CHEVY SPEED SENSOR

2002 Chevrolet Impala

Engine Performance problem
2002 Chevy Impala Two Wheel Drive Automatic 150000 miles

Why does my 2002 Chevy Impala keep blowing speed sensors? They work for a week or 2 and thee car starts to jerk and the speedometer needle keeps bouncing from 0 to 50 or 60 and back to 0. The car acts like it is trying to cut off.

Check the crank position sensor.
