Diagnostic Aids

WARNING: This page is about a different car, the 2002 Oldsmobile Intrigue and 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.

DTC P0125 is designed to detect a skewed ECT sensor or a faulty thermostat. A skewed IAT sensor may also cause this DTC to set. IAT sensor should read near ambient temperature while driving. See INTAKE AIR TEMPERATURE SENSOR RESISTANCE  table.
