What does Error Code P0353 mean?

Moderate Issue
DTC Code P0353 indicates an issue with the Ignition Coil 3 Control Circuit in vehicles with generic ignition systems. This code is triggered when the Engine Control Module (ECM) detects a mismatch between the commanded and actual state of the ignition control circuit for coil 3, affecting the spark event.

What are the symptoms of Error Code P0353?

  • Engine Light ON: The check engine light or service engine soon warning light illuminates, indicating a potential issue with the ignition coil 3 control circuit.
  • Lack/Loss of Power: The vehicle may experience a noticeable reduction in power, which can be linked to the malfunctioning ignition coil affecting engine performance.
  • Engine Harder to Start: Starting the engine may become more difficult due to the compromised ignition coil, affecting the ignition process.
  • Engine Hesitation: The engine may hesitate during acceleration, which can be attributed to the faulty ignition coil disrupting the ignition timing.
  • Rough Engine Idle: The engine may idle roughly, indicating an issue with the ignition coil that affects the smooth operation of the engine.

What causes Error Code P0353?

  • The ignition coil may be defective, leading to improper spark generation and engine misfires.
  • There could be an open or short in the wiring harness connected to Ignition Coil 3, disrupting the electrical flow.
  • Poor electrical connections in the circuit can cause intermittent or weak signals to the ignition coil.
  • The Engine Control Module (ECM) might be malfunctioning, failing to send the correct signals to the ignition coil.

How to fix Error Code P0353?

  • Verify DTC Code: Confirm the presence of DTC P0353 using an OBD-II scanner. Check for any additional codes that may be related to the ignition system.
  • Inspect Ignition Coil 3: Visually inspect the ignition coil for cylinder 3 for any signs of damage, corrosion, or loose connections. Ensure the coil is properly seated.
  • Check Wiring and Connectors: Examine the wiring and connectors leading to ignition coil 3. Look for frayed wires, poor connections, or corrosion that could affect the circuit.
  • Test Ignition Coil: Use a multimeter to test the resistance of the ignition coil. Compare the readings with the manufacturer's specifications to determine if the coil is functioning correctly.
  • Inspect Power Supply: Verify that the ignition coil is receiving the correct voltage from the power supply. Check the battery and alternator for proper operation.
  • Check Engine Control Module (ECM): Ensure the ECM is sending the correct signals to the ignition coil. Use an oscilloscope to check the signal waveform if necessary.
  • Perform a Swap Test: Swap ignition coil 3 with another cylinder's coil to see if the problem follows the coil. This can help determine if the coil itself is faulty.
  • Clear DTC and Test Drive: After repairs, clear the DTC and perform a test drive to ensure the issue is resolved and the code does not return.
