Engine control computer

A computer for a motor vehicle, said computer being able to be electrically connected to a sensor of the vehicle over a wired communication link in order to receive an output signal generated by said sensor, said sensor being electrically powered by a power supply module via a wired power supply link, the computer is configured for:

• being electrically connected to a measurement device by a wired measurement exchange link, said measurement device being configured for measuring the variations in the electric current flowing through the wired power supply link;
• detecting an anomaly on the wired communication link relating to a short-circuit between the wired power supply link and the wired communication link;
• receiving, from the measurement device, measurements of the variations in the current flowing between the power supply module and the sensor when an anomaly is detected;
• and
• estimating the output signal from the current variation measurements received over the wired measurement exchange link.
