P0353 Fault Code

Ignition Coil C Primary/Secondary Circuit Malfunction

• What does that mean?
• Symptoms
• Causes
• Solutions

The P0353 fault code indicates a malfunction in the ignition coil C primary and secondary circuit. This issue can disrupt the engine's normal operation and lead to poor performance. The ignition coil is essential for converting the battery's voltage into a high voltage needed to create a spark in the engine's cylinders.

What are the symptoms of the P0353 code?

Symptoms that may accompany the P0353 code are:

• Engine misfires or rough idling
• Decreased engine performance or power
• Illuminated check engine light
• Increased fuel consumption
• Difficulty starting the engine.

What causes the P0353 code?

Common causes of the P0353 code include:

• Faulty ignition coil C
• Damaged wiring or connectors associated with coil C
• Short circuits in the ignition coil circuit
• Poor connections leading to signal loss
• Faulty Engine Control Module (ECM) that fails to send the correct signals to the ignition coil.

How to fix P0353?

To resolve the P0353 error code, consider the following steps:

• Inspect the ignition coil C for any visible damage or wear and replace if necessary.
• Check all wiring and connectors for signs of corrosion, shorts, or breaks, and repair any issues found.
• Test the ignition coil circuit using a multimeter to ensure it is receiving and sending the correct voltage.
• Clear the fault code and perform a test drive to see if the problem returns. If it does, further diagnosis may be needed on the ECM.
