What are the codes for the ignition coil?
If your vehicle’s computer detects a problem in the ignition coil circuit, it may send the ignition coil circuit codes P0351-P0358. The last digit of these codes refers to the cylinder where the issue is located. Repair and diagnosis procedures might differ according to the cylinder.
What causes a p0351 code on an ignition coil?
In some cases, the insulation of the coil gets damaged, causing a short. In other cases, the problem stems from bad spark plugs and wiring issues. The P0351 code may appear when your car’s primary computer, which is often referred to as the powertrain control module (PCM), perceives a problem with the cylinder #1 ignition coil or its circuit.
How to check primary circuit resistance on ignition coil?
Attach one lead of your multimeter to each terminal on the coil and set the meter to read ohms. This tests the coil primary circuit; typical readings should be 0.4 to 2 ohms. Consult the manufacturer’s repair information for the exact specifications. Next, check the secondary circuit resistance.
Where are the spark plugs on an ignition coil?
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.
What is the diagnostic code for ignition coil C?
P2308 code definition. The P2308 diagnostic trouble code is an indication that there is an issue with the ignition coil C secondary circuit. Related Trouble Codes: P2300 OBD-II Trouble Code: Ignition Coil A Primary Control Circuit Low.
What is the ignition coil code for a Jeep Grand Cherokee?
Jeep Grand Cherokee 4.0L straight 6 were given the codes P0351, P0352 and P0353! I change the ignition coil, Crank sensor, cramshaft position sensor, sparks plugs, injectors!!
What does ignition coil B primary circuit malfunction mean?
Ignition Coil B Primary/Secondary Circuit Malfunction What does that mean? This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model.
What’s the ignition coil for a Ranger 3.0 engine?
05 ranger 3.0 engine.. code P0352. very weak if any fire on # 3 & #4 cylinders, changed two new coil packs (same results) new spark plugs (same results). new plug wires (same results) 60psi fuel pressure, cleaned MAF, put test light on lead going to computer to check for trigger, lights flashes….
What causes the coil on the spark plug to fail?
Your vehicle’s ignition coils provide the high voltage needed to ignite the spark plugs. Most modern vehicles have an individual coil-on-plug ignition coil for each of the engine’s cylinders. Ignition coils can fail for a variety of reasons. In some cases, the insulation of the coil gets damaged, causing a short.

Can a misfire be a missing spark from an ignition coil?
The reality is that a misfire can be more than a missing spark from an ignition coil. Misfires that are below the vehicles threshold often pass unnoticed, but a constant misfire is hard to be overlooked by you or the engine management system.
