it can? i supose it is kinda covered up when the lid is on ecu-but will investigate-thank you

will also check the signal wire[white i presume] from the 3 wire lambda sensor
the lambda was certainly active as the lum. afr meter was working/recieving a signal from this wire[whether it was between the voltage mentioned or not i would have to check
