UK Car Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.If bot sensor are not defective then you have to be dealing with a short to ground. I would start with rechecking the power feed wire to the VSS (black/green) for a short to ground. I have enclosed the wiring diagram in the link below for reference.

These circuit and or the components to them have to be shorted to ground or the fuse would hold. What happens if you unplug both new sensors? Do the fuses still blow?
Unfortunately this is all the information I have on this, I will open the post back up for you and perhaps someone else may have something new to add. If they can help, they will respond.
If you've measured the continuity of the wiring from end to end, that would not take into account for a short to earth, all that shows is current can make if from one end of the wire to the other.
A short to earth, that hasn't broken the wire would not increase the end to end resistance.
Try measuring the resistance from the wires to earth, it should be infinite, if not then there is a short somewhere.
