Tests DD: Fuel Rail Pressure (FRP), Fuel Rail Temperature (FRT) and Fuel Rail Pressure Temperature (FRPT) Sensors
PINPOINT TEST DD: FUEL RAIL PRESSURE (FRP), FUEL RAIL TEMPERATURE (FRT) AND FUEL RAIL PRESSURE TEMPERATURE (FRPT) SENSORS
WARNING: Vehicle fuel systems are pressurized even when the engine is not running. To avoid fire or personal injury, disable the fuel delivery system and relieve fuel system pressure before removing any fuel system component. Refer to the fuel system information at the beginning of pinpoint HC. Failure to follow these instructions may result in personal injury
Note: With the engine running the FRP PID value may be 48-70 kPa (7-10 psi) higher than a fuel pressure reading taken with a mechanical gauge.
This pinpoint test is intended to diagnose the following:
^ fuel rail pressure ( FRP) sensor (6B288)
^ fuel rail temperature ( FRT) sensor (4702)
^ fuel rail pressure temperature ( FRPT) sensor (9G756)
^ harness circuits: FRP FRT and FRPT
^ powertrain control module ( PCM) (12A650)
