Code P0352 Dodge Description

The P0352 diagnostic trouble code (DTC) for Dodge vehicles indicates an issue with the Ignition Coil 2 Circuit. This code specifically points to a problem with the electrical circuit that controls the ignition coil for cylinder 2. The ignition coil is a crucial component of the ignition system, responsible for converting the low voltage from the battery into the high voltage needed to ignite the fuel-air mixture in the combustion chamber. When the ignition coil circuit malfunctions, it can lead to misfires, rough idling, decreased fuel efficiency, and even engine stalling.

Common Causes of P0352 Dodge

  1. Faulty ignition coil: The most common cause of the P0352 code is a defective ignition coil for cylinder 2.
  2. Wiring issues: Damage to the wiring harness or connectors associated with the ignition coil circuit can also trigger this code.
  3. Electrical faults: Issues with the power supply or ground connection to the ignition coil can lead to circuit malfunctions.
  4. PCM (Powertrain Control Module) failure: A malfunctioning PCM, which controls the ignition system, can also be a potential cause of this code.

Symptoms of P0352 Dodge

  1. Misfires: A common symptom of a faulty ignition coil circuit is engine misfires, which can manifest as rough idling, hesitation, or jerking while driving.
  2. Decreased fuel efficiency: A malfunctioning ignition coil can lead to incomplete combustion, resulting in decreased fuel efficiency and increased fuel consumption.
  3. Engine stalling: If the ignition coil circuit fails completely, the engine may stall or have difficulty starting.
  4. Illuminated check engine light: The P0352 DTC will trigger the check engine light to illuminate on the dashboard, indicating a problem with the ignition coil circuit.

How to Fix P0352 Dodge

  1. Diagnose the issue: Begin by using a scan tool to retrieve the DTC and perform a visual inspection of the ignition coil and its wiring for any visible damage.
  2. Test the ignition coil: Use a multimeter to check the resistance of the ignition coil and ensure it is within the manufacturer's specifications.
  3. Inspect wiring and connectors: Check the wiring harness and connectors for any signs of damage, corrosion, or loose connections.
  4. Replace the ignition coil: If the ignition coil is found to be faulty, replace it with a new one following the manufacturer's guidelines.
  5. Clear the DTC: After completing the repair, clear the DTC using a scan tool and test drive the vehicle to ensure the issue has been resolved.

Cost to Fix P0352 Dodge

The cost of repairing the Ignition Coil 2 Circuit issue can vary depending on the specific vehicle make and model, as well as the labor rates in your area. On average, the cost of replacing an ignition coil ranges from $100 to $250, including parts and labor. Additional costs may apply if wiring repairs or PCM replacement are necessary. It's recommended to consult with a qualified mechanic or auto repair shop for a more accurate cost estimate based on your vehicle's requirements. Keep in mind that diagnostic time and labor rates can impact the final repair cost.

When is the Code Detected?

Each ignition circuit is continuously monitored by the Engine Control Module (ECM). The test fails when the ECM does not receive a valid pulse signal from the ignition coil.
