Change Engine Oil
WARNING: This page is about a different car, the 2002 Oldsmobile Intrigue. However, it is still accessible from the selected car via links, so may be relevant.
The IPC illuminates the CHANGE OIL indicator when the powertrain control module (PCM) determines that the engine oil should be changed. The IPC receives a class 2 message indicating the engine oil life from the PCM.
After the oil is changed, reset the engine oil monitor. Refer to OIL CHANGE REMINDER .
