ABS light on, ESP light on,Traction OFF light on, engine light on, rides perfectly OBDI reads only Front Right Wheel Speed Sensor
I've cleared these codes so the lights would not annoy me on my dash but still have ABS, ESP, Traction OFF lights on along with engine light and the only fault my OBDI continues to show is the 1 and only problem is "Front Right Wheel Speed Sensor." My only other thought is because my car is 1000 miles to next service may play part in the engine light but I need advice.
My car has 94000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
If a faulty component is still in place, the fault codes will return almost immediately after clearing them. ABS, ESP, and traction control systems all rely on input from wheel speed sensors to determine as the name implies, the speed of each wheel. When a wheel, or wheels are spinning faster than others due to wheel slip or the vehicle is sliding, the ABS and ESP systems can reduce throttle input as well as apply braking to an individual wheel or all of them if needed. With a wheel speed sensor fault code stored, these systems cannot determine the rate that all 4 wheels are spinning and sets a fault. That is why the abs/esp light is on. The system should be scanned by a certified technician and the wheel speed sensor replaced if found to be the cause. The warning lights will stay on and these systems will not function as designed until the fault is corrected. These lights do not come on to indicate a need for routine service. Rather they only come on when a component in the system is at fault.
How to Identify and Fix Common car Problems ?

If the brake system is malfunctioning, the traction control light might come on as a result. The light for your ABS might also come on if the brake fluid is low. Your car likely has sensors in those tanks in order to detect when fluids are low, which could be dangerous.
When the warning light is on, it could mean that a sensor has gone bad or needs cleaning. It could mean that the module has gone bad. A steady warning light indicates a problem that may affect your safety. A blinking light is a warning that your safety may be endangered if you drive.
The ABS light (usually yellow, amber or orange) should come on briefly every time you start your car as part of a system check. If the light stays on, that means something isn`t working and the system has been shut down. With ABS, sensors mounted at each wheel monitor the speed at which the wheels are turning.
If the TCS and the ABS warning lights both come on, along with the red main brake warning light, you should not drive the car until the problem has been fixed. Your entire braking system is affected, and may not be able to stop your vehicle when you need it to. Have your vehicle towed to a repair shop.
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 your TCS light is on and your Check Engine Light is flashing, it could indicate an engine misfire. This is one of the most damaging reasons for your engine light to flash and should be looked at as soon as possible.
Start your vehicle, and while parked, turn the steering wheel as far as it can go to the right, then do the same but to the left. Repeat this process a few times, then turn off the vehicle. When you restart your vehicle, the light should be reset.
On all car models, the ESP G419 sensor unit is installed under the left seat.
Resetting Your ABS Dashboard Warning Light
Step One: Disconnect the positive cable from your car battery. Then, hold down the brake pedal to drain the vehicle`s electrical system. This will result in a reset of the car`s central computer. Plug the cable back in to restore power.
Yes, in a somewhat indirect way. As we`ve mentioned, your car`s ABS light can be triggered by low brake fluid. Worn brake pads deplete your brake fluid. By doing this, they can trigger your car`s ABS light.
The four common reasons that typically cause this light to turn on include a malfunctioning ABS module, low levels in the fluid reservoir, broken wheel speed sensors, or the system is turned off. Your ABS actually shares some important components with another system in your vehicle: your traction control system.
While low tire pressure can cause a variety of problems, it generally will not cause the ABS light to come on. If you see the ABS light come on and your tire pressure seems normal, it`s a good idea to have the ABS system checked by a mechanic.
The primary input of the TCS is the wheel speed sensor. These sensors continuously monitor the speed of each driven wheel and send the data to the ABS and Traction Control System ECU. When a slip is detected between the tire and the road, the TCS regulates brake pressure on the slipping wheel.
It is not safe to drive with the ESP BAS light on, especially in slick conditions. This is because the ESP BAS light indicates that there`s an issue with the vehicle`s electronic stability program or brake assist system.
How do I fix my traction control light? Quickly depress the gas pedal three times. Next, fully engage your engine and let it run for a minute. If there is no underlying issue with your traction control system, the TCS and ABS lights should reset and disappear.
Failure in the TCS can hamper your wheels from properly spinning and cause you to lose control over the vehicle on slippery roads, which harms your tires` surface, engine performance and raises the risk of accidents.
Why is My ESP Warning Light On? If your Electronic Stability Programme (ESP) warning light is on, this will usually indicate that you are either driving on a slippery surface or that there is a problem with your electronic stability program system.
What Causes ESP to Malfunction? A common cause is a faulty wheel speed sensor, often described as an ABS sensor. Bolted to the suspension, down in the depths of the wheel, brake and hub assembly.
ABS and ASR prevent the wheels from locking and slipping. ESP stabilizes the vehicle in critical situations by applying braking forces to the appropriate wheels.
How does an ESP® work? The key components of an ESP® are the ESP® Hydraulic Unit, wheel speed sensors, the steering wheel angle sensor, yaw-rate and lateral acceleration sensors, and the Engine Control Unit (ECU).
When you steer erratically, the ESP also tells your engine to cut down on power, which has an impact on how much power is sent to each wheel. Unfortunately, when driving in bad weather, the failure of this system can be quite dangerous and result in serious accidents.
Removing a wheel speed sensor will disable ABS—and sometimes, stability control. If your car has a yaw sensor, you can unplug that for results. You can also try simply unplugging the ABS module, though that could adversely affect your car`s braking performance.
If the ABS light on the instrument panel illuminates, our technicians recommend checking the battery first. A weak battery can cause the ABS light to turn on. A brake light that is not working or has burned out can also cause the ABS light to illuminate.
4. Does A Faulty ABS Module Drain My Battery? An ABS module failure can cause the ABS pump to run continuously. This can eventually drain out your vehicle battery.

Can front wheel drive car engine power rear wheel drive
ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.

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.

Battery light goes on when I start car then turns off, if I rev engine light comes back until rpms go down. Abs goes comes on/off
ANSWER : Batteries can die due to faults in the charging system so ideally a suspected "faulty" battery should be load tested before a decision is made to condemn it. The only exception to this rule is if the battery is already clearly "old" (greater than 5 years) but even then once you put a new battery in, as a replacement for a "dead" battery, you have to comprehensively check out the charging system. Diagnostic Trouble Code P0460 will result in disruption of the dashboard fuel gauge’s ability to accurately report your tank’s fuel levels. The fuel gauge readings may be erratic, or read somewhere off scale. Vehicles equipped with a low fuel warning light feature may also suffer from erratic low fuel warnings in the event of a code P0460. Unless the P0460 code has been reported alongside other trouble code, all of the vehicle’s essential systems should otherwise function normally. I would recommend that you request a check engine light diagnostic to first resolve the fault causing the P0460 code to set. The check gas cap light warning light could be due a faulty gas cap and/or small leaks in the EVAP system.
Check engine light – O2 sensor circuit + speed sensor circuit…
ANSWER : Hi there. O2 sensor low voltage can be caused my a number of things. Mass air flow sensor was only one of them. It can be a bad O2 sensor, coolant temperature sensor, or wiring issue.
What should be done is a proper diagnosis for the Check Engine Light. Using a complete scanner rather than just a code reader gives a technician the opportunity to not only read trouble codes, but to read voltages for individual sensors. While a code reader tells you the relevant system that set the Check Engine Light on, but with a number of possible causes, the full scan tool allows checking of each individual cause. Having a proper diagnosis will help you have this repaired correctly without replacing parts that are not faulty.
Chrysler 300 2005 abs not working. Code c2116. Does this mean my abs pump is dead for sure? Or could it be abs sensors.
ANSWER : Hi there. Take a digital volt meter and check the voltage on the harness to the ABS control motor. There should be a battery voltage present. If the voltage is low, then there is a break in the wiring from the computer to the ABS control motor. If the voltage is normal, then the ABS control motor has a burned cell and the ABS controller assembly would need replaced. This will effect the ESP system as well and set off the lights. If you need further assistance with your ABS system not working, then seek out a professional, such as one from Your Mechanic, to help you.
While driving on freeway truck goes into a limp mode, and the check engine light, abs light, parking break light, service brake
ANSWER : It is possible that you could be having an issue with your powertrain control module. This is somewhat of a common problem on many GM vehicles. I would recommend having your vehicle inspected by the dealership to determine if the powertrain control module is functioning properly. If not, a reflash of the powertrain control module may resolve the issue but often times it must be replaced.
What caused my wheel speed sensor failure?
ANSWER : A wheel speed sensor is the most common failure in the ABS system. The reason your engine management and traction control light are also on is because those systems "borrow" wheel speed information from the ABS system. The reason the fail so often is because they live in a hostile environment. They hang out there inside the wheel well and have to make every movement that the wheel does, up and down and left and right. They get wet in the rain and frozen in the snow and they are exposed to all of the road dirt as well. So it’s easy to understand why the wheel speed sensor doesn’t last the lifetime of the car. If you need assistance, YourMechanic can send a technician to your home or office to replace your wheel speed sensor and get you back on the road with a minimum of trouble.
