Throttle Position (TP) Sensor

NOTE: All testing procedures are performed with engine at normal operating temperature. For further TP sensor diagnosis, see the TESTS W/CODES article.

Turn ignition on. With throttle fully closed, check and record voltage to ground at the specified ECM terminals. Refer to the TP SENSOR SPECIFICATIONS table.
If necessary, loosen retaining screws and rotate TP sensor until correct voltages are obtained. Replace TP sensor if voltage cannot be adjusted to specification.
