Inspection After Removal

Inspect the engine harness connector and coolant temperature sensor for the following:

• Cracked or broken connector shell
• Missing or damaged connector seals
• Dirt, debris, or moisture in or on the connector pins
• Corroded, bent, broken, pushed back, or expanded pins
• Chipped, cracked, extruded, or damaged sensor.

Repair or replace parts as necessary.

Measure the resistance across the sensor signal and return terminals to be sure they agree with the table shown below. If the sensor ambient conditions change, the resistance values should be measured only after 2.5 minutes of the ambient change.
