- Low oil level: Ensure the oil level is correct as per the manufacturer's recommendation. If the oil level is low, add oil to the specified level.
- Oil viscosity: Make sure you used the correct oil viscosity recommended for your vehicle. Check your owner's manual for the correct oil type and viscosity. Using an oil with an incorrect viscosity can affect oil pressure and cause the light to stay on.
- Oil filter issue: Ensure that the new oil filter is properly installed. An improperly tightened or defective oil filter can cause the oil light to stay on. Check that the oil filter is seated correctly and the gasket is intact.
- Oil pressure sensor: A faulty oil pressure sensor can send a false signal to the instrument cluster, causing the oil light to stay on. Check the oil pressure using an oil pressure gauge to confirm if there's sufficient pressure. If the oil pressure is within the specified range and the sensor is faulty, replace the oil pressure sensor.
- Malfunctioning oil pump: If the oil pump is not functioning correctly, it can lead to low oil pressure and cause the oil light to stay on. Verify the functionality of the oil pump by inspecting it or checking the oil pressure. If the oil pump is faulty, replace it.
- Engine oil passages blockage: Blockages in the oil passages can restrict oil flow and cause low oil pressure. Check for any obstructions in the oil passages or restrictions in the oil filter housing that may hinder proper oil circulation.
If you have checked and addressed all these potential causes and the oil light still persists, seek assistance from a trusted mechanic or an authorized service center for further diagnostics and repairs.
