Same bank as cylinder # 1 and rearmost sensor behind converter (downstream)
Bank 2 is on the passenger side on a Chevy V6 or V8.
PO137 (Sensor Circuit low voltage Bank 1 Sensor 2) This is the O2 sensor behind the Catalytic Converter on the #1 spark plug side. Check the wiring on that sensor before proceeding. More than likely replacing that sensor will solve the problem especially if you have over 75,000 miles on the vehicle. But there is no guarantee that will fix it.
Heated Oxygen Sensor (HO2S) Circuit Low Voltage Bank 1, Sencor 2
what year is the dodge ram? 1999 dodge ram 1500 has the bank 1 o2 sensor located right after the catalytic converter
The sensor is left bank 1/1 is ft and 1/2 is the rear NEW ANSWER: Bank 1 is the drivers side of the engine. Sensor 2 will be the second sensor in the exhaust pipe on that side of the engine. Start were the exhaust pipe bolts to the engine and work your way down the pipe until you see the second sensor and that will be the 1 you need.
It's the sensor before the catalytic converter. The 1500 has 1 behind & 1 after the cat
That is the O2 sensor in the pipe after the catalytic converter.
Bank one is the bank on the drivers side. The O2 sensor will be the first one going from the engine screwed into the exhaust system.
Bank 1 Sensor 2 is the sensor AFTER the catalytic converter. Causes could be,A faulty O2 sensor, Exhaust leak near the sensor, Damaged catalytic converter, Damaged wiring to O2 sensor,
On GM, bank one is drivers side of engine, bank 2 is passengers side. Sensor(s) 1 is the upstream sensor, meaning BEFORE catalytic converter. Sensor(s) 2 are located downstream, or AFTER the catalytic converter, therefore, bank 2, sensor 2 is located in the exhaust pipe leading from the passenger side of engine and after the catalytic converter.
Bank 1 driver side sensor 2 rear sensor. Good luck
Sensor 2 is the downstream sensor (after the catalytic converter). Bank 1 is the drivers side of the engine
