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
You need to change the upstream sensor
Is this bank 2 sensor 1 or sensor 2?
Bank 1 is the same side as cylinder #1. Sensor 2 is after the catalytic converter.
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 2 is the sensor after the catalytic converterBank 1 sensor 2 is the sensor after the catalytic converter
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.
where is the bank1 o2 sensor at and how do i change it please i need your help
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.
