On a 20O6 Chevrolet Impala What is the purpose of oil sensor?
On a 2006 Chevrolet Impala, the oil pressure sensor's purpose is to monitor the pressure of the engine oil. It sends a signal to the car's computer (PCM or ECM) indicating the oil pressure. If the pressure drops below a safe level, the sensor will trigger a warning light on the dashboard (typically an oil can symbol) alerting the driver to a potential serious engine problem. Low oil pressure can lead to engine damage or even failure.
