How to know when WBO2 needs replaced?
I get about a year of daily driving from the second gen lsu 4.2 sensors if I power them up before I start the truck
Not sure on mileage.
Bosch 17025 I THINK is the sensor that came with it.......
Now what do you mean by powering them up? I know mine goes through it's little startup cycle where if you key on and wait before starting the engine it will show full rich then full lean... Does it matter if you wait for that process or what? I usually just light it up before it does that little procedure.
Are there any telltale signs that it's time to replace the sensor, like how do you know when it's time to order another one?
