dealer just changed my nox sensor under warranty. no more issues

In response to WileECoyote, yeah, I'm in the same boat which is that I am also not driving a lot of highway miles. This could result in a lot of incomplete regens, clogged DPF injectors, etc.

If it never completes, it will give the message to "cleaning exhaust filter keep driving til message is cleared" message.

My truck also sees mostly short trips, and I've never had that message. I have had the regen continue for more than one day.

Thats interesting. No I've never seen that message but it sure seems odd to me that I get such shitty gas mileage. I'm going to take it for a good long drive and see what happens. I think these trucks like to stretch their legs anyway.

Same here - I've never seen that message and I've put 3000 miles on the truck since I purchased it - all mostly short trips with only one 300 mile trip.

Sierra, where you at in SE Florida? I'm originally from Ft Lauderdale. Moved away when I was 18 to join the Army and only been back for vaca or funerals. Yeah, Id love to move back but dont really have any job prospects.

Sorry, missed this post the other day... the Nox sensor was replaced and I had the light come on right after I picked it up and turned out onto the highway. I'm pretty sure they heard the tires screaming when I turned it around and headed back at them.

I'm not too sure what to think about this one. When I drive it to work, I do drive short distances, but at the same time, I'd made a couple of longer trips and then hauled a tractor on a gooseneck the day before the light came on this last time.

I see you're running a tuner. Did you get rid of all the emissions crap on yours? I hate to give up the warranty, but if I have to do this again, I'm seriously going to have to consider it.

ETA: Nevermind, I see you've put an exhaust on too, so I guess that answers my question. Are you happy with it?

I've never seen that message myself. I have had it resume a regen the next time I drive it though.


Just got a call from the dealer. They tell me that they think the reason the light came on when I picked it up Friday was that they didn't recalibrate the computer after they changed the Nox sensor. Not too sure whether to call this BS or not, but at this point, I think it is pretty obvious which way I'm leaning on that debate.

I guess we'll pick it up this evening and see how long the orange lights stay off.

I am super pleased with it.

No problem at all, jphippsjr! I’m glad you were happy with Granger Chevrolet. From what you’ve written, it looks like they had great communications with you about this.

I completely understand the frustrations with the truck going into regen so much and I would be happy to provide any updates that are brought my way.

I hope you had a wonderful weekend.
