SIR Label when Replacing Forward Discriminating Sensor
Models:
1994 Chevrolet Beretta, Corsica
The forward discriminating sensor on the above listed models was originally equipped with the attached "NOTICE" label. Replacement parts ordered through GMSPO will NOT be equipped with this label. If the sensor is replaced, the label, P/N 10247726, is to be ordered separately by the dealer and installed on the new sensor.
The 1995 forward discriminating sensor has the same label installed on the close-out panel near the sensor and not on the sensor itself.
If ordering a new sensor for the 1995 "L" car, the label does NOT need to be ordered.
