Terminal & Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness(es) 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

Check Open or Short in power circuit
1. IG "OFF" and disconnect ETC Motor & TPS connector.
2. IG "ON".
3. Measure voltage between TPS2 power terminal of ETC Motor & TPS harness connector and chassis ground.

Specification :Approx. 5V








4. Is the measured voltage within specification?






Signal Circuit Inspection

Check short to ground in harness
1. IG "OFF" and disconnect ETC Motor & TPS connector and ECM connector.
2. Measure resistance between TPS2 signal terminal of ETC Motor & TPS harness connector and chassis ground.(Measurement "A")
3. Measure resistance between TPS2 signal and ground terminals of ETC Motor & TPS harness connector.(Measurement "B")

Specification: Infinite
















4. Is the measured voltage within specification?
