Just had a smog check done on my car.
It failed. They gave me these two code numbers.

PO155 O2 Sensor Heater Fault ( Bank 2 Sensor 1 )
PO161 O2 Sensor Heater Fault ( Bank 2 Sensor 2 )

I checked my Chilton Manual for 1997 T-Bird 3.8L V 6
It doesn't tell me the actual locations for these sensors.
Just very vague locations.

What I need is a picture or someone to give me a more complete answer

Hello and thanks for donating

Both of the oxygen sensors on your vehicle are in the exhaust manifold. The number 1 O2 sensor is at the lower right rear of the engine in the exhaust manifold while number 2 is at the lower LEFT rear of engine in the exhaust manifold. A diagram is below to clarify..
