I own a automatic 2008 chevy cobalt 2.2 ecotec with 90k. My check engine light comes on first followed by "engine reduce power light". I,m getting a generic code of P2135 "Throttle Position Sensor/Switch A/B Voltage Correlation". I have a brand new factory throttle body and tps sensor that was installed. The light still comes back. Any suggestions? Thank you

Check the connection and make sure there is no rust. This code can also be an indication of PCM issue.

the new parts need to be calibrated with a good scan tool
