How do you clear engine fault codes?

you should be able to reset the computer by removing the ground cable which is the black one. count to 30 and reattach the cable and that should fix the problem.

The engine management light is still on because there is still a fault on your car.
Get the codes read to find what fault is recorded. It would be interesting to see what current codes are stored and compare them to the codes read out before you got the car "fixed", assuming the codes were actually checked at all.
Once the car is fixed properly the light will go out.

The garage should of cleared the light after replacing the sensor, you need a code reader to reset the light
