ABSTRACT:
A diagnostic system for detecting when one or more temperature sensors as found in motor vehicle climate control systems are invalid. The system works at extreme temperature conditions and functions to distinguish between sensor faults such as open or short circuits and true sensor temperature readings, which could be, misinterpreted as faulty readings. In particular, combinations of ambient temperature sensors, in-car-temperature sensors and evaporator air temperature sensors are tested by the diagnostic algorithm to make such determinations.
