2001 C5 Corvette Reduced Power Mode: P102, P1102, P1220, P1514, P1516 Fault Codes Explained

Model: c5 corvette Fault Code: P1102 Posted: 2019-07-17 13:56

My 2001 C5 Corvette suddenly entered reduced power mode and is displaying active handling trouble codes: P102, P1102, P1220, P1514, and P1516. This occurred overnight. I've previously experienced wiring damage from mice chewing on cables in other vehicles, so I'm concerned about potential electrical issues. Any insights into these specific fault codes or recommended diagnostic steps? The codes point to throttle body circuits and possibly sensor-related problems—especially the TPS (Throttle Position Sensor) and MAF (Mass Air Flow) sensors. A thorough inspection of wiring harnesses, particularly in the throttle body area, is advised.

Could P1102 be a typo for P1120? All these codes relate to throttle body circuits. It's worth checking the TPS (Throttle Position Sensor) and MAF sensor wiring for damage, especially given your history of rodent-related wire chewing.

P1102 is likely a misprint for P1120. I'd recommend cleaning the air flow sensor first—this often resolves related issues and may clear up the fault codes.
