I have a 1999 durango, I have replaced the governor pressure solinoid and switch. I also replaced the PCM for a no bus problem(I went through all the ideas everyone had on here, then I noticed if I moved the hard plastic plug on the PCM all my relays would come bake on line). I am now getting the P1757 code again for the governor pressure over 3psi at 0 mph, and now my fuel gauge sits on E. If i unplug all three plugs on the PCM and plug them back in then it will show full, it will not show how much is actually is in the tank.I also have a p0505 code which is IAC fault this is the third IAC motor I have put on, maybe its a mexizone (autozone) issue. If you can help me I thank you in advance. Also I'm a new member here and have found this place to be very helpful. Thanks

 

This is with a replacement pcm? is it under warr? If so I would exchange it.

First of course check that pcm connector for damage. sometimes forcing the plug can pop a connector socket out of the housing.

If the sockets look ok, Napa should be able to get you some stuff called stabl?? the question marks will be replaced by numbers I can't recall right now. its good for fixing iffy connections but it ain't cheap. comes in a eye dropper bottle in a tube. They will have to order it.
Take it one at a time sort out the pcm issue first then look after the trans issue. check your grounds.

 

Thanks I went through the whole truck and could not find a problem with anything. I traced it all back to the PCM, and went back to Dodge house. After two days of diag. they finally reached that it was the PCM and I'm waiting for them to get it, so I went and bought a brand new CHEVY!!! But I will keep the dodge for family trips. Thank you for your input.

 

Trader!.......

 

Hey man 34-38 mph (cobalt)sounds a lot better than 12-13 mpg, but I still love my durango it's a lot of fun.

 

Traitor??? Who switched from a D to a Ram???
I kid!!! I kid!!!

 

no he doesnt, dont let him fool you

 

At least I stayed with Mopar, but yes I'm a traitor to the Durango.

 

true, you do get at least some credit for staying mopar

 

Hey! Who's the one always busting hydra's chops about the switch? Not me.....
