Hello, Today I went to get my car's emissions test and it failed. My car is a 1996 Seville STS. They told me it failed because of a bad O2 Sensor. The diagnostic trouble code is P0133: O2 Sensor Circuit slow response bank 1 sensor 1. I plan on replacing this myself but have no idea which O2 sensor this bank 1 sensor 1 is located. Can someone please help me out, If the car doesn't pass emissions then it cant get registered. Thank you for your time

Bank One is the right bank (firewall side). Sensor One is the first one in line. It is on the exhaust manifold (and the hardest one to get at). Sensor 2 would be the Pre Cat senso and sensor 3 is the Aft Cat sensor.

That one is located in the exhaust manifold. It is on the top of the manifold. To get to it, I would remove the ignition coils and the blower motor. It is actually directly below the blower motor. They can be removed with a deep well socket or O2 tool. I find it easier to install them with a crows foot tool.
