What does the engine code P2302 mean?
Definition: Ignition coil “A” secondary circuit
The P2302 engine code signals a faulty ignition coil or ignition coil electrical connection.

The price for an ignition coil is approximately $150 to $225. If you need to replace your ignition coil, expect to pay at least this much. If you aren’t doing the labor yourself, you will need to pay more for a mechanic’s labor—which will run you an additional $50 to $100.
Remember, these costs are estimates, and the cost will ultimately depend on the cost of parts and your mechanic’s costs for labor.
