What happens when the oxygen sensor goes bad on a GMC Sierra?

When an O2 (oxygen) sensor go bad, it’ll cause your GMC Sierra ‘s engine to run less efficiently. Your Sierra can exhibit symptoms when the Oxygen sensor has gone bad. Or, it may exhibit none at all. Often enough, the only sign of the problem at all is the service engine soon light being on.

What to do if your O2 sensor is bad?

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 is very rare for there to be a problem with an oxygen sensor, and not have the check engine light come on. Here are the most common symptoms of a bad oxygen sensor in your Silverado:

Can a bad oxygen sensor cause a misfire?

While a rough running engine can be a sign of a bad oxygen sensor, it is often a sign of a misfire as well. Often enough, there won’t be any noticeable signs of a bad oxygen sensor. You’ll go to get an emissions check done, and your Sierra fails the test.

Where is the O2 oxygen sensor in the engine?

Also, The (O2) Oxygen Sensor is not able to measure the air or the fuel entering the engine. Because, the (O2) Oxygen Sensor is located in the exhaust and that where it reads the actual oxygen content in the exhaust. Depending on the year; make and model of your vehicle you could have anywhere from one to four (O2) Oxygen Sensors.

What is the OBDII code on a GMC Sierra?

P0161 is a very common OBDII code that occurs in the GMC Sierra. It is typically caused by a failure in one of the elements that heat the oxygen sensors, specifically bank 2 sensor 2. Replacing the Oxygen sensor will fix the problem a majority of the time.

Why does the Check Engine light come on on my GMC Sierra?

Oxygen sensors can change the way that your Sierra’s engine runs. Most of the time, the check engine light will 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.

What causes the p0161 code on a GMC Sierra?

P0161 is a very common OBDII code that occurs in the GMC Sierra. It is typically caused by a failure in one of the elements that heat the oxygen sensors, specifically bank 2 sensor 2.
