My thoughts has also been on looking into the mass Air flow sensor so i will do that and check the air filter. If still the problems occurs then my last step will be buying a new a/f sensor - toyodiy homepage gives me part number 89467-52070
I will se if i find denso in first hand before looking at other producers :)
Thank you for your advice :) i will be putting in the outcome when im done. Will take a while before reposting :)

Hi there, I am having the same issue just know, first it happened on april this year, but now in last 3 weeks I had P2196 error.

I have bought new A/F sensor Denso DOX-0269 - but then shortly after the restart I got error message code P0031. We have checked both of the sensors, the resistance was there. Then I returned the new sensor to the shop and for now I am on the old one after clearing P0031 it was ok. But after 100km again P2196.

Any hints or thoughts guys?

Any help appreciated!

Thank you

Joe
