Check Engine Oil Level
The oil level sensing system consists of the following components:^ An oil level sensor
^ The powertrain control module (PCM)
The oil level is indicated in the following manner:
1. The oil level sensor provides the oil level signal to the PCM on CKT 1174 (BRN).
2. The PCM processes the signal.
3. If the PCM determines that a low oil level condition exists, the PCM grounds CKT 1173 (BRN/WHT).
4. The CHECK OIL LEVEL indicator illuminates.
