this is just my theory of this (i may well be wrong of course)would it be that the new ecu parameters have been broadened to not flag the code so critically on the lambda reading(not sure if this could not have been done with a remap though)therefore saving toyota hassle of recurring light fault even after new parts have been fitted
waiting for enlightment
