P2314 - IGNITION COIL "E" SECONDARY CIRCUIT

Table Of Contents

    Description of DTC code P2314 Generic

    The ignition coils put the spark into the air/fuel mixture so that it ignites inside the combustion chambers. The Powertrain Control Module (PCM) delivers a switched battery voltage and ground signal to the ignition coils, which are used to activate the spark and control ignition timing.

    Multiple diagnostic systems use letters instead of numbers to refer to the location of a fault. In this case, the diagnostic code P2314 OBDII indicates a problem in the ignition coil secondary circuit voltage “E”, specifically it shows that there is a difference of at least 10% of the reference voltage, established by the manufacturer. For this reason, the Check Engine light will illuminate.

    Symptoms of fault code P2314 Generic

    • Malfunction Indicator Lamp (MIL) illuminated.
    • Lower engine fulfillment.
    • Engine hesitation during idle.
    • Increased fuel consumption.
    • PCM may disable the fuel injector functioning for an affected cylinder.

    Causes of OBD2 P2314 Generic

    The reasons for the P2314 OBD2 fault code are stored are:

    • Maybe the ignition coil controller circuit "E" is disconnected.
    • Perhaps the ignition coil "E" control circuit wiring is shorted to the ground.
    • Possibly the ignition coil "E" is faulty.
    • Faulty relay or a blown fuse.
    • Open circuit or short-circuit in wiring or wire connectors.
    • Malfunctioning camshaft or crankshaft sensor.

    Possible solutions of the DTC code P2314 Generic

    To troubleshoot the P2314 OBDII error code you must do the following:

    • Inspect all the wiring that is related to the ignition coil "E". Check that there are no wires with wear or burn points. Also, check that the connectors are correctly tightened and are not corroded. Repair or supplant any of these as necessary. Use a multimeter to verify that the cables have the resistance recommended by the manufacturer. Any wire that does not meet specifications should be replaced.
    • Replace the ignition coil.
    • Broken, burned, or fluid-tainted spark plug caps are likely to be considered defective. Reach the connection between the ignition coil and the spark plug wire. Test for high-energy ignition (HEI) at the spark plug.
    • If none is present, unplug the spark plug wire from the coil and inspect for any HEI there. If there is an HEI on the spark plug, it's probably that the spark plug is no longer good or that there is a PCM error. So you should proceed to replace and repair it.
