What does code P1292 mean?

Q: What does code P1292 mean?

CNG Pressure Sensor Voltage Too High. P1292 on a Chrysler vehicle means the powertrain control module (PCM) has detected a voltage signal from the compressed natural gas (CNG) pressure sensor that is higher than the expected range for the current operating conditions. The PCM monitors this sensor to ensure the CNG fuel system is delivering the correct pressure, and a voltage above the calibrated threshold indicates a fault in the sensor circuit or the sensor itself.
