What coil is coil D?
The powertrain control system (PCM) manages the ignition coils that ignite the spark plugs at precisely the right time. If the PCM detects a potential problem with the ignition coil “D” (which is the cylinder #4 ignition coil) or its circuit, code P0354 may be set.
What is the ignition coil D primary secondary circuit?
The P0354 fault code can be defined as Ignition Coil “D” Primary/Secondary Circuit Malfunction. It is the ignition system which would convert the battery voltage into the high voltage which is used to ignite the cylinder air/fuel mixture. The coil pack is generally a transformer which contains coils of wire inside it.
What is the OBD code for ignition coil D?
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.
What to do if your ignition coil is not working?
If you don’t detect any frequency signal from the PCM on the ignition coil driver circuit indicating the PCM is grounding/ungrounding the circuit (or there is no visible pattern on the scope if you have one) then leave the coil disconnected and check for DC voltage on the driver circuit at the ignition coil connector.
What is the DTC for ignition coil D?
P2311 is a diagnostic trouble code (DTC) for “Ignition Coil D Secondary Circuit”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.
How does the ignition coil work on a Ford?
The Engine Control Module ( ECM) controls each ignition coil operation. The ECM sends a ON/OFF signal to energize the ignition coil to create a spark at the spark plug when a spark is required at the cylinder. Need more information on how to fix the P0354 FORD code?
