Be careful cleaning your throttle body! - Check Engine Light
I cleaned the throttle body for my 2010 Chevy Equinox and caused more issues than I bargained for. After putting it back on, my check engine light turned on with code P0223, which is triggered when the voltage output from the Throttle/Pedal Position Sensor/Switch to the PCM is too high. I also got messages "Service Stabilitrak" and "Reduced Engine Power", and it wouldn't accelerate past 25mph, so it was practically undriveable. For the 2010 model year the TPS sensor isn't serviceable so I had to put on a whole new throttle body assembly. Personally, I recommend leaving the throttle body attached to the car when cleaning it. This won't give you a deep clean, but it might prevent the possibility of needing a new assembly. Apparently on newer models you CAN replace the TPS, but if you have a 2010/2011 GM you might not be able to.
GM Truck Electronic Throttle Body (ETB) Relearn Procedure
Poor idle after a GM Throttle Body replacement install? We show you how to perform the PCM relearn procedure so your vehicle runs normally. Instructions: 1) Start and idle the engine in park for 3 mins (0:54) 2) Turn ignition off for 60 sec (1:05) 3) Start and idle the engine in park for 3 mins again. At this point, the engine should be idling normally. (1:08) NOTE: Check engine light may illuminate indicating idle speed diagnostic trouble. If idle speed has not been relearned, it may be necessary to drive the vehicle at speeds above 44 MPH. After the drive cycle, engine should idle correctly; if not: 4) Turn the ignition off for 60 sec and repeat Step 3 (1:43) Was this video helpful.
