Hi, all,

My knock sensor is bad, I will go to a Toyota Dealer to change it early next week. I am curious if it is easy to change the oxygen sensors during this task?

I have never replaced the oxygen sensors. Considering it is 156000 miles now, my oxygen sensor probably going bad soon. I think if this job can be done during replacing the knock sensor, it is to change them together. I am blind to mechanic, so I don't want to pay double labor for changing those sensors separately.

What is your opinion? Thanks..

 

Totally unrelated and if any you can save some rounding of labor rate and making a separate trip. You can read the DIYs.
