How Many O2 Sensors Does a Ford F150 Have

Last Updated on by David Jon

A Ford F150 has four oxygen (O2) sensors. Two are located upstream of the catalytic converters and two are located downstream. 

The upstream sensors monitor the amount of oxygen in the exhaust before it enters the catalytic converters, and the downstream sensors monitor the amount of oxygen in the exhaust after it exits the catalytic converters.

The upstream sensors are used to adjust the air-fuel mixture, while the downstream sensors are used to monitor the efficiency of the catalytic converters. If any of the O2 sensors fail, it can cause the engine to run poorly and increase emissions.

In this guide, we’ll delve into:
