Throttle Position (TP) Sensor
- TP sensor circuit malfunction should set a related DTC. If so, see related TESTS W/CODES article. Also see TP SENSOR ADJUSTMENT in ADJUSTMENTS article.
- Install jumper wires to enable connection of a DVOM in parallel between TP sensor harness connectors. Connect DVOM positive lead to Dark Blue wire terminal. Connect negative lead to Black wire terminal.
- Turn ignition on, engine off. Slowly depress accelerator pedal. Signal voltage should gradually change from less than one volt at closed throttle to about 5.0 volts at wide open throttle position. If reading is not as specified, replace TP sensor.
