Default 2007 Cruiser P0340 / P0522 Combination

Howdy! New to me PT, 124k. Last night MIL came on, P0340, Limped home no problem. Replaced Cam position sensor today with Mopar part, now will not start, cranks fine, and have a oil pressure code added. Suspect a brittle wiring issue, doubt the sensor just decided to quit sitting in the garage. WIring harness plastic coverings all brittle and crumbling. Cam is turning fine so timing belt is still there. Put old cam sensor back on and still no start.
Now I do not appear to have spark at the plugs.
I only see one wire to the oil sensor, yellow, assume it goes to PCM? I have good light and visibility and do not see any obvious worn insulation. Will check voltage to coil pack.

Thanks troops

I'd take a look at the crank sensor. If it were cam sensor related, you can simply unplug that and the car should still start. It just will have a longer crank time before it does start. But, I'm not a mechanic and don't know anything.

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

P0522 - Have you checked the engine oil level?

Thanks folks. I now do not have spark, no 12v at the coil pack which started after replacing the cam sensor, it was running previously. Tried to check voltage and signal at crank sensor but it's a bitch to get to the connector so I'm replacing it today. Starting to suspect a 5v problem, perusing wiring diagrams now.

Yes, with key on I have 5v on the cam sensor lead 1, center is 28 ohms to ground and if I run a magnet past the sensor I get a relay to click then lead 3 goes from 0v to 5v, the signal.

3 hours to get the crank sensor out, had to pull the starter and the damn sensor housing broke off inside the block, just got it out now, done for the day.

New day, new attitude. crank sensor replaced, have 5v power, 27 ohms to ground at ground lead, 0 to 5v on signal lead when running a magnet past the sensor. Same results at the new cam sensor.

Definitely do NOT have 12v at the coil pack while cranking, and now NO codes.

Just going to keep adding info, maybe help the next person.

Fuse 23, 15 amp ASD relay feed 3 is blown and continues to blow. Off in a new direction now looking for a wiring diagram. If ASD can't pick, no 12v to coil and injectors.

Might be a stupid question, but what happens when you put the old cam sensor back in? I might have read wrong, but if it started with the old sensor, but wouldn't with the new, perhaps you got my luck and a bad sensor?

Howdy, learned long ago servicing IBM equipment for many years, one step at a time, take a step back when things change. I did immediately try the old sensor. Here's the scoop as of last night;
Got it. There is a radio noise capacitor attached to the block kinda below the PCV valve, various sources said it is radio only, ignore it, run wire to ground without the cap etc. It was broken, not readily available, grounding that wire without the cap blows fuse 23, no 23 no ASD, no 12v to coil and injectors. I was able to epoxy and solder the cap back together and it reads ok, (.47 uf stamped, reads .51 uf) . Starts fine now. Surges under load if you floor it and no codes posted or pending.

Will give it a set of plugs and wires, continue with the front suspension rebuild then drive it and see if it develops codes if plugs and wires didn't fix the surging.
