The sensor diagnostic software of modular design was developed with MATLAB/Simulink platform based on the main chip of Freescale MC9S12XEP100 by selecting the temperature sensor among the typical analog variable sensors as the re-search object .Through the specific diagnostic algorithm and fault tolerant strategy ,the sensor faults could be detected .The feasibility of the software was verified by the simulated fault on 168F small gasoline engine .The test results show that the soft-ware is stable and ,reliable and the diagnostic effect is obvious .The development project provides the reference for the develop-ment of general analog sensor diagnostic software .
