This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the electrical circuit that controls one of the ignition coils. It's like one of the spark plugs isn't getting the electricity it needs to make the engine run smoothly.
The Engine Control Module (ECM) monitors the ignition coil circuits. If it detects a problem with the primary control circuit for ignition coil 'C', it sets the P0353 code.
The P0353 code is triggered when the ECM detects an open or short in the ignition coil 'C' primary control circuit. This could be due to a faulty ignition coil, wiring issues, or a problem with the ECM itself.
• Check Engine Light is on
• Engine misfires or runs rough
• Poor fuel economy
• Faulty ignition coil
• Open or shorted wiring in the ignition coil circuit
• Faulty ECM

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect ignition components.
• Keep the engine bay clean to avoid corrosion.
• Use high-quality ignition parts.
Engine Performance
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Regular maintenance can prevent such issues.
Check with the vehicle manufacturer for warranty coverage on ignition components.
P0353 is a common code for ignition coil issues and has been consistently reported in various vehicle models over the years.
Moderate – The vehicle may still run, but ignoring this issue can lead to more severe engine problems.
Driving with a misfire can damage the catalytic converter and increase emissions.
• Engine running
• OBD-II scanner connected
The ignition coil is typically located on top of the engine, above the spark plugs.
Q: Can I drive with a P0353 code?
A: It's not recommended as it can cause further damage to the engine and catalytic converter.
Q: How do I know if my ignition coil is bad?
A: Symptoms include engine misfires, rough idling, and poor fuel economy.
