering stability of the vehicle and engages when loss of traction has been detected. This is done by the use of electronic sensors at each of the four wheels that communicate with the Power Train Control Module (PCM) regarding steering performance and stability in adverse weather conditions. The traction control system works by reducing engine speed and determining which wheel to apply brake pressure to in order to prevent the vehicle from sliding. The anti-lock braking system and the traction control system work together to maintain the stability of the vehicle. The computer uses this information received from electronic sensors regarding the rotational speed of each wheel, the horizontal motion of the vehicle, and the vertical motion of the vehicle to determine how to direct the traction control system or the anti-lock braking system to best control the vehicle when needed. In some cases, the traction control system may simply need to be reprogrammed. I would recommend having a professional from YourMechanic come to your location to properly diagnose your traction control system.

Traction light/reduced engine power and check engine light coming on
ANSWER : Hello. From what you describe, it would appear that your vehicle may be experiencing some sort of intermittent wiring or sensor issue. If the problem occurred again after driving over a bump, then it may be possible that a damaged or loose wire is shorting or having contact issues. A common issue that can cause stalling is a faulty crank position sensor or wiring. I would carefully examine the engine for any loose or damaged wires. If the Check Engine Light comes back on, I would recommend having the trouble codes scanned before resetting the computer.
Traction control light light/reduced power message. Engine light stays on when car turned off/on, but traction control will clear
ANSWER : Hi there. The P2135 OBD-II error code indicates that the Power Control Module (PCM) has detected an erroneous reading regarding the voltages transmitted by throttle position sensor A or B, the accelerator pedal position sensor and or the actual throttle plate. If one throttle position sensor is reading at half throttle and the other is reading at full throttle, the PCM will set a code P2135 because the voltage readings will be so remote that it is impossible for the data to be accurate. Typically, once a professional mechanic downloads all stored error codes, they will test drive a vehicle to try and replicate any symptoms you’re experiencing to correctly diagnose this problem. Once they determine what damage has occurred to sensors, or electrical connectors, they’ll be able to recommend repairs that will fix your issue. You should start by having a professional mobile mechanic complete a check engine light inspection first.
