W/Harness Inspection

Engine Control
P0076 Intake Valve Control Solenoid Circuit-Low (Bank 1) - Inspection/Repair:_:W/Harness Inspection

Terminal & 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

Check voltage
1. IG "OFF" & Disconnect HO2S(S2) connector.
2. IG "ON".
3. Measure voltage between power terminal of the OCV harness connector and chassis ground.

Specification :B+




4. Is the measured voltage within specification ?






Control Circuit Inspection

Check voltage
1. IG "OFF" & Disconnect HO2S(S2) connector.
2. IG "ON".
3. Measure voltage between control terminal of the OCV harness connector and chassis ground.

Specification :Approx. 3.5V




4. Is the measured voltage within specification ?
