F 350 4WD Pickup V8-7.3L DSL Turbo VIN F (1994)
Throttle Position Sensor/Switch: Adjustments
Throttle Position (FIPL) Sensor.
NOTE: To check the FIPL sensor for proper operation and to make any adjustments the engine MUST be turned off.
1. Perform Key-On, Engine-Off On-Board Diagnostics and wait for all the DTCs to be issued.
NOTE: The throttle must be held to the floor, during Key-On, Engine-Off On-Board Diagnostics until the codes have begun to issue from the
STAR Tester Transmission Control.
2. After the last DTC has been issued, press the Transmission Control Switch (TCS), this will initiate the FIPL sensor adjustment mode and allow the
STAR Tester to be used as an audible guide in setting the FIPL sensor.
NOTE: The STAR Tester remains in the adjustment mode for only ten minutes. Steps 3-5 must be completed within this time period. If the ten
minute time limit is exceeded this procedure must be repeated from Step 1.
3. Remove the throttle cable from the throttle lever on the right side of the fuel injection pump.
Throttle Position (FIPL) Sensor.
4. Insert the VRV Gauge Block T92T-7B200-AH (0.515 inch) between the gauge boss and the maximum throttle travel screw. Hold the throttle lever
open against the gauge block. A steady tone indicates the FIPL sensor is properly adjusted. If the setting is too low the STAR Tester will issue a
slow beep (1 per second), if the setting is too high the STAR Tester will issue a fast beep (4 per second).
NOTE: The FIPL sensor bracket is permanently attached to the pump with tamper-proof screws. Movement of the bracket is not intended as a
means for adjustment. If required, adjustment of the FIPL sensor may be accomplished by utilizing the clearance between the sensor to bracket
screws and the sensor. If the FIPL sensor bracket is loose, remove the epoxy from the bracket to pump mounting screws, adjust the FIPL
sensor/bracket assembly to obtain a steady tone, retighten the screws, and reapply epoxy to the screw heads.
