Oxygen Sensor

Hey My light went on the other day and had it checked out and these are the codes I got. po141, p0036, and p0054. So I obviously got the idea that its the oxygen sensor. any way to tell which one it is by those numbers?

P0036 HO2S Heater Control Circuit (Bank 1 Sensor 2)
P0054 HO2S Heater Resistance (Bank 1, Sensor 2)
P0141 Oxygen Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)

Looks to me like a bad 02. No other codes than that tho? No P0420 or anything like that?

Yup heater element of downstream HO˛ has burnt-out. You need a new one.

You don't need an other code. Even if heater element is burnt doesn't mean the HO2 is not working .If it gets warm enough by the time it hits closed loop it will not set any other codes. Only codes for problem at hand (burnt heater).
