What does the codes p0106 p0122 and p1122 mean? How can I fix them?

P0106 - MAP/Barometric Pressure Circuit Range/Performance Problem P0122 - Throttle/Pedal Position Sensor/Switch "A" Circuit Low P1122 - (varies with manufacturer but usually throttle position sensor) Sounds like you have a few issues here and it's best to go one thing at a time. The MAP code could be a faulty MAP sensor or something else, needs to be diagnosed. The other codes could be from a faulty throttle position sensor, which may need to be replaced. Best bet is to go to a shop where they have the scan tools necessary to read sensor values and diagnose it.

Check your throttle body housing seal where it meets the throttle body. If worn or damaged replace it. GM # 96455810 is a $5 part. This was the P0122 DTC issue on my 2005 Chev Optra (Canada) sister car made by Daewoo in South Korea.
