* Low oil level: The most obvious reason for a low oil level reading is that the oil level in your engine is actually low. Check the oil level using the dipstick and add oil if necessary.
* Faulty oil level sensor: The oil level sensor itself may be faulty and giving an incorrect reading. You can test the oil level sensor by disconnecting it from the engine and checking the resistance between the terminals. If the resistance is not within the specified range, the sensor is faulty and needs to be replaced.
* Wiring problems: There may be a problem with the wiring between the oil level sensor and the engine control unit (ECU). Check the wiring for any damage or loose connections. If you find any damage, repair the wiring and retest the oil level sensor.
* ECU problem: The ECU may be faulty and interpreting the signal from the oil level sensor incorrectly. You can test the ECU by connecting a diagnostic scan tool to the vehicle and checking the live data for the oil level sensor. If the live data is not accurate, the ECU may need to be replaced.
If you are unable to identify and fix the problem yourself, you should take your vehicle to a qualified mechanic for diagnosis and repair.
