Throttle Position Switch: Adjustments
MANUAL TRANSMISSIONEnsure that throttle plate is properly adjusted as outlined in "THROTTLE PLATE ADJUST" before adjusting throttle switch.
Fig. 7 Throttle switch test connections:
1. Disconnect electrical connector from throttle switch and connect ohmmeter between terminals 3 and 18 on switch, Fig. 7.
2. Meter should indicate continuity at wide open throttle and no continuity with throttle in any other position.
3. Connect ohmmeter between terminals 2 and 18 on switch, Fig. 7.
4. Meter should indicate continuity with throttle closed and infinite resistance as soon as throttle is opened.
5. If readings are not as specified, loosen switch mounting screws, adjust switch position, tighten screws and check switch operation.
6. If switch cannot be adjusted to obtain proper operation, replace switch.
AUTOMATIC TRANSMISSION
Ensure that throttle plate is properly adjusted as outlined in "THROTTLE PLATE ADJUST" before adjusting throttle switch.
Pin Designations (Throttle Valve View):
1. With throttle valve closed, resistance between connections #4 and #6 should be approximately 0 ohms.
Throttle Valve:
2. Loosen screws (1) and turn switch to adjust.
3. When switch is properly adjusted, resistance between connections #4 and #6 will go to infinite ohms immediately as throttle valve is opened.
4. Close throttle valve and resistance should return to approximately 0 ohms.
