Where is 02 sensors located and how many on 2014 ford focus?

Answer 1

On a 2014 Ford Focus, there are typically two oxygen (O2) sensors: one located before the catalytic converter (upstream sensor) and another located after it (downstream sensor). The upstream O2 sensor is positioned in the exhaust manifold or the front pipe, while the downstream sensor is found in the exhaust system after the catalytic converter. These sensors play a crucial role in monitoring exhaust emissions and optimizing engine performance.
