I have a 2001 Dodge Dakota Quad Cab Pickup with a 3.9L 6Cyl, Automatic transmission, 102,500 miles. I bought the truck about a year ago from a friend in our neighborhood (the original owner).
The truck runs great, but on humid or high moisture days my truck starts throwing PCodes. It will start by throwing a P0152 and then later throws a P1740. The next day the check engine light will turn off and I check the PCodes and they are gone. The truck runs great again! Sometimes if I disconnect the negative post and turn the ignition to on and then off to clear the computer and reconnect the neg. Post the truck runs great again. What is going on? The transmission seems to be strong and will climb a steep hill with no problems (also accelerates up the hill). There is no slippage in the tranny.
This past week on a extremely humid day, the truck disengaged the Overdrive and switched the transmission into 3rd. I limped home and the next day I started the truck and it was fine again.
On days that the temperature is below 45 degrees F, the truck runs like a new truck. I spoke with some of my Dodge Truck friends and they seem to think that I need to pickup some electrical paste and coat the connecters on the computer / wiring harness. I don't understand what is going on. Is my computer getting ready to die? Can you shed some light on this mystery?
