Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, oil filter wrench, and a multimeter.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Retrieve Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Record any trouble codes displayed and refer to a repair manual for further analysis.

3. Inspect Oil Level and Quality

Open the hood and locate the dipstick.
Remove the dipstick, wipe it clean, reinsert it, and then remove it again to check the oil level.
Inspect the oil quality; if it appears dirty or has a burnt smell, consider changing it again.

4. Verify Oil Filter Installation

Use the oil filter wrench to ensure the oil filter is securely attached.
Check for oil leaks around the filter. If leaking, replace the filter and ensure it is properly tightened to manufacturer specifications (typically 3/4 turn after the gasket contacts the engine).

5. Confirm Oil Type and Viscosity

Refer to the owner's manual for the recommended oil type (e.g., SAE 5W-20).
If incorrect oil was used, drain the oil and replace it with the correct type.

6. Inspect Air Filter

Locate the air filter housing and remove the cover.
Take out the air filter and check for dirt or damage.
Replace with a new filter if necessary, ensuring a proper fit.

7. Check Electrical Connectors

Locate the oil pressure sensor and related connectors.
Ensure all connectors are secure and free from corrosion.
If any connectors are damaged, repair or replace them.
