Throttle Position Sensor: Adjustments

THROTTLE POSITION SENSOR

This procedure can be used to check and/or adjust level C sensors only:

1. Install an EEC-IV Breakout Box, Rotunda T83L-50 EEC-IV, or equivalent.
2. Attach a DVOM, on 20V scale. Connect (+) to Pin 47 and (-) to Pin 46.
3. Turn ignition key to Run position, (do not start engine).
4. Adjust TP Sensor (rotate) until the DVOM reads 1.0V (0.9-1.1).
5. Tighten TP Sensor screws to 1.2-1.8 N-m (11-16 lb-in).
6. While watching the DVOM, move the throttle to wide open and back to idle position. For proper operation, the DVOM should move from 1.0 at least 4.0 and back to 1.0V.
7. Perform EEC-IV Quick Test.
