Chrysler 300 2005 abs not working. Code c2116. Does this mean my abs pump is dead for sure? Or could it be abs sensors.

Chrysler 300 abs not working. Code c2116. Does this mean my abs pump is dead for sure? Or could it be abs sensors. There were stores codes for both front abs sensors and the rear right one. How would I go about diagnosing it after testing the fuse box and all the fuses were fine? From your expierence could code c2116 be caused by faulty abs sensors? Even though the scanner said it was low voltage to the pump? Just to clarify my abs and esp are not working and their lights are on.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
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.

Common Faults:

C2116 – ABS Pump Motor Supply Low Voltage is the most common fault code to be stored.

DTC C2116: Abnormality in pump motor power supply voltage. If there is any problem in the CAN bus lines, an incorrect DTC may be set. Prior to this diagnosis, diagnose the CAN bus lines (Refer to GROUP 54C, Trouble code diagnosis ). Whenever ECU is replaced, ensure that the CAN bus lines are normal.
Common reasons for this to happen: ABS is malfunctioning: Traction control and ABS (anti-lock braking system) often share the same control module and internal self-diagnostics system. As a result, sometimes an issue in the ABS can trigger the traction control light.
Common ABS pump and module failure for the Jeep Patriot will constantly illuminate the ABS warning light. Fault code C2116 – motor fault/supply voltage low is the most common code to be found.
What the P2173 code means. Code P2173 means that there is a vacuum leak somewhere in the intake system or one or more of the sensors that monitors intake pressures has malfunctioned.
The P2767 code is a generic powertrain code related to the transmission or gearbox. In particular, it states that the engine control module (ECM) is receiving incorrect information from the input/turbine speed sensor B.
Throttle position sensors are mounted to the side of the throttle plate and measure the position of the throttle — essentially, how far down the gas pedal is pressed.
P0340 Causes

A defective camshaft position sensor.

Dodge Caliber ABS pump and module failure will cause fault warning lights to remain illuminated and fault codes to be stored for C2116 – Pump Motor Fault / Pump Supply Low Voltage. This will prevent the ABS braking system from working correctly.
P0016 is the OBD-II generic code indicating that the camshaft position sensor for bank 1 does not correlate to the signal from the crankshaft position sensor.

Getting 2 then 4 abs codes, brake shutters, speedo dies and engine slowes when Brake and absolutely lights come on,
ANSWER : You definitely want to start by inspecting the front and rear wheel speed sensors; a failure in these circuits will result in several other problems. Begin by connecting a scanner to see if the Powertrain Control Module (PCM) is registering the sensors accurately. With the scanner, you should be able to monitor all the wheel speed sensors while driving. Keep in mind, the rear wheel speed sensor is mounted on the transmission and is the sensor that runs your speedometer.

Once you determine which sensor is not registering, visually inspect the wiring harnesses and, if everything looks good, replace the sensor. In most cases, the sensor is the problem. If you suspect a wiring problem that isn’t visually apparent, you will need to do a continuity test from the PCM to the sensor connector.

If you determine that all the speed sensors are good, you should suspect a problem with ABS pump. The C0267 trouble code indicates there is a wiring problem in the harness to the ABS pump. It is possible that this is the main problem. To test this, you should disconnect the connector from the ABS pump and visually inspect the pins on both ends. A continuity test should be performed in this harness as well.

There are more test procedures for this that are a bit involved. If you are interested in digging more into this, you should pick up a factory repair manual, not a Chilton. The factory repair manuals are superior and you definitely want good information to make a correct diagnosis of your car.

If you need help with this, I recommend an "ABS light is on" inspection.

Good luck!

Just replaced head gasket, changed crack sensor new plugs. The check engine light is on, but dim, the only other light that the dash is a normal battery indicator. The fuel pump is not running when switch is turned on, the power windows don’t work, it turns over but not firing. It’s like only one part of the system is working. Also the heater fans work even if the switch is off.
ANSWER : I would first look at the diagnostic trouble codes. Those codes are available because the check engine light is on. If the fuel pump is not running (momentarily) at key on, that fault alone will prevent the car from starting as there will be no fuel pressure. Pump output and pressure can be directly tested and you can also check for electrical power to the pump. To find out why the engine will not run, the recommended diagnostic is a no start diagnostic. If you request that service, the responding certified mechanic will get this taken care of for you.

It threw a code 21 , throttle position sensor bad code. i replaced it and the code went away but i still have no spark.
ANSWER : Hello and thank you for contacting YourMechanic. The problems that you are encountering with your vehicle, could be caused by the harness to the Throttle Position Sensor (TPS) or the computer itself.

Check the harness to the TPS for any debris or any corrosion. Hook up a paperclip to the harness and turn on the key. Use a multimeter and check for voltage at the pins of the harness. Make sure that the ground on the sensor is grounded and has no resistance. If you find that the harness is having too much resistance, then I recommend having the main engine harness replaced. If you have replaced the harness and still have the same problems, then the computer will need to be flashed or replaced.

I recommend having a professional, like one from YourMechanic, come to your home to diagnose your car’s no start condition before replacing any parts.

My code reader says I have a bad mass air flow sensor ans crank shat sensor test drive ran better shut off & engine Lt. Same code
ANSWER : Hi there. The problem you are describing, sounds like you may have a poor connection in the connector at the mass airflow sensor. Although, sometimes aftermarket parts do not perform as well as factory (OEM) parts. Check for corrosion and/or wide spacing in the terminal ends. Compare the terminal ends in the connector using a flashlight to see better. The terminals can be tightened. If you are not comfortable with doing that, a replacement pigtail (connector) is available. You vehicle may require further diagnosis performed with a scanner that provides parameters that can be viewed as the fault occurs. If that is the case, I recommend having your vehicle’s electrical circuits inspected in order to pinpoint the underlying fault.

check engine light O2 sensor already replaced same codes still popping up after replacing old O2 sensor
ANSWER : Hi there. What you received from the parts store was a code retrieval, not a diagnostic. The codes are set when a fault is detected against normal operating parameter. The computer does not know what caused the fault, only that the fault meets the criteria for this code to set. There could be a problem in the wire harness, converter, or the ECM. The code and data are needed to properly assess the direction that a diagnosis needs. I strongly suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a check engine light inspection.

I had a p0405 get code replaced egr valve, map sensor,mad sensor, and PCv valve just to be safe but still getting the code why?
ANSWER : The code P0405 and a rough idle is most likely due to carbon getting into the EGR pintle. This will hold the EGR open. When you are getting the rough idle you should shut off engine and remove EGR valve. Check to see if carbon is holding the pintle open. If it is then you will have to remove the carbon from the pintle. Then try and clean out the EGR passages by scrapping them using a round wire brush. Afterwards, start the engine for a few seconds with valve removed to blow out loose carbon. You should then spray a small amount of carbon cleaner into the passages to dissolve the carbon. Lastly, reinstall the EGR and reset the light and codes.

If you’d like assistance with this, consider YourMechanic, as a certified professional can come to the vehicles locations to perform these checks and properly diagnose your Check Engine Light.

I put a cold air intake on my car I have replace the O2 sensor that is failing area code p0151 I’m not sure what to do mass is new
ANSWER : Hello. If the P0151 code persists after replacing the oxygen sensor, then it may be possible that the issue is with the wiring. If there is any damage or wear to the oxygen sensor connector or wiring there may be a compromise in the voltage, which can set off the light. I would carefully examine the wiring and connector for any signs of damage or wear. If the issue began only after installing the cold air intake, it may also be possible that the issue is related to the cold air intake. If you think that may be a possibility, I would try reinstalling the stock cold air intake to see if that may solve the issue.
