Hello everyone
I have a TS V6 magna wagon which is in as new condition.
It has only done 118,000klm original.
I have been reading a few threads about oxygen sensors.
Can anyone with some technical expertise tell me how long they are supposed to last.
How often do they need to be replaced? :)

No idea how long they are meant to last but keep this in mind.

Firstly, they are easy to test.

Secondly, if they totally fail your ECU will tell you (via check engine light and diagnostic code).
