P2335 code definition

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:

What the P2335 code means

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.

What causes the P2335 code?

Several problems may cause a P2335 code including:

  • Damaged or corroded electrical wiring in ignition coil driver circuit from the ECM
  • Damaged or corroded connector for ignition coil L
  • Damaged or defective ignition coil L
  • Damaged or defective ECM (rare)

What are the symptoms of the P2335 code?

Symptoms of a P2335 code may include:

How does a mechanic diagnose the P2335 code?

A mechanic may use several methods to diagnose a P2335 trouble code, including:

  • Utilize an OBD-II scanner to check for a stored P2335 trouble code
  • Visually inspect all electrical wiring and connectors related to ignition coil L for signs of damage
  • Test vehicle for regular engine misfires
  • Perform a “wiggle test” on ignition coil L to check for a loose connection
  • Check wiring harness for damage
  • Use a digital volt/ohmmeter to test ignition coil L for a signal, if between 5 and 20, coil is faulty
  • Test ignition coil circuit for continuity

Common mistakes when diagnosing the P2335 code

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.

How serious is the P2335 code?

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.

What repairs can fix the P2335 code?

Several repairs can fix a P2335 trouble code and include:

Additional information related to a P2335 code

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.

Isai was able to arrive a little earlier than scheduled which was great. My car is an older car and it uses a carburetor not fuel injection. Finding a mechanic that knows how to work on a car with a carburetor can be a real challenge. I found Isai to be very knowledgeable and through. He answered all my many questions. He is very friendly. I certainly would use him in the future.
