  • Not sure with that many codes. What is going on with acutal running of the truck? are there any mechanical issues you can notice? If not then I might think about disconnecting negative cable to battery and the reconnect 15 minutes later. It might reset itself which happen with my truck when I replaced the TPS. Did you try this when you replaced the carak and camshaft sensor? I know that when I did this is reset the computer and no longer got the code this was after fixing the problem. let me know if this works Header1974

    Just wonder why I have not seen it in any of the manuals. The FACTORY shop manual clearly explains this (and many other) troubleshooting capabilities of your Dakota.

    *)The FACTORY shop manual has step-by-step instructions how to troubleshoot/isolate most problems.
    *)The FACTORY shop manual lists, diagrams and locates EVERY electricial connector in your Dakota.
    *)The FACTORY shop manual has paragraphs describing EVERY component and its function. (Automatic-xmission chapter is 100s of pages)

    I suspect you are not looking in a FACTORY shop manual. All the other ones (Chilton, Hanes...etc) have no connection to the factory and are very careful to NOT infringe on copywright of the FACTORY shop manual.... thus they necessarrly do not have the same content.
  • I have a 1995 dakota 3.9 a/t that shuts down after 5 to 10 minutes. I have to wait 45 minutes to 1 hour before it may or may not start. It may or may not run for 5 to 10 more minutes. Replaced the magnetic pick up in the distributor,and the fuel pump relay. I then took the truck to aamco for a scan and was told it may be a bad wire in the computer or the computer it self. please anyone HELP BEFORE I SET THISTRUCK ON FIRE!!!!
  • :confuse: I have a 1992, dodge dakota ,3.9L, V 6, 2x4, no air conditioning, standard package that is really screwed up and I've got a problem!! The other day I hit some ''wonderful potholes'' and everything went dark. Mind you this happened at 6:30 am so it was dark out. I now have no headlights, no marker lights (front and back), no brake lights, no dash lights, the anti-lock and brake lights are lit up in the dash and the horn don't blow. I DO have flashers and 4-ways. I have checked ALL fuses and all are good. I do hear a clicking noise (something like a house breaker blowing) when I push in my lightswitch. The sound comes from around the area of the rear wheels ???? I'm looking for some indication as to what direction to go now. If anybody can give me some insight to this wierd mess it would be of great appreciation!!!!!
  • I was told I need a power steering switch for my truck to pass smog. Here's the kicker the factory never installed one. So now the dealer says we will install one for 500 bucks! Have any of you dakota owners run into this problem before? How did you pass smog?

    WOOOAAHHH. Something is fishy here.

    It is up to the MANUFACTURER to guarantee emmissions... the owner should NEVER have to pay for this kind of stuff. Read the Federal Emmissions Warantee that comes with every vehicle sold in USA.

    Besides, what does a power-steering switch have to do with emmissions-control? All the switch does is increase idle a tad when there is pressure in the line... thus keeping engine from stalling when you are mauvering in parking lots.

    Personally - I think you are being fed a line of cr@p.

    Are you CERTAIN they are talking about powersteering switch?

    Something smells fishy to me too. What does power steering have to do with emissions???
  • I would suggest testing PCV valve, hoses (make sure not old and clapsing) and the catalaytic converter test if they are saying your not passing emissions. good luck
  • Power steering switch leak fluid through the wiring to the o2 sensor causing incorrect readings. check to see if 02 sensor plug is wet? If it is, change 02 and ps switch Glenn
  • bpeeblesbpeebles Posts: 4,083
    I could understand that argument.... But the appender said their Dak DID NOT HAVE a PS switch??
  • Did you ever get an answer to your problem? I have a 2001 with the same problem: revs up high when cranked, surges as your driving at a steady speed (around 50), and idles higher while sitting at a light with the a/c on. I've had it to my mechanic 3 or 4 times, and he can't figure it out. No check engine light is on. Any help is greatly appreciated.

    I think your truck's problem could be a bad / stuck injector.
    And the length of your sentence is impressive.
  • ok how would one diagnose thru a mechanic or are there alterneratives not alot of funds available :confuse:
  • decided to open my hood this am and when i opened the air filter wow there was a burn hole in the filter from the hose so now ??? is that my sign to know i have a bad injector :sick: :confuse:
  • wow i had that happen on my 94 dakota the peeps here recommended i replace the relays there is one above the rear wheels that gave me all lights missing in rear then i had to replace the front which is located above transmission. hope it helps
  • bpeeblesbpeebles Posts: 4,083
    I am assuming you are refering to the smaller hose (perhaps 3/4 inch diamater) that plugs into top of air-filter-housing.

    That hose is supposed to only SUCK air into top of cylinder-head for the PCV system. The purpose of the PCV valve is to maintain a slight VACUUM in the crankcase so this hose constantly SUCKS air out of the air-filter-housing.

    If there is backpressure into the air-filter-housing thru that hose... suspect your PCV-valve may need to be replaced... or your engine has excessive blowby.
  • ok so take for instance the pcv valve is defective would that cause the gas to mix heavy in my oil or if i have excessive blowby is that cause the heavy mixture ? what causes excessive blowby a bad injector? another thing would excessive gas in the oil cause the oil pump to shut down? i really appreciate this feed back i hate to have her parked especially in this weather.im in the country and its a long driveway from the bus for my kids to walk in the rain and cold thanks again
    i did notice when i removed the air filter it was actually stuck to the lid as well as having a large burn area at the position of the hose.

    Blowby [sic] usually is from a bad piston ring, which allows the air/fuel mixture in the cylinder to leak past (or blow by) the piston rings, thus contaminating the oil.

    A bad injector, which puts too much fuel into the cylinder, could cause blowby by rinsing the oil film off the walls of the cylinder. The piston rings need a thin film of oil for them to seal properly. Or, you could just have a bad/broken ring.

    I think a cylinder leak down test would be able to tell you if this is your problem or not.
  • thank you for the reply im assuming i have to have a shop do the cylinder leak down test .thanks
