Esteem L4-1590cc 1.6L SOHC 0 MFI 16V (1995)
Throttle Position Sensor: Adjustments
1. Disconnect negative cable at battery and disconnect TP sensor coupler.
2. Insert 0.45 mm (0.018 in) thickness gauge between throttle stop screw and throttle lever.
3. Loosen TP sensor screws.
4. Connect ohmmeter between A and B terminals.
5. First, turn TP sensor counterclockwise fully and then clockwise gradually to find position where ohmmeter reading changes from continuity to
infinity (no continuity). Then fix TP sensor at that position by tightening screw to specified torque.
Tightening Torque: (a): 2.0 Nm (1.5 lb ft)
6. Check that there is no continuity between terminals A and B when 0.6 mm (0.024 in) thickness gauge is inserted.
7. Check that there is continuity between terminals A and B when 0.3 mm (0.012 in) thickness gauge is inserted. If check result is unsatisfactory in
steps 6) and 7), it means that installation angle of TP sensor is not adjusted properly. Therefore, start all over again from step 1).
8. Connect coupler to TP sensor securely, and connect battery negative cable.
