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 all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.

3.

Has a problem been found?

▶ Repair as necessary and then go to "Verification of Vehicle Repair" procedure.

▶ Go to "Crankshaft Position Sensor Circuit Inspection" procedure.
