Check Engine Oil Level

The IPC illuminates the CHECK ENG OIL LEVEL indicator in the message center when the PCM detects a low engine oil level condition and the engine oil level switch signal circuit is high. An open engine oil level switch indicates a low engine oil level and a closed engine oil level switch indicates the engine oil level is in the normal range. The CHECK ENG OIL LEVEL indicator illuminates for 60 seconds at the start of each ignition cycle when a low engine oil level condition is present. The IPC receives a class 2 message from the PCM requesting illumination.
