CARB replacement truck already throw codes.

You mean likes those Detroit’s ? Lol

 

Update;

I cleared the 2 codes with the OTR tool I purchased for backup, went to preload locally and the a single code came back on(spn 3226 fmi 20). So I cleared it again with the OTR,( I didn’t do a regen). So this morning I went to deliver my load (ran 200 miles) and no code has showed up. I read some where, can’t recall where exactly, that sometimes the system has to recycle about 3 times(whatever that means) before it completely clears a code, I mentioned on the beginning when I started this thread, that I had the truck threw a code when I purchased it and drove it home. Well that issue was fixed, so I sort of banking on it was the third time this code had surfaced and the recycling period just passed today. Will see..... I’ll keep posting if anything changes.......

 

I’m pretty sure I have everything mixed up “lol” unfortunately...... I run all local, mostly just the Southern part of “Commiefornia”. I’m sure some code will eventually show up.

 

We checked the plungers when they had the fuel pump assembly off to replace the leaky oil gasket. It had the metal ones in it.

 

Update;

I had the inlet Nox sensor(by turbo) replaced. The next day the Def light came on. I did a force regen to a no avail. I took it back to the company shop before it would’ve derate. They had found the plug(hardness) was the issue. Had some debris and it wouldn’t lock correctly. Different tech caught it. So he cleaned it all and connections. Cleared the light and all codes.
