Engine Oil Pressure Sensor The engine oil pressure sensor is an absolute pressure sensor used to measure the engine oil pressure in the main oil passage. The engine oil pressure sensor detects the engine oil pressure for diagnostic purposes and sends signals to the ECM.
Engine Oil Pressure Sensor
The engine oil pressure sensor is an absolute pressure sensor used to measure the engine oil pressure in the main oil passage. The engine oil pressure sensor detects engine oil pressure for diagnostic purposes and sends signals to the ECM.
Condition 1: Low Oil Pressure Warning
The low pressure warning setpoint depends on engine speed. Faults can only be detected and recorded after the engine has been running for 8 seconds.
Condition 2: Low Oil Pressure
The very low oil pressure setpoint depends on engine speed. If very low oil pressure is detected, the ECM will immediately shut down the engine unless a critical event override is activated.
Condition 3: Engine Oil Pressure Sensor Failure
The ECM will detect a failure of the engine oil pressure sensor. The diagnostic light warns the user of the engine oil pressure sensor status. When an engine oil pressure sensor failure occurs, strategies related to engine oil pressure will be disabled. A failure of the engine oil pressure sensor will cause the engine to shut down. The faulty sensor should be replaced.
