Engine speed (RPM) sensor, checking: Notes

WARNING: This page is about a different car, the 1999 Volkswagen Jetta, 1998 Volkswagen Jetta, and 1997 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.

The RPM sensor provides an engine speed signal. If the sensor fails, the engine continues to run using a back-up program. The signal from needle lift sensor -G80- is used as a substitute.
