What is the P2308 fault code? What does it signify?
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.
A check engine light and a fault code P2308 are indicators that your vehicle’s PCM has detected abnormal voltage conditions in the secondary control circuit. This is indicated by the letter C. For more information, refer to the specific manual of the manufacturer. This code could appear on misfire codes or other ignition system codes.
The wires that provide battery voltage to the coil are the primary circuits of the ignition coil. battery voltage is sent through relays, switches, and other sources. The secondary circuit includes the wires and sparkplugs that transfer high-voltage spark from the coil to spark plug. 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 essential for gasoline engines. Insufficient primary voltage to the ignition coil will cause a low-energy spark and an engine that is not running will fail. An illuminated check-engine light will usually accompany a fault code P2308.
Note: Depending on which vehicle manufacturer you are using, the definition of P2308 fault code may vary. Refer to the relevant repair manual or database for the vehicle to see a complete description of the code.
The P2308 fault code can affect certain vehicles, including but not limited to: Mercedes Benz, Porsche and Ram models, Dodge, Jeep, Chrysler, and Dodge.
What is the P2308 Fault Code and Why Does It Happen?
Here are some reasons why P2308 should be set.
- – Defective ignition coil “C”
- – Broken wires, loose connectors and open or short circuit problems
- – Worn or defective spark plug
- – Defective spark plug wire
- Faulty relay, or a blown fuse
- – A defective fuel injector
- – Defective camshaft or crankshaft sensor or cable
- – Defective PCM
What are the symptoms for P2308 Fault Codes?
You may experience the following symptoms if your vehicle has the code P2308:
- – Illumination at the check engine lights
- – An increase in fuel consumption
- – Lower engine performance
- – Engine misfires when idle
- – Inadequate acceleration
- – Other related fault codes (misfires, crankshaft and camshaft sensor codes).
- – The PCM can be set to failsafe mode to limit engine power
How do I fix the P2308 fault code?
Sometimes replacing the spark plugs can fix the problem. However, replacing spark plugs without testing might not be the best option.
Some repairs that could resolve the P2308 fault code are:
- – Replacing defective spark plugs and wires
- – Replacing the faulty ignition coil
- Repair of damaged wires and connectors.
- – Test the crankshaft sensor or camshaft sensor, and inspect its wiring
- Repairing a damaged fuel injector
- – Replacement of or reprogramming faulty PCM
How serious is the P2308 Code of Fault?
A P2308 fault code, which can lead to misfires and other problems with driveability, is considered serious. There may be slow acceleration, intermittent engine failures, and other issues with the engine. The vehicle should be stopped if the symptoms become severe and should be fixed as soon as possible.
