Car showing code p0122 p0222 p2176
The throttle position sensor is the throttle body. Since this is a drive by wire setup the throttle body uses two TPS sensors to determine the throttle plate position. It opens the throttle based on the two PPS sensor located on the gas pedal. This is a tricky system to diagnose on a GM. More often than not it is a wiring issue and not a failed component. I have spent many hours tearing apart and repairing wiring harness for these problems.

On the side of the throttle body
SOURCE: changed the TPS on my 05 sedona and it reads P0122
this code may cause by: TPS not mounted securely. TPS circuit short to ground or another wire. Faulty TPS. Damaged computer (PCM). to fix this code you can try this: Carefully check the throttle position sensor (TPS), wiring connector, and wiring for breaks, etc. Repair or replace as necessary
Check the voltage at the TPS (refer to a service manual for your vehicle for specific information). If the voltage is too low that is indicative of a problem. Replace if necessary.
If recently replaced the TPS may need to be adjusted. On some vehicles the installation instructions call for the TPS to be properly aligned or adjusted, consult a repair manual for specifics.
If there are no symptoms at all, the problem may be intermittent and clearing the code may resolve the issue temporarily. If this is the case then you should definitely check the wiring to be sure it's not rubbing on anything, grounding, etc. The code may come back.

The air filter change is a real pain.
Remove driver side tire.
Remove driver side wheel well.
You will see the filter canister in the front of the wheel well.
I had a mechanic do it for me and it took him 1.5 hours. If you plan to do it yourself, be sure you have plenty of time and alot of patience.

The TAC (throttle actuator control) is where both TPS sensors reside. On an older system this would be the throttle body. This system uses redundant TPS and APP (accelerator pedal position) sensors. If the problem were with the APP then you should have a code for a correlation problem between the TPS and APP or one APP sensor to the other. The most common issue by far that I have found is carbon build up in the throttle bore causing the plate to be stuck open. Remove the air intake tube from the TAC assembly and see if there is a ring of carbon around the area of the throttle plate. If so then using carb spray and an old toothbrush, clean the throttle body out. You can hold the plate open manually to do this but make certain the key is off or you will set several other codes and the throttle plate will fight against you. You can also remove the TAC assembly to clean if you like, though I do not recommend it. When you are done you will need to start the vehicle and run in drive for a minute or so, then to park or neutral. A couple of these cycles will usually relearn the position of the plate so that you can test drive. (Carb cleaner in the intake manifold will usually make the first start difficult.) Clear the codes, test drive the vehicle normally, but increase the take off and stop hard a few times after a few minutes of easy driving. Check and clear any codes that may have set on the test drive. You will want to drive again normally and check for codes again. If you do not have carbon the most likely culprit will be the TAC itself. The TPS sensors are intergral so you usually need to replace the whole TAC. Though I have seen only a handful of them that actually need replacement.
Good luck
SOURCE: how to change serpentine belt in cobalt ss
You just remove any obstruction, such as plastic covers. Locate the belt, and remove/loosen applicable bolts. Depress or loosen tensioner as required. Replace belt, tighten all bolts. (got any manual?)
SOURCE: I got code p2176 I changed out the tps still got
P2176=Throttle Actuator Control System - Idle Position Not Learned
Did you use all you old sensors,or is some of them from the new engine,I would swap out the IAC sensor or check for wires not hooked up.
If it can't relearn to idle the Idle air control might be different then your old one,but its not registering with the computer
