Probably provides RPM reference for idle speed management, rev limiter and lets ECU know the car is running for the "auto start" function. I'd like to know more about it myself...

Is the car stalling only at idle? Does it seem to have trouble maintianing a steady idle when it stalls or does it stall at higher RPM's and speeds as well?

The sensor is on the left side of the engine at the back in the rounded part of the block that joins the transmission. The wires pass out of the sensor and around the starter and are incorporated into the starter wiring harness to go wherever that goes. Maybe the sensor wires are getting too close to something related to the starter and they're getting an EMP from the starter or it's wiring which finally kills the sonsor... shrug...
