P2335 is a diagnostic trouble code (DTC) for "Ignition Coil L Secondary Circuit". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
The P2335 code is a generic powertrain code related to the ignition system or a misfire. In this case, it means that the engine control module (ECM) has found a malfunction or fault in the secondary circuit of ignition coil L.
Codes related to the P2335 include:
Each cylinder has an individual ignition coil. Most OBD-II-equipped vehicles have a coil-on-plug system, which provides an ignition spark. The ignition coil will be secured to the engine so that it can use a small spark plug wire or plug boot.
All ignition coils, including ignition coil L, is controlled electronically by the vehicle’s ECM. A high-voltage spark is created through a pulsed electrical circuit. The majority of coil-over-ignition systems utilize a two-wire electrical connector, one for switched battery voltage and the second wire for a pulsed ground signal from the ECM. The switched battery voltage will range from around 12.6 volts to 13.8 volts. If the pulsed ground signal abruptly interrupts the ground circuit, the magneto inside of the coil will emit a high-voltage spark, which is transferred to the spark plug wire and used to ignite the air/fuel mixture that is inside the combustion chamber in order to cause an explosion.
The primary circuit is the electrical wiring from the ECM to the ignition coil. The secondary circuit typically includes the spark plug wires. A code P2335 code is stored with the secondary circuit has malfunctioned.
Several problems may cause a P2335 code including:
Symptoms of a P2335 code may include:
A mechanic may use several methods to diagnose a P2335 trouble code, including:
At times, general maintenance and tune-ups are done to fix a P2335 code, but the most likely culprit will be damaged or defective wiring. Vehicle’s that may have been stored for a longer period of time may have animals or rodents damaging wires as well.
Because a vehicle’s safe driving operation most likely will be impacted due to faults that store a P2335 code, this code is considered a potentially serious code. When this code appears, it is recommended to immediately take your vehicle to your local service center or mechanic for repair and diagnosis.
Several repairs can fix a P2335 trouble code and include:
Some vehicle manufacturers may disable the fuel injector on the affected cylinder. It is recommended to consult your service manual to see if your vehicle make and model will do this as well.
In addition, as other engine misfire or injector circuit codes may be present, it is recommended to repair codes in the order in which they appear, as subsequent codes may be a symptom of a larger problem.
