Re: O2 Sensor Curiosity Question
i changed my front sensors a year and a half ago, approx 9000 miles. I have just changed my bank 2 sensor 2. I have not changed the other one yet, because the weather stinks.
i do not think there is a correlation between the fronts and the rears.
BTW, i have about 135,000 miles on the truck.
I used oem sensors for the front and am using Bosch universal sensors in the rear.
so far so good
