Low Oil Level Indicator

The PCM controls the low oil level indicator. The PCM samples the oil level once per ignition cycle, at power up only, if the criteria are met, indicating that the oil has had sufficient time to drain into the oil pan from the last power down. If the engine coolant temperature is greater than 75°C (167°F) at power down, the PCM will sample the oil level after 3 minutes have elapsed. If the engine coolant temperature is less than 75°C (167°F) at power down, the PCM will look for at least an 11°C (20°F) drop in the engine coolant temperature, before sampling the oil level at power up.
