Q: What does code P1517 mean?

Throttle Actuator Control (TAC) Module Performance. P1517 on a Chrysler vehicle means the Throttle Actuator Control (TAC) module has detected a performance fault within the electronic throttle control system, typically a mismatch between the commanded throttle blade position and the actual position reported by the throttle position sensors. The Powertrain Control Module (PCM) sets this code when the TAC module's internal self-test or rationality check fails, indicating the throttle actuator is not responding as expected.
