What does D mean on Ford Escape ignition?

Which means that plugs, plug wires (if so equipped) or the spark plug itself is causing your Escape 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 causes Ford Escape to throw SPARK code?

The primary wiring is the wiring harness leading from your Escape’s ECM/PCM to the ignition system itself. A short, open, or poorly ground wiring harness is almost always what causes P0354 when it is the primary wiring side that has thrown the code. The secondary side of the equation is the spark side.

What is the OBD2 code for Ford Escape?

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 Escape has thrown this code, it may be accompanied by P0304.

Is the spark plug part of the ignition system?

Something else is going on, and there is a very strong possibility it is with the ignition. The ignition system is considered to be passive. The spark plug only takes from the ignition coil what it needs to create an arc across the plug’s electrodes. It must be recognized that ignition demand is determined by the following:

Can a spark plug be covered in oil?

This is bad for both the ignition coils and spark plugs as it can cause misfires, and it can also cause these parts to fail. If your whole spark plug is covered in oil, you should definitely replace the valve cover gasket and the O-rings around the spark plugs.

Why does the spark plug arc when the engine is idle?

This is due to the throttle being almost closed, the engine rpm being low, and the fact that there is no load on the engine. If the engine was still idled and a load was gently applied (engaging a PTO, for example), the voltage required to arc the plug would increase dramatically.
