Hallo Peter, im US-Forum habe ich das gefunden, sollte auf deine 96er zutreffend sein:
On a C4, only a '96 has what I am calling a "Crankshaft Position Sensor."
As far as I know, the manual calls it a "Crankshaft Position Sensor."
It's only purpose on a '96 is for cylinder missfire detection.
No C4 before a '96 has this sensor.
It is located on the bottom of the timing cover and the only timing cover that has the place for it is on a '96 timing cover.
It has nothing to do with the Opti-Spark.
Since the originator of this thread specifically stated a '96, I am assuming it is this '96 only sensor.
The Opti-Spark has low and high-res pulses.
These pulses are detected by the ECM/PCM for what some call cam and crankshaft postion to control spark and injection timing.
All LT1 and LT4 engines have these pulses generated in the Opti-Spark.
On a stock engine, if the low-res from the Opti-Spark is completely missing, the engine will not run.
On a stock engine, if the low-res pulse is OK and the high-res pulse is missing, the engine will run at reduced performance.
I'm told that an engine with the Delteq requres both low and high res pulse to run at all -- and logic tells me the LTCC is probably the same.

Bedeutet also, dass nur die 96er einen Kurbelwellensensor hat. Wenn es ein sporadischer (gelegentlicher) Fehler ist, würde ich erst mal die Kabel und Stecker prüfen, da es bei sporadischen Fehlern die häufigste Ursache ist.
LG...
