I have a code of po122.tps i change the sensor .the check engine light still comes on it has 5 volts coming from plug please help

other sensor could be at fault, you will have to test all that are relater to the engine to determine the ones at fault. it can also be your computer malfunctioning. by resetting it, either the code will go away or you will get another code, maybe the same

Chungs at idle and emission code is given. O2

At this juncture you need to interface vehicle with appropriate scanner such as GM TECH 1 or equvalent and retreive codes to begin diagnostic.You have numerous outboard sensor parameters that could cause your driveability problem and anything prior to this is speculation.

Fault codes, p0102,p0122,po507

po102--maf sensor, could be a bad air cleaner and not letting air into engine, po122--tps pedal position sensor low, replace or adjust tps sensor,or wiring,po507--idle control system high input. for this you can take off idle air control, and clean out carbon from were it mounts on engine. it is just before throttle body at end of air intake hose, it is black. do not push on pintle on end of valve when cleaning, use a old toothbrush to clean carbon off of valve, use carb cleaner but do not soak valve in liquid of any kind. good luck!!
