Oxygen Sensor Location

[mplieb]

I get an OBDII code of P0133 = O2 Sensor CKT Slow Response (Bank 1 Sensor 1)

Can someone tell me where this is located?

Thanks.

The O2 sensor is located in the exhaust pipes usually before the catalitic converters. They screw into the exhaust pipe and have a wire connected to them running to the engine. I dont know which is Bank 1 in the regular taurus, you would have to ask a dealer. The 3 cylinders in the front are a 'bank' and the three cylinders in the back are a 'bank'. I would think that there would be a sensor for each bank since it is specifing the bank.

Thanks for your quick response. You basically confirmed what I have read, and wanted to be sure - I think bank 1 is associated with cylinder 1.
