Test DA: Fuel Rail Temperature: Testing

WARNING: This page is about a different car, the 2002 Ford Pickup and 2002 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
    NOTE: If DTCs P0182 and P0183 are set and Fuel Rail Temperature (FRT) sensor is continually shorted, scan tool will show a default value of 138°F (59°C). Turning ignition off for more than 5 seconds should reinstate FRT sensor if it is functioning correctly and will display a sensor reading of actual FRT.

  1. 1) DTC P0182 Or P0183 Monitor FRTMPAB PID
    Connect scan tool to Data Link Connector (DLC). Turn ignition on. Using scan tool, access AFCM and select FRTMPAB PID from PID/DATA MONITOR & RECORD menu. Record FRTMPAB PID temperature reading. If FRTMPAB PID is defaulted at 138°F (59°C), leave scan tool connected and go to next step. If FRTMPAB PID is not defaulted at 138°F (59°C), go to step  3).

  2. 2) Reset FRT Value

    Turn ignition off for 5 seconds, then turn ignition on. Access FRTMPAB PID from PID/DATA MONITOR & RECORD menu and record temperature reading. If FRTMPAB is not defaulted at 138°F (59°C), leave scan tool connected and go to next step. If FRTMPAB PID is still defaulted at 138°F (59°C), perform COMPUVALVE CHECK  under QUICK TEST. If fault still exists, replace compuvalve.

  3. 3) Monitor FRTMPAB PID

    Ensure ignition is on. Access FRTMPAB PID from PID/DATA MONITOR & RECORD menu and record temperature reading. If FRTMPAB PID is between -79 to 260°F (-62 to 127°C), leave scan tool connected, clear DTCs and go to next step. If FRTMPAB is not between -79 to 260°F (-62 to 127°C), check for abnormal heat sources around compuvalve. If no abnormal heat sources exist around compuvalve, perform COMPUVALVE CHECK  under QUICK TEST. If fault still exists, replace compuvalve.

  4. 4) Retrieve DTCs

    Start engine and warm to normal operating temperature. Turn ignition on. Perform AFCM CONTINUOUS MEMORY SELF-TEST . If DTC P0182 or P0183 is present, perform COMPUVALVE CHECK  under QUICK TEST. If fault still exists, replace compuvalve. If DTCs P0182 or P0183 are not present, system is operating normally at this time.
