Circuit/System Verification

WARNING: This page is about a different car, the 2006 Saturn Ion 3. However, it is still accessible from the selected car via links, so may be relevant.

If the ignition has been OFF for 8 hours or more, the IAT and the ECT, should be within 6°C (11°F) of each other and also the ambient temperature. Turn ON the ignition, with the engine OFF, and use a scan tool to observe the IAT and ECT parameters.
