P2016 Intake Manifold Runner Position Sensor/Switch Circuit Low (Bank 1) - 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?






Signal Circuit Inspection

Check short to ground in harness
1. IG "OFF".
2. Disconnect VCMA connector and ECM connector.
3. Measure resistance between VCMA feedback signal terminal of VCMA harness connector and chassis ground. (Measurement "A")
4. Measure resistance between VCMA feedback signal and VCMA ground terminals of VCMA harness connector. (Measurement "B")

Specification : Infinite
















5. Is the measured resistance within specification?
