What does D mean on Ford F250 ignition coil?
Which means that plugs, plug wires (if so equipped) or the spark plug itself is causing your F250 to throw P0354. Ignition Coil “D” indicates the problem is in the fourth cylinder. You’ll need to look up which cylinder is number four on your engine.
How to test Ford 4.6L coil on plug ignition?
If you’ve been wondering how to test the Coil-On-Plug ignition coils on your Ford car or truck (with a 4.6L or 5.4L V8) to see if one or several are bad and are causing a misfire, this is the article for you.
Where is the ignition coil located on a car?
The COP (coil on plug) ignition system is what is used on most modern engines. There is an individual coil for each cylinder that is controlled by the PCM (powertrain control module) It eliminates the need for spark plug wires by putting the coil right above the sparkplug.
What causes a DTC p0354 ignition coil D?
If an open or a short is detected in the driver circuit for coil #4, a P0354 may set. Also, depending on the vehicle, the PCM may also shut down the fuel injector to the cylinder also. Symptoms of a P0354 DTC may include: Potential causes of a P0354 code include: Short to voltage or ground on COP driver circuit
How to test Ford coil on plug ignition?
OK, to test the Coil-On-Plug ignition coils on your Ford car or truck, you need to know what each wire (circuit) does in the connector. Here are the circuit descriptions: Power (12 V) Circuit.

Where are the spark plugs on a DTC ignition coil?
There is an individual coil for each cylinder that is controlled by the PCM (powertrain control module) It eliminates the need for spark plug wires by putting the coil right above the sparkplug. Two wires are dedicated to each coil. One is a battery feed usually from the power distribution center.
Which means that plugs, plug wires (if so equipped) or the spark plug itself is causing your F250 to throw P0354. Ignition Coil “D” indicates the problem is in the fourth cylinder. You’ll need to look up which cylinder is number four on your engine.
What is the OBD2 code for Ford F250?
P0354 is a generic OBD2 code that indicates that ignition coil “D” has an issue with the primary or secondary wiring circuits. If your Ford F250 has thrown this code, it may be accompanied by P0304 .
How do you remove ignition coil from Ford truck?
Remove the fuel rails by simply unbolting the two bolts on the top, then gently pulling it up. Once you have located the ignition coil packs, proceed to step 2. Figure 1. Ignition coil packs. Figure 2. Fuel rails. Remove the bolts/connectors from the ignition coil in a numerical order. Figure 3. Remove in this numerical order.
What causes a p0354 on a Ford F250?
If your Ford F250 has thrown this code, it may be accompanied by P0304 . P0354 is a relatively straightforward diagnosis and is typically caused by a bad coil pack or wiring harness issue, although there can be caused by other factors. Primary or Secondary Wiring?
Where to find coil pack on Ford 2.3L?
If you have a 2.3L, 2.5L or 5.0L engine model, you may find two separate coil packs installed. Look at the front, upper and left hand side (driver’s side) of the engine. Alternatively, just follow the spark plug wires from the spark plugs to the other end of the wires. Unplug the coil pack assembly electrical connector (s).
How do you replace a coil pack on a Ford ignition?
Plug the spark plug wires into their corresponding terminal towers on the coil pack assembly. Attach the EGR vacuum regulator solenoid to the coil pack mounting bracket, if necessary, using the ratchet, ratchet extension and socket. Plug in the coil pack assembly electrical connector (s). Connect the negative battery cable using a wrench.
Do you need to know the color of ignition coils?
You don’t need to know the color of the wires for this test since the circuit descriptions (above) are shared by all of the eight Coil-On-Plug ignition coils on your Ford car or truck. So, whether you’re testing the number 1 cylinder ignition coil or the number 4 cylinder ignition coil (or whichever ignition coil), the above info applies.
If you have a 2.3L, 2.5L or 5.0L engine model, you may find two separate coil packs installed. Look at the front, upper and left hand side (driver’s side) of the engine. Alternatively, just follow the spark plug wires from the spark plugs to the other end of the wires. Unplug the coil pack assembly electrical connector (s).
How can I tell if my Ford 4.6L ignition coil is bad?
There are several ways to find out if the COP ignition coil on your Ford 4.6L or 5.4L is BAD or not. One is using a spark tester and is the most accurate way of testing for a BAD Coil-on-Plug (COP) ignition coil.
Plug the spark plug wires into their corresponding terminal towers on the coil pack assembly. Attach the EGR vacuum regulator solenoid to the coil pack mounting bracket, if necessary, using the ratchet, ratchet extension and socket. Plug in the coil pack assembly electrical connector (s). Connect the negative battery cable using a wrench.
