摘要
A method for diagnosing the absence of an under-engine protection of a motor vehicle, includes: estimating a temperature of air external to the vehicle, estimating an under-hood temperature, determining whether the external-air temperature value is below the under-hood temperature value, in the affirmative, calculating an absolute value of a difference between the external-air temperature measurement and the under-hood temperature measurement, determining a diagnostic criterion by calculating a difference between the absolute value and a predetermined absolute value, obtained in the presence of the under-engine protection, comparing the diagnostic criterion against a predetermined diagnostic threshold, and emitting a diagnostic signal dependent on the result of the comparison.
