Why is my Lincoln Town Car getting misfire codes?
Why is my Lincoln Town Car getting misfire codes?
If you find that the engine isn’t misfiring, the coil is being triggered properly but P0353 is continually being reset, there is the possibility that the PCM coil monitoring system may be faulty. 2005 Lincoln Town Car 4.6L engine having Coil On Plug (COP) ignition I’m getting misfire codes on the entire right (passenger) bank.
What causes the ignition coil C trouble code?
A pulsing ground is supplied by the ECM, which activates the ignition spark and controls the ignition timing. If the voltage in the ignition control circuit for ignition coil C varies by more than 10% from allowed parameters, set by each automaker, a malfunction is noted and a P0353 code is stored. What causes the P0353 code?
What are the symptoms of a p0353 ignition coil C?
If an open or a short is detected in the driver circuit for coil number 3, a P0353 may set. Also, depending on the vehicle, the PCM may also shut down the fuel injector to the cylinder also. Symptoms of a P0353 DTC may include: MIL (Malfunction indicator lamp) illumination Engine misfire may be present or intermittent
What is the misfire code for cylinder 3?
Code P0353 is a misfire code for cylinder 3 and replacement of the plug and coil means that the problem is unlikely an ignition system component.
If you find that the engine isn’t misfiring, the coil is being triggered properly but P0353 is continually being reset, there is the possibility that the PCM coil monitoring system may be faulty. 2005 Lincoln Town Car 4.6L engine having Coil On Plug (COP) ignition I’m getting misfire codes on the entire right (passenger) bank.

What to do if ignition coil is misfiring?
If the engine is misfiring presently, stop the engine and disconnect the #3 coil wiring connector. Then start the engine and check for a driver signal to the #3 coil. Using a scope will give you a visual pattern to observe, but since most people don’t have access to one there’s an easier way.
Why is my ignition coil not turning on?
It’s likely bad. 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.
