I've been dealing with this problem for a while. Rainy weather causes error codes p0340 and p0320 on my Dodge Dakota 3.9l V6. Yesterday check engine light comes on (again) but (for the first time) it would not start after I had shut it down. Next morning, starts right up and allows me a 30 mile trip home. Now it will run sometimes...
Before computers, I would've done rotor, cap, wires and plugs. But it's 2010 so I'd like to address these sensor issues as well. One of them (the camshaft position sensor) is under the distributor cap and just below the rotor. No problem there. But where is the Crankshaft position sensor?? And is the fix as simple as dropping in the new sensor and hooking it up? Or have they managed to block out the at home repair be requiring a computer connection?
