Welcome to the forum

Do you know if the timing belt has ever been replaced on your PT?

Please go to: Welcome New PT Cruiser Members - PT Cruiser Forum introduce yourself and tell us about your PT

I think he did just introduce himself. His name is Daybreak12 and he has a 2005 PT with a manual trans and 94K miles with some issues.

It sounds like you may have an ignition related problem. The rough running can often trigger other codes that aren't necessarily defects, as you found with the sensor you replaced, but the code came back. Have the plugs and wires been changed? Usually when you have original wires after this long and so many miles, they are not working well anymore. You will probably notice a big change with replacement wires if they haven't been changed already. Often when the ignition coil fails, it doesn't actually trigger a code. These cars tend to be a bit fussy with replacement coils.

Do you live near a serve yourself junkyard? If you have a pick a part or whatever name those yards go by in your area, you can often find relatively new wires and coil on any Pt Cruiser or Dodge Neon. That's what I did. I got a nice set of newer NGK blue wires and a coil for next to nothing from a Neon.

I think it depends which code came back. If it was the misfire, then the ignition would be my first suspect. If the 344 came back after changing the sensor, my first choice is the wiring to the cam sensor. Check the connector and then follow it back.

The 3000 rpm jerk and miss sounds like cam sensor to me. They are like an on/off switch when you hit that rpm. I think it is a failsafe. If the new sensor didn't fix it, my next steps would be the wiring and checking if the magnet cracked. I think some hamfisted mechanics <cough, cough> over torque the sensor which can crack the magnet. I've never seen it in practice, but I've read it here a few times.

Good luck

Ever since Rob made a comment a while back on new members immediately posting their issue, and everybody pouncing in to give them a welcome, several members, including myself, encourage that new member to first create their intro thread in the New Members section, to get all the welcomes over with in that thread, then on to solving the issue.

I have to say, that it has worked and I believe that CREWZIN, if he is keeping track, has seen an increase in the intro threads.

P0344 - Camshaft Position Sensor Circuit Intermittent Conditions

Possible Causes:

1. Wiring harness fault 5 volt supply circuit open or shorted to ground
2. Tone wheel/pulse ring is damaged or corroded
3. Camshaft Sensor has failed
4. Camshaft Sensor signal circuit is open, shorted to ground or battery voltage or 5 volt supply
5. Camshaft Sensor ground circuit is open
6. PCM has failed

Was the target magnet removed lately? The target magnet is very easy to crack and there has been warnings about over tightening it.

Just a quick FYI. I replaced my cam sensor at around 100k miles. The first one I bought was an aftermarket. It did NOT work. I bought an OEM sensor and it DID work. I just replaced the cam sensor again at 172k and I decided to give the aftermarket one another try. So far, it is working fine. So, I'm guessing if you bought an aftermarket sensor, you may have gotten a bad one.
