Anybody know what this means? Threw this code last night and have 2009 6.4L f250

 

do you have an aftermarket intake on it?

 

From the tech folder:
P2002 REGEN Particulate Trap Efficiency
Below Threshold
This error occurs if an expected pressure drop through the DPF
is lower than the specified value following a regeneration cycle
(based on the concept of normalized pressure differential

but like I said, aftermarket intakes seem to throw the code. So if you have an aftermarket one on there...take it off and see.

 

Interesting. Sounds like a "Cracked DPF" code.

Senix, are you sure about aftermarket intakes causing this code? Not sure how one would have anything to do with the other here. Any idea how?

 

aftermarket intake is the cause. Ive stated this more then once.
the maf is the part of the dpf load calc. they take that and dpfe and that is what causes the code.
so incorrect air flow, dirty maf sensor dirt air filter will cause this.
also it is possible to enter excessive regen based on the same wich will reduce fuel economy and incress speed of oil growth.

 

yuppp, cheezit is the master.
