Liftgate hydraulics stopped working 2003 GMC Envoy SLT
Service Engine Soon came on yesterday morning. Heard about gas cap issue and tightened cap. Stayed on. I had an appt this morning and opened my liftgate to get stuff out. Came out of my appt, started my Envoy, and the Service Engine Soon had turned off. Got to the grocery store and the liftgate hydraulics won't work. Is it all electrical?

I have a 2003 GMC Envoy and my issue is when I shut the blower off it still ... Can this issue also be remedied ...
Hello: Without being there when the smoke test was performed no one can say what the results of the smoke test were. I would go back to the dealer and speak to the service director/service manager and request a new gas cap.
If they forgot to tighten the hose clamps on the hose from the tank to the filler cap it could be setting it off. If they are all tight it was probably just the gas cap. The gas cap is usually ALWAYS the culprit. Let me know if this helps
Your going to have to get the Envoy PCM scanned for the DTC codes to address the issue. There are just to many things that can cause your Check engine light to come on. It can range from a faulty gas cap to a faulty O2 sensor.
Good luck and keep us posted, thank you for using fixya.
First thing to do is to clean the throttle body and throttle plate thoroughly. While performing the cleaning, disconnect the battery for about 30 minutes. This will force the PCM to relearn with a clean throttle body. See if this helps with running and the codes. Also make sure the gas cap is tightened properly.
NO , gas cap not the issue here . the P2176 refers to throttle actuator control system - idle position not learned .... the test for this is a mile long , i would try clearing the code , and see if it returns , or it will reset itself if it see's 3 drive cycles without a failure . cheers.
