Guide To P2335 OBD Error Code Solutions

<<See All OBD Codes

The trouble code P2335 can be elucidated as Ignition Coil "L" Secondary Circuit. The P2335 code is a generic OBD-II trouble code which indicates that there is an issue with the secondary control circuit in ignition coil ‘L’, and potentially other ignition coils. The ignition coils are connected to the engine, and a small spark plug wire is used to ignite the engine. It is the powertrain control module which would control each coil electronically, which ensures that ignition occurs optimally. The battery voltage is sent to the ignition coil, which would trigger the ignition spark which leads to proper engine ignition timing.

This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another. The ignition coil ‘L’ is being monitored by the engine control module. This trouble code would be set by the ECM when the voltage of the ignition coil ‘L’ would not be as per the specifications set by the manufacturer.

What causes this problem with the Ignition Coil "L" Secondary Circuit?

• There can be inoperative camshaft or crankshaft sensor
• Malfunctioning wiring
• Ignition Coil 'L' harness might be unlocked
• Ignition Coil 'L' circuit might have bad electrical connection
• The relay or blown fuse might be flawed
• PCM might be damaged
• Malfunctioning Ignition Coil 'L'

1. Fuel Tank Pressure Sensor - The fuel tank pressure sensor is part of the fuel pump assembly and is mounted on top of the tank or inside the tank. It is part of the evaporative emissions system and reads pressure in the fuel system to detect evaporative leaks, such as a loose or faulty gas cap. Replace faulty pressure sensor now!
2. Engine Control Module - Dead cells in batteries can cause a failure in the engine control module. Many times, a battery is left in the rig long after a cell has died. This would affect the grounding in the car battery.
3. Powertrain Control Module - If there are some faults in the PCM, then it may throw off the timing and fuel settings of the engine, which can negatively affect the performance. A flawed PCM may cause the vehicle to experience a reduction in fuel efficiency, power as well as acceleration.
4. Electronic Control Unit - Do you know that the poor performance or unexplained drops in fuel economy or efficiency are often associated to onboard car computer problems, or defective ECU issues?
5. Ignition Coil - There would be some issues related to engine misfiring when there is a failure in the ignition coils. A vehicle with a faulty ignition coil will also result in vibration when it is idling at a stop sign or light. You can always rely on us as we have best auto parts for our customers.
6. Diagnostic Tools - Use factory grade diagnostic tools to resolve OBD code P2335 error. Buy new diagnostic tools and equipment for us.

Here are some steps which you should follow in order to diagnose this fault code:

After verifying the P2335 code with an OBD-II scanner, the mechanic should begin with a visual inspection of all electrical components. Use the vehicle information source to search for applicable technical service bulletins (TSB). If you locate a TSB that matches the vehicle make and model, symptoms exhibited, and the code stored, it will help you to arrive at a diagnosis.

You may also need to obtain diagnostic flow charts, wiring diagrams, connector face views, connector pinout charts, component locations, and component testing procedures/specifications from the vehicle information source. All this information will be needed to correctly diagnose the stored code P2335. After that test drive the vehicle to see if the code P2335 is reset. Drive until one of two things happens: Either the PCM enters readiness mode or the code is reset. If the code is reset, continue with the diagnosis. If it is not, you are dealing with an intermittent condition which may have to worsen before an accurate diagnosis may be achieved. Now if the code has been restored, then you must continue with the diagnosis.

One should obtain connector face views, connector pin out charts, component locator charts, wiring diagrams, and diagnostic flow charts by utilizing your source of vehicle information. A visual inspection of associated wiring and connectors should be performed. Make sure to repair or restore the wiring that has been cut, burned, or flawed. Wiring on top of the engine is often defective due to wildlife attempting to stay warm in cold climates. The DVOM should be used to inspect the voltage and ground circuits at the ignition coil. If no voltage has been detected, then you should check the system relay and associated fuses. Restore the faulty relays or blown fuses as per the requirement. If voltage and ground have been detected at the coil, examine the corresponding ground circuit at the PCM connector with the engine running. If ground pulse is detected there, then there is an open circuit between the coil as well as the PCM. If no ground pulse is discovered there, then there is some fault in the PCM or there might be PCM programming error.

Common Mistakes When Diagnosing The P2335 Code

• Many a times the mechanics think that there is some issue with the ignition coils and spark plugs due to which the P2335 fault code is appearing, but in reality, this issue is occurring because of defective wiring and connectors.
