Just some infofor anyone out there with a 2500/3500 w/5.9L diesel built on or before October 23, 2006. I have been pulling my hair out (what is left), trying to trace a P0191 fault code for two weeks. I had a mechanic here at work that got on their "Snap-on ShopKey" site and found that there is a TSB for this year of Dodge Ram(s) for a faulty computer making error codes show up, specifically the 0191. It only requires a PCM Flash of existing computer. I had tried the "key dance" and mine did not respond, just set there like always. I imagine that this is another fault symptom of the computer too. I took it down to the local AutoZone for a free diagnostic check and they gave me the read out which stated a low voltage to the sensor (P0191). Checked it w/meter and it is fine going in and out of the sensor. Anyway, just wanted to share this with some others I have been chatting with about same problem. I just called a local dealer that scheduled it in and I get mine reflashed next Tuesday to eliminate that pesky light staying on. The dealer's are aware of this but of course don't tell us consumers.............................. JT2500[&:]
