Fuel Pressure Sensor/Switch: Service and Repair

Fuel Rail Pressure (FRP) Sensor









Removal and Installation

1. WARNING: Contact with exposed fuel injector wiring, if energized, may result in electric shock. Use care when working on or around energized fuel injector wiring. Fuel injector wiring supplies high voltage to operate the fuel injectors. Failure to follow this instruction may result in serious personal injury.

NOTICE: Make sure the ignition switch is in the OFF position prior to working on the electronic engine controls or the vehicle may be damaged.

Turn the ignition switch to the OFF position.

2. Remove the RH valve cover. For additional information, refer to Engine.

3. Disconnect the Fuel Rail Pressure (FRP) sensor electrical connector.

4. NOTICE: Fuel injection equipment is manufactured to very precise tolerances and fine clearances. To prevent fuel system damage, it is essential that absolute cleanliness is observed when working with these components. Always install fuel system caps on any open orifices or tubes.

NOTE: Do not reinstall a used FRP sensor. The FRP sensor is a one-time-use sensor due to the crush washer at the bottom of the sensor.

Remove and discard the FRP sensor.
- To install, tighten the new FRP sensor in 2 stages.
- Stage 1: Tighten to 7 Nm (62 lb-in).

- Stage 2: Tighten an additional 40 degrees.

5. To install, reverse the removal procedure.
- Bleed the high-pressure fuel system. For additional information, refer to Fuel Delivery and Air Induction.
