Engine speed: Notes

WARNING: This page is about a different variant/trim than selected.

The TCM control module receives information about the current engine speed via the bus. It compares the engine speed with the speed of the input shaft when lock-up is activated. Deviations greater than 100 RPM between the engine speed and the speed of the input shaft will cause diagnostic trouble code P0741 to be generated.
