Tools Required: OBD-II scanner, basic hand tools (sockets, wrenches), torque wrench.

2. Retrieve and Analyze Codes

Connect the OBD-II scanner to the diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve error codes and document them for further analysis.
Clear the codes and check if the engine light returns after starting the engine.

3. Reset Oil Change Indicator

Turn the ignition to the "ON" position without starting the engine.
Press the gas pedal three times within 10 seconds to reset the oil change indicator light.
Verify if the check engine light remains off after resetting.

4. Inspect Oil Pressure Sensor

Locate the oil pressure sensor (usually near the oil filter).
Disconnect the wiring harness and remove the sensor using the appropriate socket.
Test the sensor with a multimeter to ensure it is functioning correctly.
Replace the sensor if it is faulty, then reassemble and reconnect.
