SOURCE: code p2305 ignition coil b

The wire for the secondary on that particular circuit has to be tested If you have a ICM that secondary has to be tested there, If it is controlled from ECM it has to be tested at the ECM, because its a secondary wire it is capable of shorting the ICM or ECM it self, you only listed the year and.no engine size.

Ouch! A case of the raucous rodent! I've been there...Not fun trying to track down and repair all the damage.

First of all, let me explain how the code sets: The computer monitors the PRIMARY side of the coil to determine the burn time on the SECONDARY side of the coil. This can be a little confusing. The code will set when the computer determines that secondary ionization (burn time) was too short, too long, or did not occur at all.
If you have confirmed that there is no spark at the spark plug wires, then that is why the code is setting...ionization is not occurring at all. What can be a little confusing is that this can be caused by a failure in the PRIMARY coil circuit even though the code is indicating that the computer is having a problem with the SECONDARY circuit. (The secondary circuit can malfunction even though the primary side is functioning perfectly, but if the primary side malfunctions, the secondary side ALSO malfunctions - it is impossible for the secondary side to work if the primary side is not working.)

So, I said all that to tell you this: I think you have pretty much eliminated the entire secondary side of the ignition by replacing the whole circuit. So the problem must be on the primary side. (Probably more chewed wires)
There are 4 wires going to your ignition coil. The BROWN/WHITE wire comes from the ASD RElay and supplies battery voltage to the coil assembly. Since the other four cylinders are firing, This wire has to be OK.
The code you are getting is for coil #2. This coil is controlled by computer through the DARK BLUE/TAN wire. If you disconnect your coil connector and probe this wire with a test light connected to the POSITIVE battery post, it should "blink" when to crank the engine over. My guess is that it will not be blinking. You can do this also on the BROWN/ORANGE (coil #1) wire and the DARK BLUE/DARK GREEN (coil #3) wire to see the difference.

Anyway, if the DARK BLUE/TAN wire does not blink, then the wire is broken (chewed?) between the coil and the PCM.

i would start by checking plug wires and spark plugs for proper gap replace if necessary check for compression in all cylinders i dont know what your codes are

What does the diagostic code p2305 nean


P2305 - Coil #2 Secondary Circuit Insufficient Ignition Ionization
As to the fix, well it can have multiple causes, a bad PCM, a bad ignition coil.

Got 2004 dodge stratus misfiring code says p2305 already changed coil and spark plugs and wires still misfiring


Who is doing the parts replacing?

Have you looked at Scan Tool Data & road tested?

Have you actually done any testing, to find a problem
& used the codes to component test

Till you answer that, I will say you need a repair shop

Lots of things cause misfires

Changing spark plugs & a coil or two ,based on a code,
is not doing the required testing to find a problem or the
need for parts just yet

2004 dodge dakota in limp mode wont go past 2000 rpm P2305 code comes on check engine light comes on can reset code but light stays on and wont go past 2000 rpm


Since you didn't say what engine you have, I am assuming it to be a 3.7 L. Code P2305 is set for insufficient ionization of the #2 coil. 1. Inspect the spark plugs for correct application, these should have NGK platinum spark plugs installed. Inspect the plugs for any signs of misfiring, such as carbon tracking on the spark plug insulator or the coil boot. Inspect for cracked spark plugs or incorrect gap. Inspect for any kind of fouling on the spark plugs. Replace the spark plugs or the coils as needed.

2. Verify the wiring is not shorted to ground from the coils to the Powertrain Control Module (PCM).

3. Keep in mind that anything that can affect the air fuel mixture can cause this code to set. Be SURE that there are NO vacuum leaks, the injector is not at fault, etc. Moving parts one at a time (spark plug; coil; injector) to "known good" cylinders is the best way to diagnose this trouble code.

Hi A Vig, I'm glad to help! P2305 is a Secondary Ignition Circuit problem that will cause the Misfire code P0300. Sounds like you have already replace everything that would cause the P2305 code. Sense it's a circuit code, there is always a possibility that you could have a wiring issue. One place to check is where the wire lume runs over the front of the transmission. We've seen wiring issue here at the dealership a lot in that area. Check and see if any wires are frayed a shorting out, and also check the connector and wiring at the coil pack itself. I've found a broken wire there before. Also you might swapping the ASD Relay with another one that looks the same to see if it may be the relay thats defective. Hope this helps and have an awesome day A Vig!
