What is the P2314 fault code What is the description of Ignition Coil “E” Secondary Circuit Failure? How do I fix the P2314 fault code What are the symptoms and causes of the P2314 error code? …..
What is the P2314 fault code? What does it all mean?
The ignition coil, located above spark plugs, is an electronic actuated coil that is controlled electronically by the powertrain controller module (PCM). Its function is to transmit electric current to spark plugs, causing them to ignite. A voltage signal from the battery, as well as a ground signal, activate and control the ignition spark and timing.
The check engine light and a fault code P2314 on your vehicle indicate that the PCM detected abnormal voltage conditions in the secondary control circuit. This is indicated by the letter E. To determine the correct circuit for your vehicle, consult the manufacturer’s repair manual. This code can also be found on misfire codes and other ignition system codes.
The wires that supply the coil with battery voltage are the primary circuit of an ignition coil. the voltage that is supplied to the coil by fuses, relays and other means. The secondary circuit includes wires and sparkplugs responsible for the transfer of high voltage spark from the coil into the sparkplug. The ignition coil is usually supplied with ground and battery voltage. The ignition coil ignites the spark plug when the ground signal is temporarily interrupted.
The spark plug is an essential part of gasoline-powered engines. The engine will fail to ignite if the primary voltage to it is not sufficient. An illuminated check engine light is often used to indicate a P2314 fault code.
Note: Depending on the vehicle manufacturer, P2314 might have a different definition. Refer to the relevant repair manual or database for the vehicle to see a complete description of the code.
Some vehicles are susceptible to the P2314 fault code, including but not limited to Dodge, Ram and Chrysler models, as well as some models of Mercedes Benz, Jeep, Porsche, Mercedes Benz, Jeep and Chevrolet.
What is the P2314 Fault Code?
Below are some reasons to set fault code P2314:
- – Defective ignition coil “E”
- – Damaged wires or loose connectors, open, or short circuit issues
- – Worn or defective spark plug
- – Defective spark plug wire
- Faulty relay/blown fuse
- Faulty fuel injector
- – Defective camshaft or crankshaft sensor or cable
- – Defective PCM
What are the symptoms for P2314 Fault Code?
You may experience the following symptoms if your vehicle has the code P2314:
- – Illumination for the check engine light
- – Increased fuel use
- – Reduced engine performance
- – Engine misfires when idle
- – No acceleration
- – Setting other fault codes (misfires and crankshaft sensor codes).
- – The PCM can be set to failsafe mode and limit engine horsepower
How to Fix the P2314 Fault Code
In certain cases, you can replace the sparkplugs to correct the problem. However it’s possible to not test the sparkplugs and have the problem go away.
The following repairs can help resolve the P2314 fault code
- – Replacing defective spark plugs and wires
- – Replace the defective ignition coil
- Repair of damaged wires, connectors, or open or short circuit problems in the ignition coil “E”, circuit
- – Checking the wiring and testing the crankshaft or camshaft sensor
- Repairing a damaged fuel injector
- – Replacement of or reprogramming a defective PCM
How Serious Is the P2314 Fault Code
P2314 fault codes are considered to be serious because they can cause misfires or other issues. You may experience slow acceleration, intermittent engine problems, or engine stalling. The vehicle should not be driven if the symptoms are severe.
