Bank one is on the side cylinder one is on. which is the rear/firewall side of motor. the cylinder head that is furthest forward on the motor is the side cylinder one is on.

The first thing i would check is all 4 abs sensors at the wheels.You can do this with a volt meter set on ac voltage and spin the wheel if it generates voltage at all on the meter its good.

Should be in the manifold on the back side closest to the firewall.

"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.

it will be the sensor on the passenger side exhaust before the catylitic converter

The bank has to do with which side of the engine. The 'Sensor 1' indicates that it is upstream of the catalytic converter.
