I have been getting a PO141 on my 1996 Land Cruiser. It appears through my research that it points to the rear sensor, which as changed about 5 years ago.
Just for kicks I hooked up my Icarsoft reader that I use for my Range Rover. This reader provides OBDII data streams. Interestingly the data streams indicated that both the front and rear O2 sensors were both registering less than .1 volts...both were registering between .02 and .06 volts.
I would think the voltage would be higher, especially for the front one that is not throwing a code. Is this indicative that both sensors are bad?
