On a Hyundai Santa Fe, Bank 2 Sensor 1 is located on the exhaust system, specifically on the bank of cylinders that does not include cylinder number one. For most V6 engines, this would be the side of the engine that houses cylinders 4, 5, and 6. Typically, it is situated upstream of the catalytic converter, near the exhaust manifold. You may need to access it from underneath the vehicle for better visibility and reach.
Bank 1 sensor 1 is upstream bank 1 sensor 2 is downstream
Bank 1 is the bank that sits closest to the front of the vehicle. Bank one is the bank with cylinder # 1. You have 4 oxygen sensors, (bank 1 sensor 1, bank 1 sensor 2, bank 2 sensor 1 and bank 2 sensor2). Follow the exhaust from the head of bank 1. The first sensor you come to is sensor 1, the second is sensor 2.
Try to picture this Bank 1 Sensor 1 Bank 2 Sensor 1 Catalytic Conv. Catalytic Conv. Bank 1 Sensor 2 Bank 2 Sensor 2
3, sensor 1 bank 1, sensor 2 bank 1, sensor 2 bank 2
Bank 1 is the same side as cylinder #1. Sensor 2 is after the catalytic converter.
Is this bank 2 sensor 1 or sensor 2?
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
Bank 1 sensor 1 is screwed into the front of the catalytic converter. Bank 1 sensor 2 is after the cat. There isn't a bank 2 on that year Dodge Ram.Bank 1 sensor 1 is screwed into the front of the catalytic converter. Bank 1 sensor 2 is after the cat. There isn't a bank 2 on that year Dodge Ram.
No, bank 1 sensor 1 can not be used in place of bank 1 sensor 2. There are generally completely different part numbers and need the exact one they are asking for.
Bank 1 sensor 2 is the sensor after the catalytic converterBank 1 sensor 2 is the sensor after the catalytic converter
bank 1 is always the head with the number 1 spark plug and the number 1 sensor is always in front of the converters closest to the motor
Bank 1 is the driver's side, bank 2 is the passenger side. Then you will have sensor 1 and sensor 2. Sensor 1 is before the catalytic converter (closest to the engine), and sensor 2 is after the catalytic converter. So Bank 1, Sensor 2 is: the driver's side , after the catalytic converter.
