Something I was wondering about: Does an exhaust gas temp sensor have a service life? I've had mine about a year now, and I was wondering if I should pick up a new probe, or if they're the kind of thing where it either works, or it doesn't. I was just hoping for any input from anyone who's had one for awhile and been able to do any testing of the equipment.

Thanks,
