Hello,
I recently failed the emissions test because of a "bank 1 sensor 2" heater element failure.
I have a Protege LX '98.
Is this what's called a downstream sensor?
In any case, where is it?
Recently I had the sensor at the very front replaced (seemingly just behind the radiator).
I found a cheap replacement online also for the 4-wire downstream sensor but I just need to make sure...
Thanks,
Dimitris
