why does my Honda CR-V Sixth Generation (2023-present) check engine light flash when accelerating

Solution

1. Preparation

• Gather tools and parts needed for repair.
• Ensure the vehicle is parked on a level surface and the engine is cool.

2. Address Ignition System Issues

• Tools Required: Socket set, torque wrench, multimeter
• Remove the engine cover if applicable.
• Disconnect the battery's negative terminal.
• Remove and inspect spark plugs; replace if fouled or worn.
• Check ignition coils for proper resistance using a multimeter; replace faulty coils.
• Reinstall spark plugs and ignition coils, tightening to the manufacturer's torque specifications.

3. Check Fuel Delivery

• Tools Required: Fuel pressure gauge
• Locate the fuel rail and connect the fuel pressure gauge.
• Turn the ignition to the "On" position (without starting the engine) to check for pressure.
• If pressure is low, inspect the fuel pump and fuel filter for clogs or failures. Replace if necessary.

4. Inspect for Vacuum Leaks

• Perform a visual inspection of vacuum hoses and connections.
• Use a smoke machine or carburetor cleaner to detect leaks around the intake manifold and hoses.
• Replace any damaged or cracked hoses.

5. Examine Exhaust System

• Inspect the exhaust system for blockages or damage, especially around the catalytic converter.
• If issues are found, replace the affected components.
