NOTE: TP sensor is not adjustable on any model. Following procedure is only for TP sensor functional check.
Turn ignition off. Disconnect TP sensor 3-pin harness connector. See Fig. 1 or Fig. 2. Measure resistance between TP sensor connector terminals No. 2 and 3 (component side). Standard resistance value should be 700-3000 ohms. If resistance is as specified, go to next step. If resistance is not as specified, replace TP sensor.
Measure resistance between TP sensor connector terminals No. 1 and 2 (component side). Open throttle valve slowly from idle position to wide-open throttle position. Resistance should changes smoothly in proportion to the throttle valve opening angle. If resistance change as specified, go to next step. If resistance does not change as specified, replace TP sensor.
Reconnect TP sensor harness connector. Connect Hi-Scan Pro tool or equivalent to OBD-II Data Link Connector (DLC). See Fig. 3. Turn ignition on and monitor for TP sensor PID value. Voltage should be 0.1-0.875 volts at idle position and 4.25-4.70 volts at wide open throttle. If voltage is not as specified, replace TP sensor
I tmay be another problem like a vacuum leak or maybe the egr is plugged or the valve is open partially.
