What does code P1293 mean?

Q: What does code P1293 mean?

CNG Pressure Sensor Voltage Too Low. P1293 on Chrysler vehicles means the powertrain control module (PCM) has detected a voltage signal from the compressed natural gas (CNG) pressure sensor that is lower 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 low voltage typically indicates a short to ground, a faulty sensor, or a wiring issue.
