Recently, I had an air mass filter sensor installed in my car (a 2011 Nissan Altima), plus a new air filter. However, the check engine soon light came on afterward. What can be the reason?

There are a few reasons the check engine light could have come on after having an air mass filter sensor installed in your car, as well as a new air filter. One possibility is that the new air filter is not compatible with the air mass filter sensor. Another possibility is that the installation process was not done correctly, and the air mass filter sensor is not working properly as a result. Finally, it is also possible that the check engine light was already on before the new parts were installed and that the installation simply triggered the light to come on. If you are unsure of why the check engine light is on, it is always best to take your car to a mechanic or dealership for diagnosis and repairs.
