Question about 1999 Dodge Durango

Open Question

PCM I also have a 99 Dodge Durango, and my truck has been dying without notice. After it dies, the check engine light comes on, the 'low gas' gauge comes on, and the 'no bus' displays on the odometer reading. I have replaced the crank sensor, and that was not the problem. My truck is currently at the dealer to replace the PCM. Please advise if you think by replacing the PCM will resolve the problem. Thank you.

SOURCE: durango error in odometer window - nobu5

Hi it's Gord from the June 9th posting. Found out problem to be the computer under the hood located on the passenger side above the front wheel well. Unit has 3 connector plug ins feeding it. Computer had to be replaced. Cost of unit $465 in Canada.

Soon as unit was changed out, engine fired immediately upon turning on the ignition. Problem solved. Hope this helps anyone fast track a solution if they are having the same problem.

SOURCE: 1999 dodge durango 5.9 cranks but wont start no

It is your computer. I had this recently as well. No Bus means no connection to the on board computer. There is a company in Florida that repairs these computers, so don't get suckered in by the dealership for 750-1000.

SOURCE: 2002 Jeep Liberty fuel gauge always shows empty

I don't ever remember seeing a fuel gauge that was connected to the pcm in any car. There pretty much isn't any reason it would be. I have seen numerous problems with dash plug connectors that can cause various gauge problems.(most times cured by cleaning and sometimes slightly bending prongs to get better connection) The sending unit in the tank is part of the pump assembly. i would check for good dash connection and power and continuity at the sender. but question why the pcm needs to be changed, and would only change my opinion if someone could show me a schematic that proves that the gauge connects to the pcm..

No bus on instrument panel of a 99 dodge durango

pcm. the way to check it is, when it dies, open hood and shake the 3 connectors on the pcm which is on the drivers side inner fender under the hood. if you do this with the key still on, you should hear a bing and the gauges should come back on. That means power is back and you should be able to start the vehicle again. if that is the case, it is a bad pcm and you can find someone online who you can send it to to get the pcm rebuilt.

When i start my 99 dodge durango check gauge light come on

That means that one of the gauges are low. Or that something is wrong. Maybe the oil pressure is not coming up like it should. Or that the temp sensor is sending the computer a false reading saying that the temp is too hot. You will just have to look at the gauges to see which one is in the red.

Check for a vacuum leak or torn air intake duct that's letting in unmetered air. Also check the accuracy of the engine coolant temp sensor. Finally, find out why it's overheating at idle--that's really serious. Most common cause is a failed radiator fan relay.

My 92 Dodge Dakota keeps dying while in motion

I had same problem with 99 Durango.
It was an easy and cheap fix -- I went to and learned common problem with 98 & 99 Durango -- sounds exactly like your problem. I was encouraged to replace the PCM "Brain" and was advised of an online Refurbished PCM dealer located in Florida. You can google as I forgot the name. I called them and they confirmed an easy fix w only 3 screws to change out the brain. The cost was < $300.00 and my son & bro changed it out. Runs great ever since -- I was so grateful for for delievering this information to me. My car would die on me without warning -- totally unreliable and dealer and mechanics had no clue. Your problem sounds like mine -- call the PCM reburbishing company and see what they think.

99 Dodge Durango Dies When Slowing

Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
