Drivable short-term, but fix now to avoid damage.
This code indicates a fault in an ignition coil's primary or secondary circuit, which the computer detects as an electrical problem in how the coil fires the spark plug. A faulty coil circuit causes misfires, leading to rough running, lost power, and possible catalytic converter damage if left unrepaired. Fixes usually involve replacing the faulty ignition coil or repairing its wiring and connectors.
$100 – $400
Varies by vehicle and root cause.
Only briefly, and not if the check engine light is flashing. A flashing light means an active misfire that can damage the catalytic converter, so it's safest to stop and get it repaired.
Most repairs cost between $100 and $400. Replacing a single coil and spark plug is on the lower end, while wiring repairs or multiple coils can raise the price.
Yes, it can be. Misfires from a bad coil circuit can damage the catalytic converter and leave you with reduced power, so it should be addressed quickly.
It can contribute, since a worn or fouled plug stresses the coil. Technicians often inspect both the coil and plugs together when diagnosing this code.
