Throttle Position Sensor: Adjustments
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 other two colored wires (+). If voltage is approximately 5
volts, this is the reference voltage lead. Connect DVOM to the 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.
