There may or may not be any noticeable symptoms when your Ford F150’s oxygen sensor(s) go bad. Without a check engine light, it can be tough to lock down exactly what would cause the vehicle to fail, but oxygen sensors are one of the more common causes.į150 Bad O2 Sensor Symptoms & Causes: Conclusion You’ll go to get an emissions check done, and your F150 fails the test. Often enough, there won’t be any noticeable signs of a bad oxygen sensor. While a rough running engine can be a sign of a bad oxygen sensor, it is often a sign of a misfire as well. This is especially true if the mixture ends up too lean. Without the proper air/fuel mixture, your engine won’t run as smoothly as it should. Either way, like with rotten food, “the nose knows”. The smell is often described as “rotten eggs” or sulfuric. One of the most common symptoms that an oxygen sensor has gone bad is exhaust that does not smell good. This fuel can hurt the catalytic converter. There could also potentially be raw fuel that enters the exhaust. Without being able to optimize the air fuel ratio, combustion isn’t as efficient, and fuel mileage suffers. A bad oxygen sensor can affect the mixture greatly. The engine management computer uses the data from all of the O2 sensors to keep the air/fuel mixture optimized. Your F150’s oxygen sensors are responsible for helping to keep your engine running at optimal efficiency. As a rule, the upstream sensor is more important for engine timing and air/fuel ratios.īy using a OBDII scanner you can determine exactly which sensor is bad, and what is wrong with it. Oxygen sensors after the catalytic converter are “downstream sensors”. An Oxygen sensor that is between the catalytic converter and the engine is known as an “upstream” 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.This means that you need to look up the firing order for your particular model year and engine. Bank 1- Side of the engine with the first cylinder in the firing order.For instance, an oxygen sensor at bank 1 – sensor 1 would be: These codes correspond with what side of the engine they are on (known as the “bank” for cylinder bank) and how far down stream they are.

There are many oxygen sensor related codes.

More often than not, when an oxygen sensor in your F150 goes bad, it will throw a diagnostic trouble code. Here are the most common symptoms of a bad oxygen sensor in your F150: It is very rare for there to be a problem with an oxygen sensor, and not have the check engine light come on. 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). 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. Most of the time, the check engine light will come on. Oxygen sensors can change the way that your F150’s engine runs. The good news is, if you end up discovering that the oxygen sensor is bad, they really aren’t that expensive to replace. Often enough, the only sign of the problem at all is the service engine soon light being on. Your F150 can exhibit symptoms when the Oxygen sensor has gone bad. When an O2 (oxygen) sensor go bad, it’ll cause your Ford F150‘s engine to run less efficiently. Oxygen sensors play a vital role in both engine management and emissions control.
