Ok. So I've had the truck for just around 3 weeks. Barely over 1000 miles on it.

Last week my CEL came on with code P2000. The next day my OHC said Catalyst at 80%. I drove it about 10 miles down the interstate and all was well.

Until today. My CEL came on with codes P1451 and P0000. OHC says System OK.

I've searched and read on here the mess about driving down the road, no idling, etc. I drive 30 miles in the morning and 30 miles in the afternoon at highway speeds, with about 15 stop and goes during the day (I'm a bread man). The truck does not idle during my stops. Exhaust brake is on 99% of the time.

I am not sure what version I have in my PCM. My truck was built November '07.

Is a flash necessary/will it help? If I take another trip down the interstate will it clear out these codes?

Any and all info will be appreciated. I searched but to not much avail. Thanks in advance!!

 

So since I haven't gotten any replies yet I've been doing some research on here, using different search words. I found out about TSB 18-13-08. However it isn't listed on the Wiki here. I've read different opinions on it and statements about it.

Will this help with the 1451 code?

 

I seen this earlier... I don't know... sorry.

Take it to the dealer. It's under warranty, right?

Sorry I was no help...

 

The P1451 Code Is A Dpf System Performance. What Is Happening Is That The Egr System Is Clogging Up Ur Dpf Filter. U Need To Get It Into A Dealership Soon. What They Should Do Is Replace The Dpf, Cats, Drill And Tap The Turbo. Run Cleaner Threw The Turbo And Pull Apart And Clean The Egr System. I Have Never Hurd Of The P000 Code. There Could Be A Code P2262 Which Is Turbo Boost Mechanical Pressure Not Detected.

 

I have talked to ^^^^ (he is a buddy of mine) and they are doing a ton of these. The newer trucks are already coming drilled and tapped (the turbine section of the turbo) for the cleaning tool to attach. They are finding a ton of trucks completely PACKED with soot/carbon and have to totally disassemble the emissions system to clean and or replace. one good thing to do is at least once a week go out and run the pizzzz out of it to burn off the soot. hook up to a trailer and beat on it for a few miles.

 

Well, I drove it down the interstate again today, running it hard. Stopped and grabbed a bite to eat. When I came out and started it up, the CEL was still on, so I headed to the dealer. Made an appointment for Monday.

Came out, started it up, and the CEL was OFF!! Been fince since. I'm gonna keep the appointment though just to have them check it out. I hope this DPF crap goes away once I get my trailer going next week and start driving 30 miles 60mph one way each day. Surely that will let it go through it's regen when it needs to and not clog up the DPF.
