Talking 2302 help

I have an 04, 2.4 106000 miles. I have a new coil pack, crank shaft sensor at 90000. Plugs and wires at 82000. Cam shaft sensor at 68000.
Now I have a 2302 code. Help. Please

P2302 code. This code is for coil #1 Insufficient Ionization. This is a very common code on Chrysler vehicles. On this Chrysler style ignition system the Automatic Shutdown relay supplies battery power to the positive side of the coil. The voltage flows through the primary windings of the coil out the coil negative terminal back to the PCM. The PCM is the ignition module and responsible for primary triggering. This code sets when the PCM does not see proper primary events.

You might want to double check the connector for coil #1 that the coil connector plugs into. I had another member that found that connector was bad, went to a junk yard and found another one to replace it. It fixed the problem.

Has your timing belt been replaced on this PT Cruiser? The camshaft and crankshaft error in degrees is another area to look at that might be causing the P2302.

Please post what you find out.

Timing belt and water pump was changed out at 72000.
If I used a plug in diagnostic instead of the key dance would I
maybe get additional codes?
My plugs/ wires are 30000 miles. I will replace them first.
After the Tow dropped off the car I had to back it into the garage about 30 feet. It started and it ran really ruff. There was also a funny smell. Not tranie, not A.F. not oil.

If it smells like rotten eggs then its possible you have raw fuel getting to the CAT and that is what it smells like coming out of the exhaust.

The major point of getting an OBDII Scan Tool is to reset the diagnostic trouble codes. I also like using it because I will know for sure what codes its triggering and not wonder if I missed any codes using the key dance.

After New Plugs, wires and coil (only 13000 on the coil) it seems to drive around the block . OBD11 is clear. No more codes. I will be driving it today. I can see the plug going bad. I had life time wires. The coil being replaced once ok. But twice. ? We did the work. Hopefully it was 123.00 well spent.

What was the reason the coil was replaced the first time?

How did the spark plugs look when you removed them after putting 24,000 miles on them?

The coil wasnt putting out enough. The service station said that it could be the reason why I was blowing sensers.
The plugs were gapped at 50 when installed. Came out at 80.
The replacements were already set at 50
The electroid that should be flat was totally round and pointy

Gap should be .40, it's no longer .50 it was changed in a service bulletin.

The recommended gap is .042.

The reason most members use the gap reference .040 is because the most commonly available plug gaping tools are not set for .042. So many really take the easy way to gap their spark plugs at .040. Then with many members using the easy way to gap at .040 they would recommend the gap being .040 instead of a better .042 optimum gap setting.

That's why I edited .42 out of my reply.
