Where are the h20s sensors located also the fuse on a Infiniti QX56?
There are 4 of these sensors you will need the find the codes first and replace the correct one.
1. Bank 1 Sensor 1 is located on the passenger side before the catalytic converter (on the header aka exhaust manifold)
2. Bank 1 Sensor 2 is located on the dricer side after the header (exhaust manifold) on the catalytic converter
3. Bank 2 Sensor 1 is located on the passenger side before the catalytic converter on the header aka exhaust manifold
4. Bank 2 Sensor 2 is located on the dricer side after the header (exhaust manifold) on the catalytic converter
it probably wont be a fuse but you can always check it, it is on the passenger side near the engine bay.
