Inspection

  1. Turn ignition off. Ensure throttle valve is in closed position. Disconnect TP sensor connector. Check for continuity between terminals "C" and "D" of TP sensor connector. Continuity should exist. If continuity exists, go to next step. If continuity does not exist, adjust TP sensor.
  2. Insert a feeler gauge of specified thickness between throttle lever and throttle stop screw. See TP SENSOR CONTINUITY table. Connect ohmmeter between terminals "C" and "D" of TP sensor connector. If continuity is not as specified, adjust TP sensor.
  1. Turn ignition off. Ensure throttle valve is in closed position. Disconnect TP sensor connector. Connect ohmmeter between terminals "C" and "D" of TP sensor connector. (Scheme 8) Insert a feeler gauge of specified thickness between throttle lever and throttle stop screw. See TP SENSOR CONTINUITY table.
  2. Loosen TP sensor screws. Rotate TP sensor until ohmmeter indicates continuity as specified. See «TP SENSOR CONTINUITY»(ref-18652-S32210402322000123000000) table. Tighten TP sensor screws. Open throttle valve fully a few times. Recheck TP sensor adjustment. If TP sensor is not adjusted as specified, replace TP sensor.

TP SENSOR CONTINUITY

Inspection Using DVOM

Ensure TP sensor is adjusted properly. See ADJUSTMENT under THROTTLE POSITION (TP) SENSOR CONTINUITY. On all models, turn ignition on. Using DVOM, measure voltage between ground and specified terminal at ECM/PCM. See TP SENSOR VOLTAGE table. See ECM/PCM LOCATIONS table. If voltage is not as specified, replace TP sensor
