has speed sensor blown

hi guys,

I had a mechanic change my speed sensor but he cut thru the wiring leading from the sensor plug to the loom. He reconnected wiring but got it wrong. I keep getting the same fault code even after resetting (g28-no signal) symptoms with the car are exactly the same as before.

The qustion is... Has he blown the new speed sensor. I know 1 of the three wires is a live wire. An auto-electrician reconnected the wiring properly but didnt check the sensor.

anybody know if this would have destroyed the new speed sensor (hence the same problem)

I have posted 2 previous messages and only got 1 reply. Maybe i have broken etiquette rules and for this i appologise, but help would be appreciated.

thanx in advance

Mike
