Diagnostic Aids
- Use the J 35616 Connector Test Adapter Kit for any test that requires probing the ECM harness connector or a component harness connector.
- Test the IAT sensor at various temperature levels in order to evaluate the possibility of a skewed sensor. A skewed sensor can result in a driveability condition.
- If the vehicle has set overnight, the IAT sensor and the ECT sensor values should display within 3°C (5°F).
- For an intermittent condition, refer to Intermittent Conditions .
