Lexus is220d P1426 after remap , egr off , dpf off - Miłosz - 18-06-2017
I have sometimes problem after dpf off , egr off and remap. When i am driving on 1st 2nd gear with full power i don't have any problems when i drive on 3 , 4 ,5 gear when i use full power more than 2.4 rpm i have P1426 - Differential Preasure Sensor (Installation). I unplug my sensor form two rubber tubes and start engine. I felt only from one pipe little "air". What coule be wrong here ? Is it soft problem or maybe should i use compressor and blow those pipes ? Or maybe my sensor is dead ? I cold also insert here live data with Differential preasure sensor , and freeze frame (x431 pro). Thanks for help.

All of that was made by tuner by MagPro X17. Firstly was dpf off and egr off (there was a problem with scv , cuz fuel preasure wasn't good) after replace scv valve was made remap. So it could be a soft problem ? Ash count and what else ?

I have easydiag (yellow head) with X431 PRO offline and i have also techstream with clone mvci. I thought that i will come back to my tuner and he will correct my soft according to your instructions.
