why does my Genesis G70 check engine light blink when I drive

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, torque wrench, fuel pressure gauge, multimeter.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent electrical shorts during repairs.

2. Address Ignition System

• Inspect and Replace Spark Plugs:

  1. Remove the engine cover (if applicable) using a socket set.
  2. Disconnect the electrical connectors from the ignition coils.
  3. Remove the ignition coils using the socket set.
  4. Extract the spark plugs using a spark plug socket and wrench.
  5. Inspect the spark plugs for wear; replace if necessary with OEM specifications (check gap).

• Replace Ignition Coils (if necessary):

  1. Install new ignition coils by reversing the removal process.
  2. Torque the ignition coils to manufacturer specifications (typically around 8-10 Nm).

3. Inspect Fuel System

• Test Fuel Pressure:

  1. Connect the fuel pressure gauge to the fuel rail's test port.
  2. Turn the ignition to the ON position without starting the engine to check the pressure reading (should be within manufacturer specs).
  3. If pressure is low, check the fuel pump and filter for issues.

• Replace Fuel Filter (if necessary):

  1. Locate the fuel filter and relieve fuel pressure by removing the fuel pump fuse.
  2. Disconnect the fuel lines and remove the old filter.
  3. Install the new filter ensuring proper orientation and torque.

4. Check for Vacuum Leaks

• Inspect and Replace Vacuum Hoses:
  1. Visually inspect all vacuum hoses for cracks or disconnections.
  2. Use a smoke machine or carburetor cleaner to detect leaks.
  3. Replace any damaged hoses with OEM replacements.

5. Clear Codes and Test Drive

1. Use the OBD-II scanner to clear any trouble codes.
2. Reconnect the battery and start the engine.
3. Test drive the vehicle to monitor performance and check if the check engine light remains off.
