The EGR valve is attached to the intake manifold near the throttle body and the 1/1 O2 sensor is on the rear exhaust manifold.

if u have one oxygen sensor then u need to take a deep look at the bottom of ur car it will be somewhere at the Exhaust pipe if u have a catalytic converter then u will have two oxygen sensors one before the catalytic converter & the other will be after the catalytic converter. Note: the catalytic converter is located at after a little bit of beginning in Exhaust pipe.

"Bank one" is the bank of cylinders that starts with the #1 cylinder. In this case this will be the bank of three cylinders that is closest to the firewall. Sensor #1 refers to the O2 sensor that is between the engine and the catalytic converter. So the Bank 1, sensor 1, will be the O2 sensor that is mounted in the rear exhaust manifold or tubing just before the cat.
