I have been reading a lot of of different things on line about this year truck.
Being a Chrysler fan, I purchased this low mileage 2006 Dakota (76,000 on Odometer) in December.
Great running little truck.
With out going into a lot of detail based on this year truck having computer issues. I inherited this problem. I brought the truck to a great mechanic who helps me with my company vehicles and extraordinary repairs.
He has had the the truck for a month and has called me once telling me he had to track down a computer. I told him to proceed based on knowledge I have read.
He is dedicated and will try to solve this.

I am coming to Moparts to help me with this Dakota Dilemma. Can someone please tell me what the problem is with this truck regarding engine light, like limp mode, correcting itself, then coming back.
I can then let the mechanic know which way to go.

Well if you told us what codes you are getting that would be a start as well as what symptoms there are, all of them even if it isn't engine driveability related.

This is a well known problem for these trucks for the year. I don’t know what codes, but all other discussion boards are stating consistent codes.

I was hoping that someone had chased this or a Chrysler mechanic member has a resolution on this issue regarding the computer.

If it fixes itself, but then the problem comes back, I would start by looking at the wiring for broken or frayed wires or faulty sensors. An intermittent vacuumed leak will really screw up the computer, the sensors won't give the computer the information it is looking for, so the computer does the only thing it can, go to limp mode so you can get to the repair shop. Also, those computers monitor the systems based on the different voltage readings from each sensor, corrosion at a wire joint can really mess up the voltage reading to the computer, and when the computer doesn't see the numbers its designed to see, it goes into limp mode.

Without the codes your truck has, and not knowing what has or hasn't been done to your truck, the guys are just going to be guessing. The codes don't usually tell you what is wrong, they report the malfunction the computer records and points you towards where or what to look for. Gene

If it is a “well known problem” then you might go down to a dealership and ask if you could see the TSB ‘s for your year Dakota.

There are some online TSB listing websites but use caution

The most well known 4.7 Dakota problem is the way valve seats drop out and wreck havoc

You mean like there is only one problem that it could be? There are over a hundred fault codes for a reason. If you really want help then provide some info.

THIS! Cant say how many posts i see on the forums where people have issues and don't even provide vehicle, year motor etc...

I bought my 2006 Dakota last winter with 70,000 miles. I purchased from the original dealership from where it was originally purchased from.
I inherited this intermittent, engine light limp mode problem. The truck ran great until the weather warmed up. THEN IT STARTED.

I read all of the different message boards stating this same problem. I am a pretty good mechanic, but electrical and sensor issues are a PIA. For me, the truck deserved the repair, low mileage and a great price. An R/T with a lot of pep.

I brought the truck to the best and most honest mechanic I have ever dealt with. He has a no nonsense approach to all problems.
After leaving the truck with him for a month, he made the repair.

My invoice stated he had 15 hours into the job.
He replaced the transmission sensor (Standard Parts, part# TCS78 STD V) and the computer.

He stated the sensor had gone bad and the computer kept trying to fix the problem. In this year vehicle the engine and transmission share the same computer. The sensor was sensing the transmission was overheating.

No more problem. I am purchasing a heat sink transmission cooler for good measure. I will install this weekend.

Thanks Moparts message board.
