The PO302 error code indicates that cylinder number two is experiencing misfires. Here are two simple DIY solutions you can try to solve this problem:
Method A: The Spark Plug
The spark plugs are located at the engine end of the wires under the plug covers that attach them. Carefully remove the spark plug and use a spark plug gapper to check the spacing. The spacing should normally be between 0.024 to 0.071 inches. If the spacing is incorrect, use the spark plug gapper to adjust it. If the spark plug is damaged, replace it with a new one.
Method B: The Ignition Coil
Ignition coils are usually installed directly at the cylinder head above the spark plug. Carefully remove the ignition coil from the engine and check for stains or damage. If the ignition coil is covered with engine oil or stains, clean it with a WD-40 cleaner. Otherwise, replace the damaged ignition coil with a new one.
After the repair, you can use the Zeus app to clear the error code and then re-scan your vehicle to ensure everything is functioning properly.
