  2. Disconnect all electrical connectors and wires that are not necessary for the repair.
  3. Inspect the electrical connectors and wires for any signs of damage. If any connectors or wires appear to be in need of replacement, then proceed to step 4.
  4. Reconnect all electrical connectors and wires that were disconnected in step 2.
  5. Reinstall the electrical components in the order they were disconnected in step 2.
  6. Replace any damaged or missing electrical components.
  7. Close the hood and test the electrical system to ensure all connections are properly made.

2. Inspect the air filter and replace it if it is dirty

  1. Locate the air filter in the car. It is usually located on the passenger side near the engine.
  2. Remove the air filter if it is dirty.
  3. Inspect the air filter for damage. If it is damaged, replace the air filter.
  4. Reinstall the air filter in the car.
  5. Test the air filter to make sure it is working properly.

3. Clean or replace the Mass Air Flow (MAF) sensor

  1. Remove the front bumper.
  2. Remove the air intake box.
  3. Remove the air filter.
  4. Remove the MAF sensor.
  5. Clean the sensor.
  6. Replace the MAF sensor.

4. Clean the throttle body and idle control valve (ICV)

-Disconnect the negative battery cable -Remove the air cleaner assembly -Remove the throttle body cover -Remove the idle control valve (ICV) -Check the air flow and clean any debris from the air flow path -Clean the throttle body and idle control valve (ICV) using a clean cloth and a solvent such as acetone -Install the throttle body cover, air cleaner assembly, and idle control valve (ICV) -Connect the negative battery cable

5. Inspect the spark plugs and replace them if they are worn out

  1. Check the spark plugs for wear and replace any that are worn or fouled.
  2. Check the voltage at the spark plugs and replace any that show a voltage below the manufacturer's specification.
  3. Check the firing order and replace any that are out of order.
  4. Check the ground connection at the spark plugs and replace any that are faulty.

6. Check the engine oil level and top it off if it is low

  1. Park the car in a level area.
  2. Open the hood.
  3. Locate the oil dipstick.
  4. Place a finger over the end of the dipstick.
  5. Pull the dipstick out until it reaches the "3" or "3.5" line.
  6. Replace the dipstick and re-inject the oil into the engine.
  7. Close the hood.
  8. Drive the car to a level area and park it.
  9. Check the oil level again and top it off if it is low.

If the answers above didn't work then you should also try:

  1. Inspect the oxygen sensors and replace them if they are faulty.
  2. Check for any exhaust leaks and repair them if necessary.
  3. If the error code persists, it may be necessary to replace the engine control unit (ECU).
