I have a 2003 Durango 4.7 4wd and have had issues with cylinder 5 misfire for the past three years I have replaced coil packs and plugs so many times I have the tools in the glove box along with a plug and coil. A friend of mine had the same issue on a caravan told me to change the Crank Sensor that was his problem.

I changed the crank sensor after having to torch the old one to free it from its home. it was hard to start took three times then when I get to 32-3500 RPM it acts like it hits the rev limiter. I took the positive off the battery and held the key for 30 seconds to reset the PCM but no change. For those that say you just need to drive it I put 600 miles on this weekend.

I got the sensor at AutoZone I think it is a BWD brand.

codes are p0339 and p0305

 

You want a mopar sensor.

 

I was afraid of that I have already looked up the price of them they average $80.00

 

Yeah, expensive, but, they actually work right.

 

I was online looking for the sensor and seen one at NAPA for $36.00 and it is listed as OEM I think that I am going to try it first. I have had pretty good luck at NAPA for oddball things

 

What brand part?

 

UPDATE...….
I bought the one at NAPA last night and it worked
