its the O2 sensor on the driver side above the catalytic bank1 sensor 1 is the passenger side above the catalytic bank2 sensor 2 is O2 below catalytic on driver side bank1 sensor 2 is O2 below catalytic on Passenger side
what side of engin is bank 1
Bank 1 sensor 1 on a '02 Suzuki XL7 should be 5.0 - 6.4 ohms. Looking at the connection with the undo clip pointing down, do an ohms test between the two top prongs. These are the 2 heater wires for the O2 sensor. Depending on manufacturer they will most likely be either 2 white or 2 black wires.

There are 4 Total, 2 per bank. Sensor 1 is the Pre-catalytic converter sensor and sensor 2 is Post cat. (after). Bank 1 is the Driver's side and 2 is the Passenger side of the engine.
where is the oxygen sensor location on a 1998 explorer bank 2 sensor
location bank 1 sensor 1
Bank 1 is the same side as cylinder #1. Sensor 2 is after the catalytic converter.
Bank one is the side of the engine with cylinder #1. Sensor two is after the catalytic converter.
Bank one is the side of the engine with cylinder #1. Sensor two is after the catalytic converter.
Bank 1 (one) is the side in front of car (Bank 2 is rear, firewall side) 02 sensor 1 is upstream, on exhaust manifold (02 sensor 2 is downstream, by cat. conv.)
That is the sensor in the catalytic converter.
That would be the sensor after the catalytic converter.
