ok this car is really starting to piss me off i just was having problems with the crankshaft sensor keep failing so i replaced it and now i throw another code of Crankshaft Position Sensor A Circuit Malfunction so if anyone has any ideas for what i should do on this one also let me know or had the same problem and fixed it plz let me know thanks

 

no clue on that one......did you just buy it?

 

i bought it awhile ago like 2 and a half months ago

 

make sure none of the wiring was stripped and touching anything. also check to see if its a stage 1 or stage 2 ecu. they tend to throw stupid codes for no reason

 

sounds llike wires broken or maybe reversed...

 

so about that hood............lol

 

yes, sounds like the sensor was fine, you have to do a little wiring harness investigation. do you have a shop manual or wiring diagram? if not PM or call me, I can help. 813-333-1100. if a dealer finds a dead short in your harness he's gonna want to replace the harness, so to fix it on the cheap, run some new wires or bring it down and I'll check it out for you.

 

Check the harness that goes around the head under the manifold to the sensor. They tend to wear and short things out. Also sometimes it's not the CPS but CMpS (cam sensor). The run on the same circuit and could annoy one another. I would definitely check the harness though..I have never heard of a staged PCM throwing random codes for no reason.

 

Check all your spark plug wires and the plugs themselves. Pending on the manufacture date some of the plugs and wiring can be faulty. and cause other issues to arise making it seem like something else.

Any plug or wire that is faulty will cause a misfire in a cylinder if your having idling fluctuation.

let me know what you find

 

i had the same problem with my sxt..
i took it to the dealer and they fixed it.. they said their was a shortage in the wireing system.. it suckz cuz i paid 100 bucks for them to do it..
