- Use the J 35616 GM Approved Terminal Test Kit for any test that requires probing the ECM harness connector or a component harness connector. See Special Tools .
- Use the Temperature vs Resistance table in order to test the IAT sensor at various temperature levels in order to evaluate the possibility of a skewed sensor. A skewed sensor could result in a driveability condition. If the engine has sat overnight, the intake air temperature and the engine coolant temperature values should display within a few degrees. If the temperatures are not within 3°C (5°F), refer to Temperature Versus Resistance - Engine Coolant Temperature Sensor .
- For an intermittent condition, refer to Intermittent Conditions .
