Engine Power Reduced

mike2535 · September 15, 2014

Driving down the interstate in my 2008 Chevy Silverado Diesel with 66,000 miles. "Engine Power Reduced and Check Engine light comes on and I cannot get above 30 mph. I was pulling a camper at the time but I have pulled this camper many times with this truck. After I got back home, took the truck to dealership and they hooked it up to computer and it said code #2463 - soot accumulation and diesel particulate filter restriction.

(fuel filter recently replaced). I have read some post that say sensor in throttle body needs replaced. Has anyone had this kind of problem?

So they scanned it , did they diagnose it ? It sounds like you would rather get the internet to do it for cheap ,,,,, sad

At that age of truck I would be ripping the DPF off, for the price a dealer would charge you could buy a DPF delete kit and be done with it

Try cleaning MAF sensor

You're getting that because the DPF isn't going into regen, do you idle the truck a lot? Do you take short little trips around town where it doesn't fully warm up or work itself?

Sounds like it needs a good trip pullin 15k for a few hours and work it hard. The new diesels need to be driven hard to stay clean, they need to get warmed up nice to burn everything off.

Get rid of that DPF
