Possible Cause
Oil pressure sensor wiring is defective
Oil pressure sensor power supply is not correct
Oil pressure sensor is defective
Control unit is defective
Diagnosis and Solution
Check the oil pressure sensor wiring, connectors and contact surfaces of the connector pins (possible oxidation).
Oil Pressure Sensor
Check the 5 V power supply to the sensor.
Oil Pressure Sensor
Check the oil pressure sensor operation.
Oil Pressure Sensor
Check the ECU operation with another EEM3 controller. If the system is functional and the fault is not active with the replacement ECU, then the original ECU is defective.
