they can handle the heat pretty well.
Hey 79coyotefrg,
The zirconium style O2 sensors have an operating range of about 400d F to about 1200d F. Exhaust gases are typically about 600d F at exhaust manifold when engine is at normal operating temperature.
I just don't know how much hotter the exhaust gases would be at the peak of on over-heated engine that heats up and stalls, and at what temperature the O2 sensor actually fails or is destroyed.
Gnarls.
