  1. CEL P203e w/ GDE Tune

    RAM 1500 Diesel Mechanical
    Today, my '14 ED with 85,000 miles threw the P203e "reductant level sensor circuit intermittent/erratic" code. I've done some reading and understand it's most likely related to a sensor in the DEF tank. I have an extended warranty, so I'm wondering if this is something I should look into having...
  2. DEF Consumption

    RAM 1500 Diesel General Discussion
    I bought my 2016 EcoDiesel almost 2 years ago. For the 1st 16,000 miles I would burn 2 1/2 gallons of DEF every 4,000 miles. When the gauge hit 3/4, I added another jug. Then at a little over 18,000 miles and again 20,500 I am at the 3/4 mark. That is almost double the what it was. My...
  3. GDE Hot Tune Installed!!! Bah-Bye DEF!!!

    RAM 1500 Diesel General Discussion
    UPS dropped off GDE Tuned ECU today and jumped on it as soon as I got home. Only problem with the install is...I have GIGANTIC hands... I have real trouble finding gloves that will fit over my knuckle-dragging hands, and getting those two bottom bolts out and back in was a royal PIA... Once...
  4. DEF System Question

    RAM 1500 Diesel General Discussion
    My DEF Gauge is still reading 1/2-full even after filling with 4-gal of DEF from a Pump at Flyin' J. My 2014 EcoD threw a P203E code, which I cleared with a scanner. I can't tell if the system is using DEF or not, but the CEL hasn't returned. Do I risk any damage to the motor waiting to see...
  5. DEF Service Engine Light - Won't restart in 200 Miles

    RAM 1500 Diesel General Discussion
    So my wife calls me on her road trip with our 2016 Ram EcoDiesel in no mans land, on a Sunday, between Boise, ID and Salt Lake City (less than 18000mi) saying the engine light popped up. It says DEF Service required. Engine will not restart in 200 miles. It has been ticking down ever since...
  6. DEF reading 100% full, when only ~1/4 full?

    RAM 1500 Diesel General Discussion
    I've seen lots of posts on here where DEF gauges are reading too low...consensus seems to be it froze and didn't read a fill, or never dropped level and usually related to very cold weather. I can understand the logic there. My DEF tank is about 1/4 full, and I always keep it between 1/4 and...
  7. 25 days later and.....

    Canadian General Discussion
    it started like a charm... So just came back from my European trip and was a bit concerned that truck may not start after sitting in the cold for a while. Was thinking that diesel may gel-up, DEF freeze and battery dead. But it started without any problems. No hesitation at all. And I even...
  8. Mixing different brands/manufacturers of DEF

    RAM 1500 Diesel Maintenance
    I commonly see DEF from Valvoline and Peak at my local Napa Auto Parts store. Since purchasing the truck, I've only used Valvoline DEF, nothing else. Whom here can share their opinion on my scenario?: My DEF tank is approximately 1/2 full with Valvoline Premium Blue DEF. My local NAPA has...
  9. DEF Gauge faulty?

    RAM 1500 Diesel Mechanical
    The DEF gauge in my 2015 with 5500 Km / 3400 miles was working fine, gauge was indicating at about 60%. Then today it jumped back up to 100% and stayed there all day. Normal day with some light towing and few stops and starts. Outside temperature was about -5 C / 23 F. Everything else looked...

  11. DEF countdown

    RAM 1500 Diesel Maintenance
    Thought this was a nice article on Edmunds about what happens when you run the DEF down to minimal: DEF Jam V: Running It To Empty - 2014 Ram 1500 EcoDiesel Long-Term Road Test Nice to see nothing too frightening. My perception is that the non Diesel owners seem to freak out about DEF. The...
  12. DEF or D.E.F.?

    RAM 1500 Diesel General Discussion
    Six months ago I'd never heard of it, now I've seen it written hundreds of times. But I've never said it out loud (like Voldemort). So, how do you say it? DEF (a one syllable word that rhymes with ref) Or Dee Eee Eff (three pronounced letters)?
  13. DEF, the Weakest link in out trucks.

    RAM 1500 Diesel Maintenance
    (-35c) My wife was on her way to work yesterday when the MIL came on. Stopped by the dealership, they quickly scanned it. Truck said "replace PCM". Service manager said that it didn't make sense, because I have already replaced my PCM @ approx 15k km, and they seldom have to replace pcm's...
  14. ED "Service DEF, See Dealer Message"

    RAM 1500 Diesel Mechanical
    So i have had this happen twice to me. dealer is saying that it is caused by not letting the truck warm up before driving in any weather below -11. dunno if anyone else has had this problem but this is a potential fix… will let you all know if this works.
