W/Harness Inspection

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found ?






Power Circuit Inspection

1. IG "OFF" and disconnect TPS connector.
2. IG "ON" and ENG "OFF"
3. Measure voltage between terminal 4 of TPS harness connector and chassis ground.

Specification : Approx. 5V





4. Is the measured voltage within specification ?






Signal Circuit Inspection

1. Check short to ground in harness
(1) IG "OFF" and disconnect TPS connector and PCM connector.
(2) Measure resistance between terminal 7 of TPS harness connector and chassis ground.
(3) Measure resistance between terminals 7 and 5 (8) of TPS harness connector.

Specification : Infinite





(4) Is the measured resistance within specification ?
