suddenly without warning dingy101 exclaimed 12/24/2008 910 am 2003 dakota 3.9 auto air wont start this morning cranks but doesnt fire what do codes p0320 p0138 & p0455 mean. thanks gary dinges garyatdinges.com dont know about the other two but i believe p0455 is the one that can pop up if 1. you dont crank your gas cap on correctly. i think though that the codes attempt to clear every x 10 starts so if this has been there for a while or you clear the codes and this returns it might be 2. your gas cap is defective - easy to replace. if you do that and the code still comes back then perhaps 3. you have a damaged vacuum line at least i think thats what ended up being wrong in mine. jmc .

would the p0320 possibly be a defective crankshaft position sensor yep sure can. thats one of the possibilities listed in the fsm among others cam position sensor signal intermittent crank position signal 5-volt supply circuit shorted to voltage 5-volt supply circuit open 5-volt supply circuit shorted to ground ckp thats the crank sensor sensor signal circuit shorted to voltage ckp sensor signal circuit open ckp sensor signal circuit shorted to ground ckp sensor signal shorted to 5v supply sensor ground circuit open crankshaft position sensor pcm youd need a wiring diagram to troubleshoot any wiring shorts and whatnot but if you want to roll the dice and just swap the sensor its on top of the transmission bellhousing passenger side and is reachable through the passnger-side wheel well by removing the tire and the plastic inner liner. having removed this from a 00 durango several times been arguing vociferously with a transmission for the last... well a while i can tell you that a 1/4+ drive 1/4 allen socket with a short 2-3 extension and small 1/4 ratchet is the best way to remove the sensor. the sensor sticks into the bellhousing a good amount maybe 5 so its a bit of trick to wiggle it out but not impossible. before buying a new one disconnect the wiring and with the ignition on check for +5v at the connector on pin #3 and ground on pin #2. if you dont have +5v or a ground then youve got a wiring problem and need to track that down. .
