This code usually appears on vehicles with fuel-injected engines and can cause a lot of stress for car owners. In this post, we will talk about everything related to this error code, including its causes, symptoms, and solutions.
What is the P0141 fault code?
The P0141 fault code indicates that the Bank 1 Sensor 2 O2 sensor is not working correctly. It is usually seen on cars that have a four or six-cylinder engine and are fuel-injected. When the sensor does not provide the correct information to the Engine Control Unit (ECU), it can cause the emission system to perform poorly or even fail. This error code can trigger your car’s MIL (Malfunction Indicator Lamp), which can indicate the severity of the problem.
