I have a 2000 dodge durango, with the 5.9lt, it has been running just fine with no problems what so ever. The other day the check engine light came on and the codes that it threw were p0121, p0201,p0202, p0203, p0204, p0205, p0206, p0207,and p0208. The first code I understand just fine, but it baffles me on how all 8 injectors could have gone bad all at the same time. The truck still runs, has all the power it used to, although I notice that my idle fluctuates. This only happens occaisionally though. I can drive with no problems for a while then all of a sudden the rpm's become erratic. The times that the truck runs fine the engine light is still on, so I am way confused. i have read on other forums that this could be a problem with the wiring, but have also read that it could be a combination of the map and o2 sensor also. Does anyone have any suggestions? and what could cause this?

 

My first guess would be the PCM(Power Control Module) It sends the information that fires the injectors. If it were me, I would take it to a dealer and have them evaluate the DTC's. You could chase various causes and spend a lot of time and money trying to run them down. You may even want to get a second opinion after visiting the dealer.

Try discontecting the battery for about 5 mins. Reconnect and see if the problems goes away. That will reset the PCM.

 

check the wiring for the injectors... something in common like where the harness gathers up the injector wires, any recient work? issues like overheat, spill oil, wash engine?

Also vehicle is STOCK?

 

Checked into this for you and There is a reflash in a TSB I am trying to link for you...

TSB 18-017-02

sorry "I" cannot post the TSB... the dealer wil lhave it OR try googling it

 

Copy and paste?

 

Thank you I found the tsb but now the problem is finding out all that is written in it. I also found a list of these tsb's here https://techauthority.gltghosting.co...atalogId=10051, i am still trying to figure out what the last column labled recall is supposed to mean. If you figure it out please let me know. I am going to call my local dealer and see if they can do anything about it now that I have a TSB.

 

I guess i do have another question, with there being a tsb on this problem, I am wondering if I have to pay to have it re-flashed, or if this is just something they do since there was a problem with it.

 

You have to still pay for it but I would say they would install the death flash. I can't get this TSB you are talking about and have never heared of it. Please copy and paste.

Also, ^ that link isn't working.^

 

trying again...I guess 3 is a charm

recalls are free -TSB's are you pay

 

That only applies to 5.2L engines as per discription and his is a 5.9L
