I see one after the converter which is right berlow the oil filter but there is another on further down after a Y pipe. That one is covered in oil from a leak I hasve and my guess is that is probably the bad one but I want to be sure before I go through the trouble
Thanks

P0136FordO2 Circuit (Bank 1, Sensor 2)
Bank 1 is always the side that No.1 clyinder is on. This case it is the Bank closest to the firewall (Passenger side)
Sensor 2 means the sensor after the catalytic convertor.
The sensor you need to look at would be after the cataylic convertor on the passenger side of exhaust.
