3.
Measure resistance between terminals 1 of the sensor harness connector and 48 of the PCM harness connector.
Specification : Approx. 0Ω
Ignition "OFF".
Disconnect PCM connector.
Measure resistance between terminals 1 of the sensor harness connector and 48 of the PCM harness connector.
Specification : Approx. 0Ω
Is resistance within the specification?
YES
▶ Go to "Terminal and Connector Inspection" procedure.
NO
▶ Repair open circuit and go to "Verification of Vehicle Repair" procedure.
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.
Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
Has a problem been found?
YES
▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure.
NO
▶ Go to "Component Inspection" procedure.
Check for open in signal circuit.
Measure resistance between terminals 5 of the sensor harness connector and 56 of the PCM harness connector.
Specification : Approx. 0Ω
Is resistance within the specification?
YES
▶ Go to next step as below.
NO
▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure.
Check for short to battery in signal circuit.
Ignition "ON" & Engine "OFF".
With IATS and PCM connector still disconnected, measure voltage between terminals 5 of sensor harness connector and 56 of the PCM harness connector.
Specification : Approx. 0V
Is voltage within the specification?
YES
▶ Go to "Terminal and Connector Inspection" procedure.
NO
▶ Repair open circuit and go to "Verification of Vehicle Repair" procedure.
