Ignition Coil B Circuit Malfunction
The engine computer detected a problem with the ignition coil circuit for coil B. This can cause misfires, rough running, poor fuel economy, and hard starting.
You may be able to drive short distances, but the engine can run rough and may lose power. Continued driving can damage the catalytic converter and worsen the misfire.
P0352 means the powertrain control module detected an electrical fault in the ignition coil B primary or secondary circuit. This can be caused by a failed coil, wiring problem, connector issue, or a driver fault inside the engine control system. The code is often set when the PCM sees an open circuit, short circuit, or abnormal coil control signal.
It usually refers to one specific ignition coil identified by the engine manufacturer. The exact cylinder depends on the vehicle's coil numbering system.
Yes. A worn or damaged spark plug can overload the coil or contribute to misfire, which may help trigger this code.
Sometimes, but not always. Wiring, connector problems, and PCM driver faults can also cause the code.
No. P0352 is an ignition coil circuit fault code, but it can cause a misfire and often appears with misfire codes.
