Crankshaft Position (TDC) Sensor

Using an Ohmmeter, check the resistance between terminals 8, 9, and 10 on the engine diagnostic plug. The resistance should be:
Between 8 and 10 80 ± 10 Ohms, at 23 ± 5°C (73 ± 9°F)
Between 8 and 9, or 10 and 9 at least 60K Ohms
Replace the sensor if it is not within specification.*

* The TDC sensor is used for checking ignition timing only. It has no Motronic function.
