Code P0352 2015 Chevrolet Silverado 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 P0352 2015 Chevrolet Silverado Code

What does the OBDII code P0352 mean on a 2015 Chevrolet Silverado?

P0352 indicates an issue with the ignition coil 2 control circuit, which could prevent the second cylinder from firing properly.

What are the common symptoms of the P0352 code?

Symptoms may include a misfiring engine, rough idling, reduced fuel efficiency, loss of power, and an illuminated check engine light.

What causes the P0352 code on a 2015 Chevrolet Silverado?

Common causes include a faulty ignition coil, damaged wiring or connectors in the coil 2 circuit, a malfunctioning PCM, or corroded electrical connections.

Can I drive my Silverado with the P0352 code?

Driving with a P0352 code is not recommended, as it can lead to poor engine performance, increased emissions, and potential damage to other engine components.

How do I diagnose the P0352 code?

Start by inspecting the ignition coil 2, its wiring, and connectors for damage or corrosion. Use a multimeter to check for proper voltage and continuity in the circuit. If no issues are found, test the PCM.

How do I fix the P0352 code?

Repairs may include replacing the faulty ignition coil, repairing or replacing damaged wiring, cleaning corroded connectors, or reprogramming or replacing the PCM if necessary.

How much does it cost to repair the P0352 code?

Repair costs depend on the exact issue but typically range from $50 to $300 for parts like an ignition coil and up to $1,000 if a PCM replacement is required.

Can a bad spark plug cause the P0352 code?

A bad spark plug typically wonâ€™t directly cause this code but may contribute to misfiring symptoms. The primary issue is with the ignition coil 2 control circuit.

Will clearing the P0352 code fix the problem?

Clearing the code will turn off the check engine light temporarily, but the underlying issue must be addressed to prevent the code from returning.

How can I prevent the P0352 code from occurring?

Regular maintenance, including inspecting ignition components, replacing spark plugs as recommended, and keeping electrical connections clean, can help prevent this issue.
