Engine speed recording: Notes

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

The crankshaft sensor is required for exact engine speed recording. This also enables misfire detection and rough road detection.

The smooth idle speed evaluation only works when the engine is running at idle (cold or warm). Individual cylinders with a bad combustion performance are pinpointed. The rough road detection detects rough road driving on a poor-quality road surface.
