Question about 1995 Mercury Grand Marquis
I need to replace the oxygen sensor but have no idea where it's located, Thanks
#3 - Under vehicle, passenger side, below seating area, mounted in exhaust pipe in rear of catalytic converter
#4 - Under vehicle, driver side, below seating area, mounted in exhaust pipe in rear of catalytic converter
In either case, it is mounted on the rear side of the Cat.
Thanks for using FixYa - a FixYa rating is appreciated!!

If I am not mistaken bank one should be your driver side. However your sensor one will be before the cat converter. So you just have to find the o2 sensor before the cat converter on the driver side. Good Luck.
