Bank one is the same side as cylinder one, this varies per manufacturer, but is generally on the passengers side of the car, so bank two would be opposite, then sensor 2 would be AFTER the catalytic converter, or post converter O2 sensor. Follow the exhaust to, or just past the catalytic converter and it will be the only thing connected to the exhaust with wires on it.
You do not, you repair the problem.
On a Hyundai Sonata, the O2 sensor bank 2 sensor 1 is typically located on the exhaust system, upstream of the catalytic converter on the side of the engine that corresponds to bank 2. For a V6 engine, bank 2 is usually the side opposite the engine's front. You may need to lift the vehicle for better access, as it's often positioned under the vehicle near the exhaust manifold. Always consult your vehicle's service manual for specific details and diagrams.
The bank 1, sensor 3, O2 sensor would be the O2 sensor post cat.
the o2 sensor is located at the left side of the engine towards radiator and is the upper o2.
In a 2006 Hyundai Sonata with a 3.3L engine, the bank 2 sensor 2 (also known as the downstream O2 sensor) is located on the exhaust system. Specifically, it is positioned after the catalytic converter on the passenger side of the vehicle. To access it, you may need to raise the vehicle for better visibility and reach.
You did not specify which O2 sensor it is. Is it sensor 1 bank 1, sensor 2 bank 2, sensor 2 bank 1, or sensor 1 bank 2. There are four O2 sensors on a mazda 626
usually bank 1 is the bank with # 1 cylinder in it and sensor # 1 is the front o2 sensor(usually in the manifold). You will need a O2 sensor socket or a 22mm wrench or deep socket.
P0137 = O2 sensor circuit low volts (bank 1 sensor 2). Could be a faulty B1 S2 O2 sensor.
Bank 1 is the bank of cylinders that contain the number 1 cylinder. O2 sensor 1 is the first O2 sensor in the exhaust system between the engine and the catalytic converter.
Is this bank 2 sensor 1 or sensor 2?
Where is the o2 sensor on an o4 hyundai sonota 4cyl bank1 sensor2
Bank 1 is the bank of cylinders that contain cylinder 1. The O2 Sensor 1 is the O2 sensor located in the exhaust system between the cylinder head and the catalytic converter, also known as the "upstream" O2 sensor.
