Important: The engine oil level (EOL) switch is a simple float switch that is grounded when the engine oil level is OK. When the ignition is first turned ON, the PCM commands the low oil level lamp ON for a brief period of time in order to test the bulb (approximately 3 seconds). The PCM also inspects the engine oil level switch circuit at startup. If the engine has been running, the PCM performs a test routine based on engine coolant temperature in order to ensure that the engine oil has drained back into the sump before checking the state of the engine oil level switch. If the engine coolant temperature is between 15°C (59°F) and 130°C (266°F), the PCM compares the engine coolant temperature at the last key OFF to the engine coolant temperature at the current key ON. If the difference between the recorded temperature values is at least 12°C (54°F), the PCM will test the engine oil level.
