P0137 02 Sensor Circuit Low Voltage - OBD-Codes.com

Check vacuum hoses loss or not connected and O2 sensor wires to see if is pinched making a short signal to the CPU.

in barstool talk:
the rear oxy is toast. get a new one.
if v6 engine, then post that, and we an tell which it is. but is bank1 no matter, bank one means side of engine that has #1 cylinder

- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit fuse
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
- Faulty Engine Control Module (ECM) (NEVER)

this is how it goes, this car all depending on the engine size can have 2 or3 or 4 sensors,

sensors are labeled bank 1 sensor 1 or bank 1 sensor 2 and then bank 2 sensor 1 or bank 2 sensor 2.

sensor 1 on either bank is the front sensor before converter closest to engine.
sensor 2 either bank would be the rear sensors after the converter.
bank means which side of the engine,

bank 1 is the side in which the # 1 cylinder is on,
For example a 4 cylinder engine would have the bank1 sensor 1 on the top of the exhaust before the converter and bank1 sensor 2 would be down on the exhaust after converter. it may not have a bank 2. but newer 4cyl are starting to have bank 2

A v-6 engine would have 4 o2 sensors with same concept except one on each side of engine and then one at rear unless using two converters then one after each converter.

if you do not understand this then tell me year,make model and engine size and the complete code like bank 1 senser1 and i will tell you exactly where it is. good day.

Bank 1 is always the same side as the number one cylinder. Bank 2 is the other side of the engine. Sensor 1 is always before the catalytic converter and Sensor 2 is always after the catalytic converter.

If you have a 3.4 liter V-6 the #1 cylinder is on the passenger side. If you have the 4.7 liter V-8 the #1 cylinder is on the drivers side.
