DTC codes / Chrysler codes / P1192
P1192 on Chrysler vehicles means the powertrain control module (PCM) has detected a low voltage signal from the inlet air temperature (IAT) sensor circuit, indicating the sensor is reading a higher-than-expected temperature or the circuit is shorted to ground. The PCM expects the IAT signal voltage to fall within a calibrated range as intake air warms, and a sustained low voltage tells the computer the sensor or its wiring is faulty.
Guidance is general and written for Chrysler vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
