Throttle Position (TP) Sensor Inspection

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.
Switch the ignition to ON.
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 ).
