Hey mates,

I have just made a DPF_OFF on a Fiat Doblo 62KW 1.3 MJet with VOLTA SENSORS... (tried with ecusafe too but it's not working!!)

I have tried this dpf_off on many cars including Dolbo Mjets but on this one after the DPF off (with CMD flashtech) i have the check engine on with the fault code P2453.

The fault P2453 (differential pressure sensor?) can be deleted but on the road it pops up after 500m of driving...

Has anyone seen this before? Can the fault code be erasen?

Thanks

Hey mate,

This file is the same with what ECUSAFE software indicates as a dpf_off procedure....
Have tried it and car won't rev up to 3500rpm!

I have done it with VOLTA (Volta never let me down on dpf off)! And dpf off worked! Just the check engine light is on!

And i have asked for advice because i have read this : -> Technical: Sedici particulate filter - The FIAT Forum (http://www.fiatforum.com/sedici/226767-sedici-particulate-filter.html)
Check the 2nd post! It says there is a software that can delete this fault! Has anyone seen this?

Did you try to clear dtc table with a dtc remover?

I have tried cleaning the dtc with MultiEcuScan (which i consider good for Fiat vehicles) but this fault is permanent

I didn't mean a device which can erase fault codes.
I mentioned about softwares which can erase dtc tables.

Ecu safe can do it most of the times; you should just push the dtc table button, but there are a few programs more which can do it.
