The Powertrain Control Module (PCM) monitors the fuel volume consumed by the engine when in CNG mode. If the PCM determines that 2.5 gallons of CNG fuel was consumed during this drive cycle or multiple drive cycles and the CNG High Pressure Sensor voltage does not change more than 0.059 volts, the sensor is determined to be stuck and a fault is set. Two trip fault.
