What is the oxygen sensor on a F150?
Your F150’s oxygen sensors are responsible for helping to keep your engine running at optimal efficiency. The engine management computer uses the data from all of the O2 sensors to keep the air/fuel mixture optimized. A bad oxygen sensor can affect the mixture greatly.
What is the first O2 sensor?
Sensor 1- Sensor 1 would be the first O2 sensor in the line of sensors starting with the exhaust manifold and making its way back to the exhaust pipe. An Oxygen sensor that is between the catalytic converter and the engine is known as an “upstream” sensor.
Why does my check engine light come on?
It’s a good thing that the check engine light would come on, as there is more than one oxygen sensor, and they can be difficult to get to and test. The trouble codes associated with the OBDII scan will reveal which sensor is at fault and why it is bad (at least what the computer thinks is wrong).
