Is the three-key-flips feature only on earlier versions of the Dakota? I tried that with my 2003 and it didn't appear to work.
According to a co-worker, if you leave the gas cap loose on a newer Dakota you will get a malfunction lamp illumination (MIL lamp). My daughter's old Explorer would get a malfunction indication if she fueled the vehicle without shutting off the engine.
I can't find a list of diagnostic trouble codes in the 2003 Dakota service manual like I've seen in past Chrysler/Dodge books.
#2307 of 4362 P0455 - EVAP Leak Monitor Large Leak Detected
Jul 29, 2003 (4:02 pm)
This is a very common question. I have answered it too many times to count. Here is the "short version":
All modern vehicles (by federal law... aka OBDII) have to test for leaks in the venting system of the fuel tank. The EEC system (Evaperative Emmission Control) is supposed to store up any fumes from the gasoline while parked then feed them to the engine to be burned when the engine is running.
Imagine an underground parkinglot where all of the car fuel tanks are venting gasoline fumes into the air..... the explosion would level a city block!!
The Dakota has several tests that take place based on time, number of starts, temp. and other factors. The test we are concerned with here uses a pump located on the firewall above the engine.
This pump (heard as a ticking or thumping sound under the hood when you start your Dakota) trys to build a slight pressure in the space above the fuel in the gastank.
If pressure cannot be created then thee P0455 code is thrown. This is usually a gas cap that was not tightened according to the owners manual. (On my Dakota, a porkupine had chewed thru the fuel vent hoses and I got the P0455)
One of the other "tests" that are done is the 'pressure holding test' where the pressure in the fuel tank is checked to be able to hold for several minutes.

Does the ignition on-off sequence work to give codes on the newer Dakotas?
Jul 30, 2003 (3:10 am)
Thanks for the suggestions. The gas tank cap was the first thing I tried. I've looked for any loose hoses, but havn't found any. I need to fill up again tonight, and if it doesn't reset by Saturday, then I will disconnect the battery.
The 3 key turns should still work on the newer trucks as far as I know.
1) start with the key turned to the first click (where the steering wheel is unlocked and everything is "OFF")
2) Turn the key to the next position (the "ON" position) and back to the "OFF" position.
3) Repeat step 2
4) Turn the key to the "ON" position and leave it there.
Note: Steps 2-4 need to be a constant pattern. eg - from lock position to the off position, on, off, on, off, on
5) Look at the odometer read out for any P-codes.

When I ordered my 2K Dak CC I ordered the heavy duty battery thinking I would get at least five years out of it. Now I find after 3 1/2 years it is on its last leg. It has never been run down by leaving the lights or other accessories on. I don't have any exotic accessories other than powered MTX Thunderforms, which have been installed for more than a year. Have any others had this experience?

When you got the "heavy duty" battery you got larger amp hour capacity battery than standard. You also got an OEM, low bidder version as well. Cost cutting has its impact in many ways. Rick
#2312 of 4362 Hey Dusty Spark plug question
Jul 30, 2003 (7:44 am)
I did a search on past post, I noticed you placed the bosh 4418 in your truck. Do you still like them I have a 2001 4.7 4x4 with 53k on it and was going to change the plugs, At present I dont have any noted problems just thought I would change the plugs. I did put the Gibson Cat back exhaust on and it sounds better and not much increase in cab noise.
The install was a breeze nice product.
Also does anyone have any experience with those Air type load levelers that are placed to assist springs when loaded? I am placing the IAS edelbrock shocks on as soon as they come in X 4

Ron, batteries like many other electronic components are somewhat unpredictable as far as longevity is concerned. My '95 Dakota had the heavy duty battery, I drove it long distances over highways and it never saw its first birthday. I have had batteries last 8 or 9 years. Many things can happen such as plate sulphating, cell buckling, etc. And this can occur with the charging and regulating components operating properly. I think that Rick's posting presents some practical insight. Let's hope that you fare better with subsequent batteries.

Well, they're okay. I seem to realize a slightly improved idle. Fuel consumption hasn't changed either way. When I first installed them I actually thought there was a slight decrease in performance, however that is a very subjective response. I have no way of measuring any change in performance and whatever "slight" difference I thought I felt, I don't trust my seat-of-the-pants feel.
I only have a little over 3000 miles on them, so longevity is still to be determined. Oddly, I've talked to guys who have gone 30,000 plus miles on the original Champion factory plugs and don't have a complaint. One fellow told me that he went 58,000 on the factory set and his Dakota started and ran fine.
The tips on the factory plugs at 10,000 were showing signs of erosion around the circumference of the top, typical of any ordinary plug. The gap measured a very uniform .042 on all eight plugs, which isn't really bad for a plug with that many miles.
So, bottom line. Did I get what I paid for?
I think it's to soon to tell. But I think it's fair that nothing was hurt by installing them in my 287 motor. But my results may not be typical.
#2315 of 4362 Power stearing fluid leak, please help.
Jul 30, 2003 (5:50 pm)
I was changing engine oil, when I noticed drips of fluid on the shaft and boot. Year and a half ago, I had the upper arm on the same side replaced, under the warranty. I wonder, if they could help this problem. Any ideas, what could go wrong and how to fix it? How do you clean throtle body and what cleaners can be used so the sensors don't get damaged. Thanks!
