P0192

Advanced Diagnostics - DTC P0192: Fuel Rail Pressure Sensor Circuit Low Voltage











General Description
The fuel rail pressure sensor senses fuel rail absolute pressure and converts it into electrical signals. The fuel rail pressure sensor outputs low signal voltage at low fuel rail pressure and high signal voltage at high fuel rail pressure. If the fuel rail pressure sensor output voltage is a set value or less, the powertrain control module (PCM) detects a malfunction and stores a DTC.

Malfunction Threshold
The fuel rail pressure sensor output voltage is 0.23 V or less for at least 2.0 seconds.

Diagnosis Details

Conditions for setting the DTC
When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory.

Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the battery.
