What is the P2305 fault code What is the description of the Ignition Coil “B” Secondary Circuit Failure? How do you fix the P2305 fault code What are the causes and symptoms for the P2305 fault code …..
What is the P2305 fault code? What does it signify?
The ignition coil is located above the sparkplugs and is electronically controlled by the powertrain control module. Its function is to transmit electric current to the sparkplugs and ignite them. The voltage signal from a battery and a ground signals activate the ignition spark, timing and control them.
A check engine light along with a fault code P2305 indicates that your vehicle’s PCM has detected an abnormal voltage condition within the secondary control section of the ignition coil. The letter “B” is the indication. For more information, refer to the specific manual of the manufacturer. 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. battery voltage is sent through relays, switches, and other sources. The secondary circuit contains wires and sparkplugs which transfer the high voltage spark from coil to sparkplug. The ignition coil receives ground and battery voltage. The ignition coil ignites the spark plug when the ground signal is temporarily interrupted.
In gasoline-powered engines, the spark plug is an essential component. The engine will stop firing if the primary voltage to its ignition coil is inadequate. An illuminated check-engine light will usually accompany a fault code P2305.
Note: Depending on which vehicle manufacturer you are using, the definition of P2305 fault code may vary. Refer to the relevant repair manual or database for the vehicle to see a complete description of the code.
Vehicles prone at fault code P2305 include certain models of Mercedes Benz and Ford, Porsche, Dodge, Jeep, Chrysler, and Ram.
What causes the P2305 Fault code?
Below are some reasons to set fault code P2305:
- – Defective ignition coil “B”
- – Broken wires, loose connectors and open or short circuit problems
- – 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 of the P2305 Fault code?
You may experience the following symptoms if your vehicle has the code P2305.
- – Illumination for the check engine light
- – Increased fuel use
- – Reduced engine performance
- – Engine misfires when idle
- – No acceleration
- – Setting other fault codes (misfire and camshaft sensor codes, crankshaft sensor codes, etc.)
- – The PCM can be set to failsafe mode and limit engine horsepower
How do I fix the P2305 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.
There are several repairs that can resolve the P2305 fault code.
- – Replacing defective spark plugs and wires
- – Replace the defective ignition coil
- – Repair damaged wires, connectors or open or short circuit problems to an ignition coil “B”.
- – Checking the wiring and testing the crankshaft sensor/camshaft sensor
- Repairing a damaged fuel injector
- – Reprogramming or replacement of a faulty PCM
How serious is the P2305 Fault code?
Fault code P2305 can cause misfires or other issues. There may be slow acceleration, intermittent engine failures, and other issues with the engine. If severe symptoms occur, the vehicle should be stopped from being driven.
