my Genesis G70's engine light is flashing what should I do

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, engine oil, spark plug socket.
• Park the vehicle on a flat surface, turn off the ignition, and disconnect the battery before performing any repairs.

2. Retrieve Diagnostic Codes

• Connect the OBD-II scanner to the vehicle’s diagnostic port.
• Turn on the ignition (do not start the engine) and follow the scanner instructions to read error codes.
• Document any codes and refer to service manuals for specific troubleshooting related to those codes.

3. Inspect and Replace Spark Plugs

• Remove the engine cover if necessary.
• Use a spark plug socket to remove the spark plugs.
• Inspect for excessive wear or carbon buildup; replace if necessary.
• Torque new spark plugs to the manufacturer-specified value (usually around 15-20 lb-ft).

4. Check and Replace Ignition Coils

• Remove the ignition coils using a socket set.
• Inspect for cracks or signs of wear.
• Replace faulty coils with new ones, ensuring they are seated properly and secured.

5. Examine Fuel System Components

• Inspect fuel injectors visually for leaks or clogs.
• If necessary, use a fuel injector cleaning kit to clean or replace injectors.
• Ensure the fuel filter is clean and replace if it hasn't been changed in accordance with the maintenance schedule.

6. Reassemble and Reconnect

• Reattach any components removed during the inspection (engine cover, air intake, etc.).
• Reconnect the battery and start the engine to check if the issue is resolved.
