Low Oil Level Indicator

Chart:

The "LOW OIL LEVEL" Indicator ground is controlled by the Powertrain Control Module (PCM) which also supplies B+ to the Engine Oil Level Sensor, mounted in the Engine oil pan. The PCM will not check for a low oil condition, unless the drop in Engine Coolant Temperature corresponds with the chart above since the last Ignition "OFF" cycle when compared to the coolant temperature at the start of the current Ignition "ON" cycle.

If the coolant temperature drop conditions are not met, the "LOW OIL LEVEL" Indicator will come on for a 2 second bulb test only. (The Ignition must be "OFF" for a minimum of 5 seconds before the "LOW OIL LEVEL" Indicator can come "ON" again.) If the indicator comes on because of a low oil condition, it will stay on (even if oil is added to the crank case) for the rest of the current Ignition Cycle. A low oil condition exists with 2 3/4 or less quarts of oil remaining in Engine oil pan.
