This summary uses the existing diagnostic information shown in full below.
Your car's engine has a part called an ignition coil that helps start the engine. This code means there's a problem with the ignition coil on cylinder L, which might make the car run poorly or not start at all.
The ignition coil transforms the battery's voltage to a higher voltage needed to ignite the fuel. A fault in the secondary circuit of coil L indicates a problem in delivering this voltage to the spark plug.
P2335 indicates an issue with the secondary circuit of the ignition coil for cylinder L. The secondary circuit is responsible for delivering the high voltage from the ignition coil to the spark plug. A malfunction can cause misfires or prevent the engine from starting.
• Engine misfire
• Poor fuel economy
• Check Engine Light on
• Faulty ignition coil
• Damaged ignition coil wiring
• Bad spark plug
Ignition Coil: A component that transforms the battery's voltage to a higher voltage needed to ignite the fuel.
Secondary Circuit: The part of the ignition system that delivers high voltage from the coil to the spark plug.
• Use an OBD-II scanner to confirm the code.
• Inspect the ignition coil and its wiring for damage.
• Test the ignition coil with a multimeter.
• Replace the faulty ignition coil.
• Repair or replace damaged wiring.
• Replace the spark plug if necessary.
• OBD-II scanner
• Multimeter
• Socket set

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect ignition components.
• Replace spark plugs as per maintenance schedule.
• Avoid driving through deep water that could damage electrical components.
Engine Performance
• Avoid driving the vehicle until the issue is fixed to prevent further damage.
• Consult a professional mechanic if unsure about the repair.
Check if the ignition system components are covered under the vehicle's powertrain warranty.
This code has been more common in vehicles with high mileage or those that have not had regular maintenance on ignition components.
Moderate – Addressing this issue promptly can prevent further engine damage.
Ignoring this code can lead to increased emissions and potential engine damage, which may not comply with local emissions laws.
• Engine at operating temperature
• Vehicle in park or neutral
The ignition coil is located on top of the engine, near the spark plugs.
Q: Can I drive with a P2335 code?
A: It's not recommended to drive with this code as it can cause engine damage or lead to a breakdown.
Q: How can I prevent ignition coil issues?
A: Regular maintenance, including timely replacement of spark plugs and inspection of ignition components, can help prevent issues.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
