Engine speed signal, checking: Notes
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2006 Volkswagen Golf, 2005 Volkswagen Jetta, 2005 Volkswagen Golf, 2004 Volkswagen Jetta, and 2004 Volkswagen Golf. However, it is still accessible from the selected car via links, so may be relevant.
The engine speed sensor signal cannot be used further in its direct form, therefore it is processed by the engine control unit for further consumers. The signal is required, by amongst other things, the automatic gearbox control unit to calculate gear changes and the rev counter in the dash panel.
