Q: What does code P1523 mean?

Electronic Throttle Control Throttle Return. P1523 on Chrysler vehicles indicates that the Electronic Throttle Control (ETC) system has detected a fault in the throttle return path, meaning the throttle plate did not return to its expected resting position when commanded or during the self-test. The powertrain control module (PCM) monitors the throttle position sensors and the throttle actuator motor to verify that the blade moves freely and returns to the default limp-home position when power is removed.
