E46Fanatics How To Test The

In this article, we will talk about the symptoms of a bad MAF sensor, location, and the replacement cost.

If one sensor is sending a wrong signal, the ECU will light up the check engine light.

A faulty air-fuel mixture will cause a lot of strange problems with your car.

A slow car is one of these things that could happen because of a faulty air-fuel mixture.

If the air-fuel mixture is too rich or too lean at this moment, your car may not start at all or just crank a little bit longer than usual.

Therefore if you realize it pours out a lot of black smoke from your exhaust pipe there is a considerable risk that your engine is running too rich, which a bad MAF sensor can cause.

To combust the fuel correctly, the engine needs 3 things the right air-fuel mixture, an ignite, and compression.

Therefore a faulty MAF sensor can cause the fuel consumption to either going up or down.

However, to properly diagnose the MAF sensor, you need to correctly measure values for your specific car engine and model, which you can find in a repair manual.

It should go up when you rev the engine and down as the engine RPM decreases; if the value is stable, there is either something wrong with your diagnostic tool, MAF sensor, or the wirings to it.

You can find out more about how to test the MAF sensor in this video.

This particle accumulation over time results in poor performance of the sensor.

Just remove the sensor head from the MAF sensor housing and carefully clean the sensor head with an electronic cleaner or a specific sensor cleaner like this one.

You can expect a total cost of 140 to 550 for a mass air flow sensor replacement, depending on the car model.

You can often do this yourself if you just have basic car skills.

One of these signs are a check engine light, lower engine performance, rough idle and changed fuel consumption.

The most common things that happen are a check engine light, bad engine performance, rough idle, and changed fuel consumption.

To know the resistance you should see on the multimeter, you can check in your repair manual for your car model.

If your engine is running fine, you can drive slowly to the closest repair workshop without problems, though.

I have been working with cars for 10 years, specialized in diagnostics and troubleshooting.

I created this blog because I was tired of finding false information on the web while looking for repair information.
