Code P0352 2021 Honda CR-V Description
The P0352 diagnostic trouble code (DTC) for a 2021 Honda CR-V indicates a No. 2 Cylinder Ignition Coil Circuit Malfunction. This means that the powertrain control module (PCM) has detected an issue with the ignition coil for the second cylinder in the engine. The ignition coil is responsible for converting the low voltage from the battery into the high voltage needed to create a spark in the spark plugs, which ignites the air-fuel mixture in the combustion chamber. When the ignition coil circuit malfunctions, it can lead to misfires, rough idling, poor fuel economy, and even engine stalling.
Common Causes of P0352 2021 Honda CR-V
- Faulty ignition coil
- Damaged wiring or connectors in the ignition coil circuit
- Issues with the PCM
- Worn-out spark plugs
- Faulty spark plug wires
Symptoms of P0352 2021 Honda CR-V
- Engine misfires
- Rough idling or vibrations
- Decreased fuel efficiency
- Engine stalling
- Illuminated check engine light
How to Fix P0352 2021 Honda CR-V
- Begin by diagnosing the specific cause of the issue using a scan tool to pinpoint the exact problem.
- Inspect the ignition coil, wiring, and connectors for any signs of damage or wear.
- Replace the faulty ignition coil if necessary, ensuring it is compatible with the vehicle's make and model.
- Check and replace the spark plugs and spark plug wires if they are worn out or damaged.
- Clear the DTC and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0352 2021 Honda CR-V
