- Warm engine to normal operating temperature. Turn A/C off (if equipped). Start and run engine at idle. Disconnect anti-dieseling solenoid valve connector. Engine should stall. If not, replace solenoid assembly.
- Reconnect solenoid connector and restart engine. Connect a voltmeter to test connector terminals. See Fig 1. Depress clutch pedal and shift transmission into 5th gear.
- With clutch pedal depressed, increase engine speed to 3000 RPM. Quickly close throttle valve and check voltage. Voltmeter should read zero (0) during acceleration, 12 volts during deceleration.
- Shift transmission into Neutral and repeat test. Voltmeter should read zero (0) during acceleration and deceleration. If not, check Neutral detecting switch, harness, and connections. Repair or replace as necessary.
- Turn ignition off and disconnect throttle valve switch. Connect voltmeter to throttle switch connector. Start engine and slowly increase speed while noting voltmeter reading.
- Throttle valve switch should turn on when engine speed reaches 950-1350 RPM. Slowly decrease engine speed and note RPM at which throttle turns off. Throttle switch should turn off at 800-1200 RPM. If not, adjust switch until it turns on/off at specified RPM. See Fig 2.
