You have two unrelated problems. The computer doesn't like your cam position sensor - replace that sensor. There also seems to be a problem with your evac pump, which may be a lot harder to track down; you may have a problem with the pressure switch or with a vacuum leak or vent leak somewhere within the fuel-tank-to-charcoal-canister-to-engine lines. Try replacing that switch first. If that doesn't fix the problem, then you'll need a hose routing diagram - with it, trace the vacuum lines and vent lines, looking for leaks or blockages.
P0340: Camshaft Position Sensor A - Bank 1 Circuit Malfunction
- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
- Faulty Camshaft Position Sensor
- Faulty starter motor
- Starting system circuit
- Dead (Weak) battery
This could be related to a loose camshaft drive belt. If you have slack in the belt the camshaft will rebound on over run causing the P0340. It can also be a Crackshaft sensor problem too.(P0335)
Hope this helps...
they can run with out a cam sensor but they will not run with out crank signal i would check for crank signal it may not throw a dtc because it wont start.
Change the camshaft position sensor AND the magnet with mopar (dealership) parts ONLY. You can change just the sensor but 9 times out of 10 the code will come back.
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.
change the crankshaft positon sensor in the rear of the engine above the oilfilter. Also check the wiring to this sensor, they have a problem shorting out. You have to change the camshaft and crankshaft sensors at the same time. Make sure you give your car a major tune up. Did you check yor starter?.........runjoe
