engine trouble codes

Q: elijahs@gmail.com wrote ok heres the deal 1999 durango v8 64k miles intermittent engine + guage failure; odometer reads no bus. the fix is i go and press on each of the three pcm connectors and at some point the whole thing comes back to life. no heat correlation and its really easy to get it going again. when this happens the odb codes get reset but there arent any codes being recorded i know the codes are being reset because some of the tests that only complete once youve driven a while show as incomplete again after the error occurs. finally - its a friends backup car but her parents are coming to town and this just started happening. id like to save her a bill at the dealers. is this definately the pcm and therefore covered under the 8/80k warranty i pulled all the connectors and sprayed everything down with electronic cleaner; didnt really help anything. sometimes the jostling of the engine trying to start actually fixes it. any help terribly appreciated! elijah electronic cleaner !!! what the heck is it some of that stuff will do more harm than good. jam .

on position and i received a code that was c code 23 97.... any input would be great thanks...mars.. according to my 94 - 01 haynes manual says this code applies to 94 - 97 23 - intake air temp sensor input is out of range either high or low no - the c codes are cluster codes. remember that the 02 1500s are 3rd gen trucks and the instrument cluster runs just about everything in the cab. this particular code 23 is a headlamp switch input circuit open and it happened 97 ignition cycles ago in other words its a nuisance code - ignore it the p1491 code indeed refers to the cooling fan relay control circuit. ah yes! sorry i was thinking br/be....my mistake thanks tom. -- ---------------------------- -chris 05 ctd 06 liberty crd real trucks dont need spark plugs. .
