why does my Honda CR-V Sixth Generation (2023-present) check engine light keep coming on

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent electrical shorts.

2. Address Error Codes

• Use the OBD-II scanner to read and document the error codes.
• Clear the codes and take the vehicle for a short drive to see if they return.

3. Inspect and Replace Components

A. Gas Cap

• Remove the gas cap and inspect for cracks or damage.
• Replace with a new gas cap if necessary.

B. Spark Plugs

• Remove ignition coil covers using a socket set.
• Take out spark plugs using a spark plug socket; inspect for wear.
• Replace any worn or damaged spark plugs with new ones, ensuring proper torque (typically 13-15 lb-ft).

C. Vacuum Leaks

• Inspect all vacuum hoses for cracks or disconnections.
• Replace any damaged hoses and ensure all connections are secure.

4. Fuel System Check

• Connect a fuel pressure gauge to the fuel rail.
• Check for proper fuel pressure (consult manufacturer specifications).
• Inspect for leaks in fuel lines; replace any damaged lines.

5. Final Assembly and Testing

• Reconnect the battery.
• Start the engine and observe for any irregularities or returning check engine light.
• Re-scan with the OBD-II scanner to ensure no new codes are present.
