Control circuit inspection

1. Measure voltage between control terminal of the oil control valve harness connector and chassis ground.

Specification :Approx. 3 - 4V





NOTE:
Signal waveform in control circuit with ignition ON & Engine OFF




2. Is voltage within specification?






Terminal and 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.
