heated oxygen sensor fuse FOR rear catalytic passanger side o2 sensor

[BRA0063]

hi, guys I keep getting this warning p0056 and p0161 with a check engine light

anyone know the fix? I know it is the passenger side rear 02 sensor after the cat will replacing this fix these 2 codes or is one indicating a dodgy connection.

is there a fuse I can also check in the fuse box?

is there also a way to test that the sensor connector that connects to the o2 sensor is working properly too?

Normally just replace the sensor. Be careful as there are quite a few different types / plugs used in VE. Also be careful which side the fault code is actually referring to. If you need to drop your cat (front O2's) you will need a couple of exhaust gaskets as well.

So sensor Replace will fix? Is there a way to test the connector
