Bought a cheap downstream o2 sensor, work for a couple of days, then I got hi voltage code. I see the voltage will get to 1.25 volts. The original sensor had no voltage output. I need to
replace this sensor, but with what brand. The dealer wants 115.00 for one. Looking for recommendations on a good o2 sensor that will work and not cost over 100. There are many o2 sensors out there but like to here from someone who has had successfully replaced one with an after market sensor.
