TC, Traction control problems gmc
Haven't been on the water much, I blew my engine in my fishing truck and been have issues for 3yrs with t.c in my Yukon. I took the Yukon to the dealer several times to no avail, googled it tried YouTube, no help. Well I finally got it solved so if your having t.c problems and you check your ground, and wire connections try this. First clean out your throttle body and MAF sensir, the is necessary, First change your throttle actuator, if it continues change the throttle module, and if it continues change you accelerator pedal.
You may get away with just changing the sensors on the throttle body and foot pedal. However for my 03 Denali the sensors are not separate.
Just and FYI, total cost about $450, ac delco parts off Amazon. 1/4 the cost of the dealership
Truck runs like a champ.
