Throttle Switch

To test throttle switch circuitry, connect voltmeter across terminals "1" and "2" (both terminals on V6 engine). With ignition on and engine stopped, voltmeter reading at idle should be 2-8 volts (0 volts on V6 engine).
Above idle position, voltmeter reading should be 0 volts (2-8 volts on V6 engine). If throttle switch does not respond as outlined, test switch operation as follows:
With voltmeter still connected, ignition on and engine stopped, insert feeler gauge as shown in Figure.
Using feeler gauge listed in Throttle Switch Voltage Reading chart should produce voltages indicated in chart. If not, replace throttle switch and adjust as follows:
After replacing throttle switch, connect voltmeter and turn ignition on with engine stopped. On V6 engine, insert 0.012" (0.3 mm) feeler gauge as shown in Figure. Loosen lock nut and turn adjusting screw on throttle lever until meter reading drops to 0 volts. Tighten lock nut.

On all other models, insert 0.016" (0.4 mm) feeler gauge. Loosen throttle switch retaining screws until reading is indicated on voltmeter. Tighten retaining screws.
