  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. Turn ignition off and disconnect throttle valve switch. Connect voltmeter to throttle switch connector. Start engine and slowly increase speed while noting voltmeter reading.
  6. 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.
