What the P2311 code means. P2311 is an OBD-II generic code for the engine control module (ECM) detecting ignition that coil D or the cylinder 4 secondary circuit has low ionization. This means the coils spark is not lasting long enough.
What does insufficient ionization mean?
According to the diagnostics for those codes, it saying that the pcm detects that the secondary part of the ignition system (plugs, wires, coil) has an incorrect burn time or not firing at all. Possible causes: plugs, wires, coil, asd power circuit from relay to coil, coil control circuit from pcm, or pcm.
What does code 351 mean?
Code P0351 is defined as “Ignition Coil ‘A’ Primary/Secondary Circuit Malfunction.” It’s an OBD-II diagnostic trouble code (DTC) that indicates a fault with ignition coil ‘A’ (a problem with the coil on cylinder #1 or its circuit).
What is code P2317?
OBD-II Code P2317 is defined as a Ignition Coil “F” Secondary Circuit. The ignition coil or coils are responsible for igniting the air/fuel mixture inside the combustion chambers. Without reliable performance from the ignition coil(s) the vehicle will stumble and misfire.
What is code P0360?
When the P0360 code is stored, it means that the vehicle’s PCM (Powertrain Control Module) detected a problem with the primary or secondary circuit with at least one of the ignition coils. Almost all modern vehicles that have a PCM were manufactured with a COP (Coil on Plug) system.
What is ignition coil a secondary circuit?
The secondary circuit is made of the secondary ignition coil windings, distributor cap, distributor rotor, spark plug cable, and spark plug. Distributor-less systems have no distributor cap or distributor rotor. The Secondary circuit transfers the spark to the spark plugs.
Where is ignition coil a secondary circuit?
The high voltage side of the system is called the secondary circuit. On modern vehicles it includes the coil pack and spark plugs. Current technology has done away with many ignition components of the past. This includes items such as the distributor, cap, rotor – and now even the spark plug wires.
Where is ignition coil A located?
Where is the coil? The ignition coil sits between the battery and, if the car is an older model, the distributor that ‘distributes’ the HT voltage it produces to each spark plug, via thick rubbery HT leads (one per plug).
How do I know if my ignition coil is primary or secondary?
The higher energy the coil, the lower the primary resistance will be. Test the secondary circuit by attaching one lead to the negative terminal of the coil, and the other to the terminal where the spark-plug wire plugs in. The reading on the multimeter will be in the range of 10,000 ohms.
How do I fix code P2317?
What repairs can fix the P2317 code?
- Replacing the ignition coil.
- Repairing or replacing wiring or connectors that are associated with the ignition system.
- Replacing the powertrain control module.
What can cause a P0306 code?
Misfires can be caused by many reasons from a faulty ignition system, fuel system, or internal engine failure. The most common reason for this to happen is faulty or worn-out spark plug coil packs, especially if it’s been a while since you had a tune-up.
