What happens if I expose a sensor to temperatures outside the quoted operating range?
Generally the effect of low temperatures is less of a problem mechanically as the liquid electrolyte in all the sensors except the Oxygen sensors will not freeze until around -70°C. Prolonged exposure to very low temperatures may cause problems with the plastic housing leading to cracking. The Oxygen sensor electrolyte will freeze around -25 to -30°C although the high salt content means that it will not necessarily cause immediate damage. It is possible however that the sensor will fail as a result. Temperatures above the top limit put stress on the seals on the sensors that will ultimately cause leakage of electrolyte to occur. The plastic bodies used for most of the sensor moulds will soften above 70°C causing sensor failure quite quickly.
