Code P0353 2014 GMC Sierra Description

The ignition system on this engine uses ignition coils with integrated power transistors. The Engine Control Module (ECM) controls the spark event for each cylinder through individual ignition coil control circuits. When the ECM commands the ignition control circuit On, electrical current flows through the primary winding of the ignition coil, creating a magnetic field. When a spark event is requested, the ECM commands the ignition control circuit Off, interrupting current flow through the primary winding. The collapsing magnetic field created by the primary winding induces a high voltage in the secondary winding, which is connected to the spark plugs. The Diagnostic Trouble Code (DTC) will be set when the control circuit commanded by the ECM state does not match the actual state.

Frequently Asked Questions about P0353 2014 GMC Sierra Code

Q: What does the OBDII code P0353 mean on a 2014 GMC Sierra?

A: Code P0353 indicates a problem with the control circuit for ignition coil 3, which is responsible for delivering spark to one of the engine cylinders.

Q: What are the symptoms of a P0353 code on a 2014 GMC Sierra?

A: Common symptoms include engine misfires, rough idle, reduced power, difficulty starting the engine, and the check engine light turning on.

Q: What causes the P0353 code on a 2014 GMC Sierra?

A: Causes may include a faulty ignition coil, damaged wiring or connectors in the coil circuit, a malfunctioning PCM, or issues with the coil driver circuit.

Q: Can a P0353 code cause damage if left unresolved?

A: Yes, prolonged driving with this code can lead to engine damage, reduced fuel efficiency, and increased emissions due to misfires.

Q: How do you diagnose the P0353 code on a 2014 GMC Sierra?

A: Diagnosis involves inspecting the ignition coil, checking the wiring and connectors for damage, testing the coil’s resistance, and using a scan tool to monitor PCM signals.

Q: How do you fix the P0353 code on a 2014 GMC Sierra?

A: Repairs may include replacing the ignition coil, repairing or replacing damaged wiring or connectors, and in rare cases, replacing the PCM.

Q: Can a bad spark plug cause the P0353 code?

A: While unlikely, a bad spark plug can contribute to ignition issues, but this code is specifically related to the ignition coil’s control circuit.

Q: How much does it cost to fix the P0353 code on a 2014 GMC Sierra?

A: Repair costs vary but typically range from $150 to $300 for parts and labor, depending on whether the ignition coil, wiring, or PCM needs replacement.

Q: Can I drive my 2014 GMC Sierra with a P0353 code?

A: It’s not recommended to drive with this code, as misfires can damage the engine and catalytic converter over time.

Q: Is the P0353 code specific to ignition coil 3?

A: Yes, the code specifically identifies a fault in the control circuit for ignition coil 3. Other ignition coils would trigger different codes (e.g., P0351 for coil 1).
