What does error code p0157 on O2 sensor mean?
This means the signal voltage Bank 2 Sensor 2 of the O2 sensor is below normal. Check Engine light is the most obvious symptom for Error Code P0157. It will not usually cause drivability issues, since it only suggests an input that measures the efficiency of the catalyst (unlike the front Oxygen sensors).
Where is the p0157 code on Bank 2?
The P0157 code refers to a potential problem with the #2 sensor on Bank 2 or its circuit. This code applies to the downstream oxygen sensor located right behind the catalytic converter. If your OBD-II scanner registers this code, you can either let your mechanic handle it or address the issue yourself.
What is the p0157 code on a Toyota Camry?
The P0157 code is set when the Engine Control Module (ECM) detects that the rear O2 sensor signal voltage remains excessively low for an extended period of time. The heated oxygen sensor 2 (HO2S), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank.
When to use the PCM error code p0157?
Error Code P0157 is set when the PCM determines that the O2 sensor has been in low voltage longer than specified time. This means the signal voltage Bank 2 Sensor 2 of the O2 sensor is below normal.

What does p0137 mean on an oxygen sensor?
For example, a P0137 on a Toyota translates to “Oxygen Sensor Circuit Low Voltage Bank 1, Sensor 2”; a P0137 on a Chevy, meanwhile, is “Heated Oxygen Sensor (HO2S) Circuit Low Voltage Bank 1, Sensor 2”. Since translations vary, the possible causes may also differ depending on the make and model of your vehicle.
