The sensor is on the transmission it is a pulse generating sensor that increases frequency of signal the faster you drive, the sensor has two wires on it a dark blue/black and a yellow /white wire. There are procedures for testing its resistance and its frequency at various speeds. Should be easy to replace if found to be faulty. If faulty cruise control and speedometer have probably stopped working as well.
i cleared the codes and the car worked fine for 10 then began doing it feels like it disengages and reengages with a bang. i am familiar with speed sensors,i build transmissions for semis . i will test it tomorrow the speedo is erratic and drops when it bangs. thank you for your help.
