why does my Honda CR-V turn off while driving

Solution

1. Preparation

• Gather necessary tools and parts. Ensure the vehicle is parked on a level surface with the engine off and cool.
• Disconnect the battery’s negative terminal for safety.

2. Fuel System Inspection

• Tools Required: Fuel pressure gauge
• Check fuel pump operation:
  1. Reconnect the battery.
  2. Locate the fuel pump relay and ensure it is functioning correctly.
  3. Connect the fuel pressure gauge to the fuel rail and turn the ignition to the "ON" position without starting the engine.
  4. Verify that the fuel pressure meets the manufacturer's specifications (usually around 30-50 psi for CR-V).
• If pressure is low, replace the fuel pump.

3. Ignition System Repair

• Tools Required: Spark plug socket, torque wrench
• Inspect and replace spark plugs:
  1. Remove the ignition coils using the appropriate socket.
  2. Extract the spark plugs and check for wear or damage.
  3. Replace with new spark plugs, tightening to the manufacturer’s torque specification (often around 13 lb-ft).
  4. Reinstall the ignition coils.

4. Throttle Body Cleaning

• Tools Required: Throttle body cleaner, clean rags
• Clean the throttle body:
  1. Remove the air intake duct to access the throttle body.
  2. Spray throttle body cleaner inside the throttle body and wipe clean with a rag.
  3. Ensure the throttle plate moves freely without obstruction.
  4. Reinstall the air intake duct.

5. Electrical System Check

• Tools Required: Multimeter
• Test battery and alternator:
  1. With the engine running, use a multimeter to measure voltage at the battery terminals.
  2. Confirm the voltage is between 13.5 to 14.5 volts, indicating the alternator is charging properly.
  3. If the voltage is low, inspect and possibly replace the alternator.
