Throttle Position (TP) Sensor
Connect scan tool. Turn ignition on. With throttle fully closed, observe TP sensor voltage and throttle opening angle. TP sensor voltage should be 0.45-0.55 volt at 0.0 percent throttle angle. If necessary, loosen retaining screws and rotate TP sensor until correct voltages are obtained. Replace TP sensor if voltage cannot be adjusted to specification.
