how to diagnose my Honda CR-V Sixth Generation (2023-present) if it keeps stalling while driving

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to ensure safety while working on electrical systems.
• Gather personal protective equipment such as gloves and safety glasses.

2. Fuel System Inspection

• Check Fuel Pump Functionality:
  • Locate the fuel pump relay in the fuse box and test it with a multimeter for continuity.
  • If faulty, replace the fuel pump relay.
• Inspect Fuel Lines:
  • Check for kinks or leaks in the fuel lines. Replace any damaged sections.
• Replace Fuel Filter:
  • Disconnect fuel lines from the filter using a line removal tool.
  • Replace the old filter with a new one, ensuring the flow direction matches the fuel flow.

3. Ignition System Check

• Replace Spark Plugs:
  • Remove the spark plug wires and use a socket wrench to remove old spark plugs.
  • Install new spark plugs, ensuring they are gapped correctly as per manufacturer specifications.
• Test Ignition Coils:
  • Remove the ignition coils from the spark plugs.
  • Test each coil using a multimeter for resistance. Replace any coils that are out of specification.

4. Air Intake System Inspection

• Replace Air Filter:
  • Remove the air intake cover and take out the old air filter.
  • Install a new air filter, ensuring it seats properly in the housing.
• Inspect Throttle Body:
  • Remove the throttle body from the intake manifold.
  • Clean the throttle body with an appropriate cleaner and a soft cloth, removing any carbon buildup.
