Throttle Position (TP) Sensor Inspection

WARNING: This page is about a different variant/trim than selected.

CAUTION:

The inspection cannot be performed with this method correctly if there is a malfunction of the APP sensor or throttle valve actuator. Verify that no DTCs related to the APP sensor or throttle valve actuator are stored before the inspection.

Connect the M-MDS to the DLC-2.
Turn the ignition switch to the ON position.
Verify that the TP sensor output voltage (M-MDS PID: TP1, TP2) is within the specification. (See PCM INSPECTION .)
- If not as specified, replace the throttle body. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION .)
