Solution

1. Reset Oil Light

Turn on the Ignition: Do not start the engine, just turn the key to the "ON" position.
Access the Oil Life Reset Menu: Press the "Home" button on the dashboard, then navigate to "Settings" > "Vehicle" > "Oil Life".
Reset Oil Life: Select "Reset" to reset the oil life indicator.

2. Replace Oil Pressure Sensor (if faulty)

Preparation:
- Gather tools: Socket set, wrench, oil catch pan.
- Ensure the engine is cool and disconnect the battery.
Remove Engine Cover:
- If applicable, remove any engine cover using the appropriate socket size.
Locate the Oil Pressure Sensor:
- Identify the oil pressure sensor, usually located near the oil filter or engine block.
Disconnect Electrical Connector:
- Carefully detach the electrical connector from the sensor.
Remove the Old Sensor:
- Use the socket or wrench to unscrew and remove the faulty oil pressure sensor.
Install New Sensor:
- Apply a small amount of engine oil to the threads of the new sensor.
- Screw in the new sensor and tighten it to the manufacturer's torque specifications (typically around 10-15 lb-ft).
Reconnect Electrical Connector:
- Firmly reattach the electrical connector to the new sensor.

3. Recheck Oil Level and Quality

Add Oil as Necessary: If the oil level was low, add the correct type and amount of oil.
Start Engine and Check for Leaks: Let the engine run for a few minutes and check for any leaks around the oil filter and oil pressure sensor.
