A troubleshooting engine light code indicates that the nox sensors are shorted. Where are these nox sensors located, how many sensors are required and what is the procedure for replacing these nox sensors? Thanks

You got 2 of them that's under the intake manifold-the intake manifold here is how the job is done in the diagrams below it will show the location of the sensor as well. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.
