P0157 OBD Engine Code Logo   Code #P0157 -
O2 Sensor Circuit Low Voltage (Bank 2 Sensor 2)

Select a Code:

This represents an error related to the Oxygen Sensor for Bank #2 which is after the Catalytic Converter. This generally does NOT mean that the Catalytic Converter is bad, but could mean that your engine is running lean, leaks in your exhaust system, the O2 sensor itself is bad, or (of course) the Powertrain Control Module (PCM) is damaged.

car jerks very hard and sputters along but will not accelerate, gas pedal does nothing, and eventually car loses power

check engine light, P0157 and P0158 code

Vehicle will start, but after a while, vehicule will die in any stop. Kind of like power reduced suddenly.


Getting P017 and P0159 and have loud exhaust. Reset the code and it comes back a few hours to a few days later. Have not attempted any repair yet.
