Hot Truck - Regen?

[TMyers]

I had to make a trip to Tractor Supply this morning. When I got home, I could smell my truck was hot. I had to go around to the passenger side front door and I could feel the heat on my legs coming from under my truck. Did I cut a Regen. short? Will it resume on my next trip?

Yes, my '19 will resume on the next start. I have gotten pretty tuned in to the change in sound of the engine when it'd doing a regen and, if practical, will generally drive out US60 for a few miles until it completes it. Obviously, that's not necessary, it's just OCD. And yes they do get a little hot and stanky during a regen.

Yes sounds like a regen.

My CTS2 will tell me when I’m in regen but I cannot hear, smell, see, or feel a difference from the drivers seat. If it is going on when I put it in P and get out I can smell it and feel the heat of I get close enough.

That's how the regen is suppose to work, if you shutdown truck in the middle of regen, next time you start will continue with the regen, no input from the owner.

 

[AH64ID]

Exactly. Park is what shuts it off. If I’m in regen and have to shut it down I’ll idle a little extra, but that’s my preference and not required.

My Truck is a 2013 with 102K. I have only ever had one Regen that showed on the EVIC. I guess that came about because of too many low RPM short trips so it needed to force a Regen. Any others must have been passive without me ever knowing.

Active regens are happening normally without you knowing. The only time the EVIC shows a regen, pre-19, is when the DPF is close to full. Normal active regens are not noticeable to the driver.

Passive regen is happening on most drives that aren’t city driving which will help the engine keep from doing active regens in addition to the minimum 24 hour run time interval.

Since I started tracking regens I’ve only had the 24 hour regens, which includes some pretty slow and low mpg time. I have seen my dads ‘17 go into stationary regen while hunting thou.

I always laugh when my truck goes into regen after a long day towing, but it’s the 24 hour regen and it really doesn’t do much since the DPF backpressure is nonexistent after a long day towing.

Long story short, divide your engine hours by 24 and that’s the minimum active regens you have had.
