I have a 2000 Ford Contour. The engine light is staying on. I did a code search and displayed code PO420 catalyst efficiency censers. Where are these censers located?
Thank You

Not sure why you're expecting to change a sensor here but that code is for catalyst efficiency and that almost always means a bad Catalytic Converter on bank 1
