P2314 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P2314 can be described as Ignition Coil "E" Secondary Circuit. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. This would also give rise to the illumination of the check engine light.

1. Electronic Control Unit – ECU monitors the temperature differences in the boost converter with the help of the temperature sensors to prevent the converter from overheating and malfunctioning. Thus, replace faulty ECU immediately.
2. Ignition Coil - Is your check engine light appearing on your dash? It is an indication that there are some defaults in your ignition coil. Don’t waste time and get them replaced or else this error code can turn up.
3. Fuel Tank Pressure Sensor – The fuel tank pressure sensor helps in many ways, most importantly by saving fuel, minimizing environmental pollution, and preventing damage to the engine. The pressure sensor, which is normally positioned inside or on top of the tank, works to detect the pressure in the fuel system, with the end goal of identifying leaks and defective gas caps. Thus, replace faulty sensor now!
4. Engine Control Module - ECM failures and faults can be very difficult to find and resolve as these are very rare and might require a complete reprogramming of the system to avoid wrong codes from getting stored in the system, leading to misdiagnosis. Replace it now!
5. Powertrain Control Module - Faulty PCM can disrupt the normal functioning of the vehicle by affecting the transmission system and the fuel delivery system. This will cause the system to store wrong OBD error and thus can lead to misdiagnosis.
6. Diagnostic Tool - In order to be that DIY guy, you need few diagnostic tools to get your car problems pointed out easily. Our diagnostic tools collection will come handy to do so, so why not have a look?

Do you wish to diagnose P2314 error code easily? Here are some steps which you should follow in order to diagnose this fault code:

The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle. 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 pin out 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 P2314. After that test drive the vehicle to see if the code P2314 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 P2314 Code

• Common mistakes while diagnosing this trouble code are unnecessary and expensive replacements which usually happen when one don’t follow all the steps carefully.
• The most common mistake while diagnosing this code is missing out on diagnosing steps which further leads to the expensive and unnecessary replacements. It is always recommended to seek help of experienced diagnostician to avoid any mistakes.
• A big mistake which is made by a lot of technicians is that they assume that this fault code is appearing because of faulty ignition coils and spark plugs, when in reality the actual reason is defective wiring and connectors.
