Hi all ☺️

I'm newbie to all of this so excuse me for all of mistakes I might say and if I don't completely understand what you might say to me.hehe.

My story is that I went to an ecu repair shop to delete my dpf from my toyota yaris 2011 model. The guy removed it successfully, then I went down to my mechanic remove the physical dpf. After that I got a P2455 error and the check engine is on and can not be turned off by techstream as wheniturnI  off and on the engine it just turns on again. The ecu repair guy told me to replace the sensor and everything will go back to normal.

Does anyone has any good suggestion for me?

Thank you in advance

In denso after dpf removing in ecu all sensors must be connected it's like emulator.. Check if all sensors connected on dpf.

Hi, thanks for the quick response. Yes all sensors are connected again after the removal

Nope. The problem in still there even with all sensors on. How can I check if the sensors are actually live or broken? So if I really have a broken one then I need to replace it. Correct?
