why does my Renault Clio V (2019-Present) check engine light keep coming on

Solution

1. Preparation

• Gather tools and necessary parts.
• Ensure the vehicle is parked on a flat surface and the engine is turned off.
• Disconnect the battery to avoid accidental electrical shorts.

2. Retrieve and Address Error Codes

• Use the OBD-II scanner to retrieve error codes.
• Identify the specific issues indicated by the codes (e.g., P0300 for random misfire).
• Research any necessary repairs based on the codes.

3. Inspect and Replace Ignition Components

• Remove the engine cover (if applicable) using a socket set.
• Disconnect the ignition coils one by one, inspecting them for cracks or damage.
• Replace any faulty ignition coils and spark plugs as per specifications (typically every 30,000 miles).
• Reattach the ignition coils and cover, ensuring all connections are secure.

4. Check and Clean the Fuel System

• Locate the fuel filter and inspect for clogs; replace if necessary.
• Remove fuel injectors, clean them using a specialized injector cleaner, or replace if they are faulty.
• Reattach all components securely and ensure there are no leaks.

5. Inspect the Air Intake System

• Examine the air filter and replace if it is dirty or clogged.
• Inspect air intake hoses for cracks or leaks; replace any damaged hoses.
• Ensure the Mass Air Flow (MAF) sensor is clean and functioning properly; clean if necessary.
