How long do Lambda sensors last?

[SteveMJ]

Just received a Walkinshaw exhaust today. I'll be fitting soon (with help from Rich24 - thanks) to my VXR8.

I've done 60k miles and the last 50k with LPG, do the rear lambda sensors need changing?

Thanks, Steve

Unless there is a problem with them, then no.
