Sub-Throttle Position Sensor: Turbo
- Disconnect electrical connector from sub-throttle actuator and sub-throttle position sensor. See Figure.
- Remove screws and sub-throttle actuator. Ensure no clearance exists between throttle stop screw and throttle valve gear with sub-throttle valve fully closed. Perform STEP 1. See Fig 1.
- With sub-throttle valve fully closed, insert specified thickness feeler gauge between throttle stop screw and throttle valve gear and then use ohmmeter to check resistance between specified terminals. See SUB-THROTTLE POSITION SENSOR RESISTANCE SPECIFICATIONS table. Perform STEPS 2 and 3. See Fig 1.
- Replace or adjust sub-throttle position sensor if resistance is not within specification. For adjustment procedures, see appropriate ADJUSTMENTS article. Reinstall sub-throttle actuator and electrical connectors.
