What happens if your air flow sensor is bad?

What happens if your air flow sensor is bad?

If the mass air flow sensor isn’t working properly then you will be faced with one or more symptoms such as lack of power and bad fuel economy . Of course, there are many other reasons why your car might not be running properly, so today I’m going to explain how to diagnose a bad or failing air flow meter and see what’s involved in fixing it.

Can a bad mass air flow sensor trigger a check engine light?

Bad mass air flow sensor with no check engine light? Sometimes a mass airflow sensor can start to fail and even trigger engine error codes such as P0101 and P0102, without triggering a check engine light. There must be a problem with the mass airflow sensor circuit for the check engine light to illuminate.

Where do I find the airflow sensor on my car?

Usually, you’ll find it between the air filter housing and throttle body. This could be a small block or a cylindrical section mounted as part of the air duct. On some models, you’ll find it inside the filter housing. Look for an electrical connector on the air duct right after the air filter housing.

What kind of air flow sensor do I need for my MAF?

Depending on the year and make of the vehicle, you may find different types of mass air flow sensors, from the old-style vane air flow meter to the modern era hot-wire mass air flow meter. Since hot-wire technology is the most widely used today, we’ll assume that your MAF is using that design.

How to tell if your air flow sensor is bad?

Therefore the most common signs of a bad mass air flow sensor usually appear in the form of an engine that is performing badly. Here are some of the most common bad mass air flow symptoms that you will typically come across. 1. Check Engine Light appearing on the dashboard

What happens if the mass air flow sensor is not working?

The job of the mass air flow sensor is to keep track of the amount of air coming in through the air filter, so that the ECU can adjust the amount of fuel getting into the engine. If the mass air flow sensor isn’t working properly then you will be faced with one or more symptoms such as lack of power and bad fuel economy.

Why does my car not start when the pressure is low?

If it sends a signal that the pressure is low, the computer may prevent the engine from starting. If the signal was sent in error or no signal sent at all, it may indicate you have a bad sensor. Sensors play a vital role in the overall operation of your engine.
