SOURCE: dtc C0035,C0040, P2227,P2228 ENGINE LIGHT

The C0035 and C0040 are speed sensors trouble codes. The P2227 and P2228 are baro sensor error codes. Causes for it to go out of range are broken wires, disconnected connector, or a bad sensor. Check the voltage to the white/black wire on the connector, It should show 5V

Abslight stays on. How to fix? This is a2007trailblazer?


First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0186
DTC C0196
DTC C0201
DTC C0240
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0245
DTC C0283
DTC C0287
DTC C0290 or C0292
DTC C0455
DTC C0550
DTC C0558

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit

On grand prix2006 code C0040 which weel is that my computer tell me rear but no side


It is the right front (RF) ABS sensor that this codes corresponds to nothing to do with the rear.. Are you using a GM TECH 2 scanner? If not that is the problem.

2005 truck. What are the probable causes of DTCs C0035,C0040,and C0201?


C0035 is ABS Sensor in left front wheel
C0040 is ABS Sensor in right front wheel
C0201 is ABS Enable Relay Contact Circuit
You most likely have a poor ground connection or a faulty EBCM (Electronic Brake Control Module) for these conditions. I recommend having someone run a diagnostic test at a shop. I doubt the ABS issue is stopping the truck from cranking.

What is the corrective action for code c0055?


Apparently it is a speed sensor that is bad. I can see how it is related, just why it throws an ABS code is why I hesitate to say replace the speed sensor. Whether you have 4 wheel drive or 2 wheel drive, the sensor is the closet to the rear drive shaft. If the check engine light is on also for the speed sensor, then I would accept this.

05 gmc canyon traction control power fault


First you'll need to take it to have DTC's - diagnostic trouble codes check to find out what part of the system is at fault ! Could have a sensor , control module ,or wiring problem !
Traction Off Indicator The traction off indicator, which is a LED located on the traction control switch, illuminates only when the traction control switch has been pressed and released, disabling traction control. It is important to note that a traction fault does not illuminate this indicator and that there is no relationship between this indicator and the traction fault message.
Traction Fault Message The IPC displays the traction fault message when either of the following instances occur.
?€¢
The EBCM detects a malfunction that requires traction control to be disabled. The EBCM sends a serial data message to the IPC requesting that the message be displayed.


?€¢
The IPC detects a loss of serial data communication with the EBCM


Traction Control System (TCS)
When drive wheel slip is noted while the brake is not applied, the EBCM will enter traction control mode.
The EBCM uses a 5-volt pulse-width modulated (PWM) signal to request the PCM to reduce the amount of torque to the drive wheels. The PCM reduces torque to the drive wheels by retarding spark timing and by commanding the throttle actuator control. The PCM uses a 5-volt PWM signal in order to report to the EBCM the amount of torque delivered to the drive wheels.
You would need a factory grade scan tool to check data PID's - parameter identification , all the sensors work within a specific voltage range 1- 5 volts an you can see this on a good scan tool !
The Traction control is part of the ABS system an there a several DTC possible
DTC B0827 DTC B0828 DTC B2745 DTC C0035 DTC C0035 or C0040 DTC C0040 DTC C0055 DTC C0110 DTC C0191 DTC C0201 DTC C0220-C0229 DTC C0240 or P0856 DTC C0244 or P1689 DTC C0245 DTC C0267 or C0268 and C067 or C068 DTC C0550 DTC C0899 DTC C0900
You best bet is to take it to a qualified repair shop !

You

What does the codes c0055 and c0201 means


C0055 is for rear speed sensor, mounted on top of rear end. Unplug and remove 10mm bolt, remove. It's a magnet, any metal shavings? Change sensor and fluid. C0201 is ABS module fault. Under. Truck under drivers seat is the pump and module. Unplug it and check for moisture and corrosion. Clean and add DIEELECTRIC gel. Clear codes and retest. Might need another module. You don't need to remove pump just unbolt module from pump. Module was not common on this vehicle

I pulled the codes and here they are : C0036, C0035, C0040


Sounds like you need front wheel speed sensors. Replace the wheel bearings and sensors. May have an ABS unit fault, but more likely is both wheel bearings/speed sensors.
