DTC codes / Chrysler codes / P1492
P1492 on a Chrysler vehicle means the powertrain control module (PCM) has detected a battery temperature sensor signal voltage that is higher than the expected range for the current conditions. The PCM uses this sensor to protect the battery from overheating during charging, and a high voltage reading typically indicates an open circuit, a disconnected sensor, or a faulty sensor ground.
Guidance is general and written for Chrysler vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
