The crank sensor input voltage is 5 volts. the engine code is po344,cam signal.where do I go from here?
Both crank and cam sensors have a 8 volt reference I have found the wiring melted together where it cross over transmission shorting out the signal. also test your reference voltage at the computer with circuit unplugged at sensor watch meter and wiggle wiring going back to computer this will help find faulty area.
I pulled the plugs on the cam & crank sensors and also the wire harness plug from the computer. Then I put 12 volts on the supply wire on the crank sensor harness. I prodded all of the wires at the computer harness end. I had continuity at only one point with no bleeding to any other wires. I did the same for the cam sensor then I put on the supply side of the crank harness and chedked the wire loom for continuity and it was fine with no bleeding to any other wires. I then found the wire that should have had 8 volts supply to the crank and cam sensor in the computer. With the key on I only had 5 volts no harness connected. I'm now thinking I have a bad computer, unless could I have missed something.? Thanks. Help Greg
I'm taking it in to get the computer resyncronized with the cam and crank sensor at the dealer , we'
I'm taking it in to the dealer to get the computer syncronized to the cam and crank sensors, we'll see how that goes . I'll report the findings Thanks Greg.Add a Comment

hi greg check our gaz pressure i lock forward to it will find the problem have a good day from montreal canada pierre

My thought is to get a refund from the shop that tried to replace parts in order to secure your problem. The job of the shop is to diagnose the problem, not to replace items that may be the problem. Chrysler Master Techs are not trained to just replace parts, they fix the problem by diagnosing it properly.
You need to see a Chrysler dealership so they can attach a DRBIII and tell you exactly what is at stake.
I hope this helps you. I would be mad as heck.
I would not think the plugs and wires would be the problem because they would all have to fail at the same time to provide the symptom you experienced.
1. Get your money back
2. DRBIII
SOURCE: how do you test the crank and cam sensors on 02
TESTING OF CRANK SENSOR
Normal resistance is 200ohms, +/- 75ohms.
275ohms to 125ohms...any higher or lower and it is recommended for replacement.
MAP SENSOR TEST

theres a reflash program that needs to be done on these cars, because of extended crank time and cam / crank syhcronizing out, start there,also i had one with same code and found that aftermarket cam sensors dont work, installed dealer part and had the updated reflashing done and solved the problem.
SOURCE: 3.5l engine, car shakes
the chances are good for the number 5 coil needing replacement, but before i did anything else i would change that cam sensor, that could be causing your problem all the way around.. hope this helps... setting timing is a big drawn out job, i dont think you will need to do that, timing shouldnt be out.

I pulled the connectors off thecam &crank sensors,pulled the wire harness connector
I am sorry Greg this code is a synchronization problem. The computer reads that the engine is cranking by crank sensor pulses but does not see the cam shaft sensor pulsing voltage high to low and back a logic probe on signal return wire can test this with a signal LED it should flash yellow on a dual red and green should both flash alternating you can remove sensor and manually toggle sensor with a strong magnet waving it across sensor and watch logic probe.
