Question about 2005 GMC Canyon
My 2005 GMC Canyon has been losing power,idles rough,and the reduced power and traction fault light comes on when it ,out of the blue starts acting up.You may be going down the road and all the sudden loses all power and idles really bad yet still runs til i can pull over and turn it on and off a few times til it smoothes back out and runs good.It does this often while driving so i took it and had it put on a machine and they diagnosed it as the throttle body so i had it replaced with a new one and it did not fix the problem.Is there anyone that can help me in finding out what is wrong with my truck?Any solutions or opinions would be greatly appreciated!Thank you.

could be the crankshaft sensor causing the timing to be off if it has a coilpack type distributor or if it has a gear driven distributor then it could be either the distributor itself or possibly just cap and rotor

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 !
