Lincoln P0361 Ignition Coil 11 Primary/Secondary Circuit Malfunction

Description

OBD-II Trouble Code Description for P0361 Lincoln

Ignition Coil “K” Primary/Secondary Circuit

What does this mean?

OBD2 Code P0361 Lincoln definition:
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. Two wires are dedicated to each coil. One is a battery feed usually from the power distribution center. The other wire is the coil driver circuit from the PCM. The PCM grounds/ungrounds this circuit to activate or deactivate the coil. The coil driver circuit is monitored by the PCM for faults If an open or a short is detected in the driver circuit for coil number 11, a P0361 Lincoln may set. Also, depending on the vehicle, the PCM may also shut down the fuel injector to the cylinder also.

Symptoms

Possible sumptoms of OBD code P0361 Lincoln
MIL (Malfunction indicator lamp) illumination Engine misfire may be present or intermittent

Causes

Possible causes of OBD code P0361 Lincoln
Short to voltage or ground on COP driver circuit Open on COP driver circuit Loose connection at coil or broken connector locks Bad Coil (COP) Faulty Powertrain Control Module

Possible Solutions

Is the engine misfiring presently? If not, the problem is likely intermittent. Try wiggle testing the wiring at the #3 coil and along the wiring harness to the PCM. If manipulating the wiring causes the misfire to surface, repair the wiring problem. Check for poor connection at the coil connector. Verify the harness isn’t misrouted or chafing on anything. Repair as necessary 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. Use a Voltmeter in AC Hertz scale and see if there’s a Hz reading of between 5 and 20 or so that indicates the driver is working. If there is a Hertz signal, then replace the #3 ignition coil. 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. If there is any significant voltage on that wire then there is a short to voltage somewhere. Find the short and repair it. If there is no voltage on the driver circuit, then turn the ignition off. Disconnect the PCM connector and check the continuity of the driver between the PCM and the coil. If there is no continuity repair the open or short to ground in the circuit. If continuity is present, then check for resistance between ground and the ignition coil connector. There should be infinite resistance. If there isn’t, repair the short to ground in the coil driver circuit NOTE: If the ignition coil driver signal wire is not open or shorted to voltage or ground and there is no trigger signal to the coil then suspect a faulty PCM coil driver. Also keep in mind that if the PCM driver is at fault, there may be a wiring problem that caused the PCM failure. It’s a good idea to do the above check after PCM replacement to verify there won’t be a repeat failure. If you find that the engine isn’t misfiring, the coil is being triggered properly but P0361 Lincoln is continually being reset, there is the possibility that the PCM coil monitoring system may be faulty.

Note:

1. The list of automotive Makes at the right edge of the screen. The currently selected ODB-ii codes is for the Lincoln makes.

2. Look up the other OBD II Trouble Codes, please use the search box. Enter the 5 character trouble codes in the search box and submit the search.

3. Don’t assume a particular OBD-II code means the same for other auto manufacturers as there are many makes specific codes in use.

4. If your OBD-II trouble codes are for a different car, select that vehicle series before searching for the diagnostic codes because not all OBD2 codes used by one manufacture are used by the other makes.
