Sure I know what it looks like!!! sheeesh, I Googled it!

Joking aside.... for now.

Guess I'll run the voltage tests and determine if I do actually need to replace it; rather than blindly going in a direction (like changing the O2 sensros when I wasn't getting any CEL, just the bad odor).

I always appreciate you letting me learn!

 

A great way to look at things is this at the 120K to 160K mileage mark you should start replacing all your sensors as they are getting old and may start giving out slow or bad info to the computer.

Be sure to save the old sensors as they may come in handy at a later date be sure to label them so you know what they are and where they come from.

I good process is also to get one brand for any group of sensors like the O2's all NTK is a good example.

Each sensor may not be bad yet but it will be soon or is just slow at those mileage points your O2's are a good starting point and the TPS and MAP.

Why waste time testing just replace in steps it will be needing replaced its just a matter of time at the 120K to 160K point things are getting old

 

The TPS was changed about 2 years ago around around 175K. The front 2 O2 sensors last month (NTK). Now that i have 206K, I guess I'll do the MAP sensor.

Truth is, Until the winter gasoline mix ends in the spring, I'll not know what the mileage is; I've made a few other changes/improvements this winter. I really don't care which item(s) improve performance or mileage, as long as it moves in the right direction.

Now, to find the MAP sensor at a reasonable price... seems they've gone up in the past few years.

 

You have the 4.7, right? Rockauto has one for 15.

 

I looked this morning and just now, I see rock auto for $79+ Maybe I'm not looking at the right thing... please post a link.

Thanks!

 

Like I said, maybe I don't have the correct item here from Rockauto.com:

2001 DODGE DAKOTA 4.7L V8 SOHC : Fuel/Air : Manifold Pressure (MAP) Sensor Price

AIRTEX / WELLS Part # 5S2439 {Click Info Link for Alternate/OEM Part Numbers} $79.79

STANDARD MOTOR PRODUCTS Part # AS141 {#56041018} MAP SENSOR $79.79

DELPHI Part # PS10042 Sport $85.79

 

Thats correct Robbadodge

Thats what I see also some years the MAP is $$$$ some not.

At that price I suggest your local auto store but dont get the cheapest one in the store

 

Between my previous post and now, rockauto went up a dollar... TFF

local places want $113 +tax, dealer wants the $98+tax/ I purchased the Standard from RA and paid $86 out the door.

ah well.. get it by the weekend and cross another "new to me" item off the list.

Thanks again!

 

Just to update..

Changed the MAP sensor Sunday and was able to give it a real drive today. Definitely a lot of the same input from me that I've read from the many others in this thread... improved shift timing when on an incline is the best I can say right now. I'll be taking a road trip soon enough and see where the winter mix of gas puts my mpg; it's been averaging 16.5 that past 2 road trips.

Thanks y'all.

 

Very useful thread. My dakota currently gets less than maybe 12mpg.... this would be worth the investment. I think I'll order the standard from RockAuto as well and see if it helps. I've already done fuel injector cleaner and other treatments with not much improvement. Will post changes.
