hello.

a second oxygen sensor went bad on my ford explorer 2019 at 53k miles.

the first one i brough to dealer and it got replace (allegedly). now they are telling me that another oxygen sensor has gone bad just 4 months after the first issue.

from my internet search, it should be lasting longer than 53k miles.

can it be possible that dealer never replaced the sensor the first time around and just erased code, and it took 4 months for the code to come back up?

how can all these parts go bad just as the warranty runs out?
 






You sure a mice did not eat the wire? Happened on my 2019 Taurus SHO, Bank 2, Sensor 2.
