Dodge durango 3.6vvt coil 2 locad code#

I read the codes with an ODB2 Reader and I was getting codes P0302(Cylinder 2 Misfire Detected) and P105D(Intake Valve Stuck in High Lift Position). The problem that I was having was that the engine was sputtering and one cylinder was missing at low speeds/rpm. My Jeep was in the shop for a month and a half and they couldn't diagnose the misfire problem that I told them was most likely caused by the VVL Solenoid. Military in Germany so I took my Jeep in for repair at the local dealer here. I had the same issue at around 100,000 Miles.

Our Favorites Sites If any of the injectors read outside of the specified values, they will need to be replaced.Īlong the same lines, a fuel pump starting to go bad can also cause misfires or similar issues and can be diagnosed with a fuel pressure check of the entire system with the appropriate equipment. The mechanic disconnects the injector, then touches the multimeter probes to the two connector prongs to read the value, in Ohms. It may be a bit difficult to reach them, sometimes requiring the removal of an engine cover and the intake manifold. A mechanic uses a multimeter to check the resistance value at each injector. If it isn’t an ignition issue, then the injectors will need to be checked. If a new spark plug at that cylinder does not remove the stumble, the mechanic may need to replace the coil pack or the wires as a set. That will suggest that it’s either the spark plug or the coil serving that cylinder at fault. Most removals will cause a profound change in idling performance, but a defective wire will not. One way mechanics check which spark plug is failing to hold its own is by running the engine at an idle speed high enough to produce the misfire, then removing leads from the coilpack (the unit that looks like the distributor we are used to seeing in older vehicles ) one by one. Checking them in the dark will sometimes reveal errant spark tracking, as will spraying them with a fine water mist. As with older vehicles, a look at the wires and spark plugs is a good idea.

It was part of the push toward cleaner exhaust emissions.Ī code reader will tell you which cylinder is to blame, but it may not say whether it is a problem relating to the injector serving that cylinder or the systems delivering the ignition spark. government introduced the rules for OBD-II (on-board diagnostics, second generation). In fact, checking for efficient combustion was the primary reason the U.S. In modern cars, misfiring will invariably be accompanied by a Check Engine light. The next step would be checking the wiring to that plug for cracks and deterioration, and replace as necessary. If needed, the spark plug can be replaced. The guilty plug will most likely be grayer than the others, which should tend toward brown coloring. The first thing the mechanic will do is determine which cylinder or cylinders is misfiring, and the spark plug color is probably the best way to tell. A vacuum leak or a faulty fuel pump can also cause this symptom as well. On older, carbureted vehicles, the culprit will almost certainly be in the ignition system as older vehicles lack many of the sophisticated sensors that can cause a misfire. Not all misfires occur across the operating spectrum.

It can be tricky for to track down the problem if the misfire only occurs under certain circumstances, for example, under load. It is accompanied by a loss of power in direct proportion to the severity of the misfire.

When an engines misfires, it’s usually readily apparent to the driver from the stuttering and jerking produced by the engine when one or more cylinders fails to fire properly, either because of ignition- or fuel-related issues. Service type Engine is misfiring Inspection
