why does my Volvo XC60 Second Generation (2018-2024) engine light come on

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the negative battery terminal to ensure safety.

2. Addressing Error Codes

• Connect the OBD-II scanner and retrieve the error codes.
• Research the specific codes to determine the likely issue (e.g., P0171 for a lean condition).

3. Component Inspection and Replacement

• Gas Cap: If the error code indicates an issue with the evaporative emissions system, inspect and replace the gas cap if it’s faulty.
• Vacuum Hoses: Replace any cracked or disconnected vacuum hoses if identified during inspection.
• Spark Plugs and Ignition Coils: If misfiring codes are present, inspect and replace worn spark plugs and ignition coils.

4. Fluid Checks and Changes

• If low engine oil or coolant is found, top off or replace as necessary. Use manufacturer-recommended fluids.
• Change the engine oil and filter if they are due for service.

5. Reassemble and Reactivate

• Reconnect the negative battery terminal.
• Clear any error codes from the OBD-II scanner.
