Equipment Hookup


Verify that minimum idle is at specified value.
Make all checks/adjustments with engine at operating temperature.


Fuel Injected Models: Disconnect harness connector from TPS. Using three six-inch jumper wires, reconnect harness to TPS. With ignition on and engine not running (as applies), connect a digital voltmeter to black wire (-) and either of the two other colored wires (+). If voltage is approximately 5 volts, this is the reference voltage lead. Connect DVOM to other wire in this case. Check reading against specified value. If TPS is adjustable, loosen the unit retaining screws and rotate the unit to reach specified value.
