Abstract
A system and method for detection of speed sensor position in an engine comprising speed sensors and a controller having channels each operatively connected to a different one of the speed sensors. A memory stores predetermined sensor position arrangements each identifying, for each one of the channels, a speed sensor connected to the channel, and predetermined engine parameter values each associated with a corresponding predetermined sensor position arrangement. A current engine parameter value is computed on the basis of received input data. The predetermined sensor position arrangements and the predetermined engine parameter values are retrieved from the memory and a predetermined engine parameter value that matches the current engine parameter value is determined. The predetermined sensor position arrangement associated with the predetermined engine parameter value is then identified and, for each one of the channels, the speed sensor currently connected to the channel is determined.
