Q: What does code P1511 mean?

Throttle Control System Backup System Performance. P1511 on Chrysler vehicles means the powertrain control module (PCM) has detected a performance fault in the backup safety system that monitors the electronic throttle control (ETC) motor and its wiring. The PCM runs a self-test on the backup circuit and finds that the expected electrical response is missing or out of range, so it sets this code and typically commands reduced engine power.
