What is P0314 fault code? What causes the Single Cylinder Misfire, Cylinder Unspecified (Cylinder Unspecified), error? How do I fix the P0314 fault code What are the causes and symptoms of the P0314 error code?
What is the P0314 Fault code? What does it signify?
If the powertrain control module (PCM), detects an engine misfire or ignition failure in one of the cylinders, a code P0314 will be set. This is when the catalytic converter is damaged. The misfire may be intermittently, sporadically or continuous. The engine fault light is activated when the fault code has been set. If the misfire does no damage to the catalytic convert, the engine fault light may flash briefly while you accelerate.
To manage misfires, PCM relies on the crankshaft position sensor CKP and camshaft positioning sensors CMP. The PCM monitors the relationship of these sensors and compares them with an ideal reference signal stored within the PCM. An error code is generated if the deviation exceeds a predetermined percentage. The cause of the misfire will depend on the vehicle manufacturer. It may be an electrical fault or mechanical problem. The steps to troubleshoot depend on the vehicle model, crankshaft position sensor(CKP), camshaft positioning sensor (CMP), wire colors and vehicle make.

What is the P0314 Fault Code?
Here are some reasons why P0314 should be set.
- – Low fuel pressure
- – Engine vacuum leaks cause compression loss
- – Problems involving pistons or valves
- – Defective EGR system
- – Clogged catalytic convertor
- – Spark plugs that are worn or dirty
- – A defective ignition coil or module
- – Distributor and distributor roller failure (for vehicles with)
- – Spark plugs or coil wires that are defective
- – Corroded, damaged, or broken cables and connectors
- – Problems with signal circuit to crankshaft position sensor
- – Problems with signal circuit to camshaft position sensor
What are the symptoms for P0314 Fault Code?
You may experience the following symptoms if your vehicle has the code P0314:
- – Flashing or continuous engine fault light
- Engine misfire
- – Lower engine power
- RPM fluctuations at inactivity
- – Engine hesitation and engine stumbling during acceleration
- – Increased fuel consumption
- – An increase in emissions values
How do I fix the P0314 fault code?
Repairmen who deal with P0314 fault codes often make the common mistake of replacing ignition system components without first inspecting the system.
There are several repairs that can resolve the P0314 fault code.
- Repair of damaged, corroded or corroded cables, connectors and components
- – Checking, cleaning and replacing dirty spark plugs
- – Indicator coil replacement and checking
- For vehicles equipped with a distributor roller and distributor roller, replacement is possible
- – Repairing damaged spark plugs and coil wires
- – Replace the fuel filter
- – Cleaning or replacing fuel injectors
- – Repair of engine vacuum leaks
- If the EGR valve is found to be defective, replace it
- – Cleaning out the catalytic converter.
- – Repair of engine mechanical failures (valves, pistons rings, rings and compression losses, among others.
How Serious Is the P0314 Fault Coding?
A code P0314 set on your vehicle can lead to engine misfires that could cause damage to the catalytic convertor. If the problem is not addressed, the catalyst can be damaged and result in increased vehicle emissions. Engine misfires can also result in poor engine performance, poor acceleration, idling fluctuation, and other engine problems. To avoid engine damage, fault code P0314 should be fixed as soon as possible.
