Pinpoint Test Dd: Fuel Rail Pressure (FRP), Fuel Rail Temperature (Frt) And Fuel Rail Pressure Temperature (FRPT) Sensors: Introduction: Notes
WARNING: This page does not describe the selected car, but rather 30 other vehicles, including the 2006 Mercury Mountaineer, 2006 Mercury Monterey, 2006 Mercury Montego, 2006 Mercury Milan, and 2006 Mercury Mariner. However, it is still accessible from the selected car via links, so may be relevant.
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 TEST 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)
