W/Harness Inspection

P0113 Intake Air Temperature Sensor 1 Circuit High Input

Inspection/Repair - W/Harness Inspection

Ground circuit inspection

1. Ignition "OFF".
2. Disconnect IATS connector.
3. Measure the resistance between ground terminal of IATS harness connector and chassis ground.

Specification :Approx. 0 Ohms




4. Is the measured resistance within specification?






Signal Circuit Inspection

1. Ignition "ON" & Engine "OFF".
2. Measure the voltage between signal terminal of IATS harness connector and chassis ground.

Specification :Approx. 5 V




3. Is voltage within the 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.
3. Has a problem been found?
