Where is the mass airflow sensor located on a car?
The mass airflow sensor is mounted towards the top of the engine, where it’s in the path of air that has just passed through the engine’s air filter. An incorrectly installed (or missing) air filter can damage the sensor by allowing harmful particles to make contact with it.
Can you clean mass air flow sensor with MAF cleaner?
These are found in some Toyota, Mitsubishi, and Lexus vehicles and can’t be cleaned with MAF Sensor Cleaner. Turn the engine off, remove the keys from the ignition, and let the engine cool.
Why is my mass air flow sensor not working?
The P0171 refers to a possible lack of fuel pressure, a leak in the intake air system, or a possible vacuum leak. The P0102 also leans towards a leak in the intake air system. It is possible that there is a problem with a BARO (barometric pressure) sensor that is reading faulty.
Why is the MAF sensor on my car dirty?
A possible cause of a dirty or defective MAF sensor is failing to change your air filter, or installing the air filter improperly. You can try to buy a can of MAF sensor cleaner for $10, but a word of caution as these sensors are very fragile. A new sensor can cost between $75 and $200, depending on your car model, and is easy to install.
How to replace the mass air flow sensor?
Press the red clip slightly to unlock it. Unplug the electrical connector from the mass airflow sensor. Remove the screws that hold the mass airflow sensor in place. Remove the sensor. Install the new MAF on your Chevrolet. Tighten the screws so that they are snug. Plug the electrical connector until it locks in place.
What causes rough idle after replacing mass air flow sensor?
Replaced air filter and maf sensor. Problems with vehicle turning off seemed to go away but now I have a rough Idle. Car will drop below 1000 rpms and then rev back up to over 1500 like it wants to shut off. Idle problems seem to go away when maf sensor is disconnected. Car throwing codes p0171 and p0102.

How to check and replace an oxygen sensor ( air )?
A P1155 or P1135 code indicates you have a bad sensor. This is common in Toyota and Lexus cars and trucks. Learn how to test the air fuel ratio sensor to see if it is bad, and then learn how to replace the bad sensor. Nice O2 Sensor Socket Kit: http://www.amazon.com/gp/product/B005…
Your vehicle’s engine needs to know how much air is coming in so it can optimize the fuel ratio for maximum performance. Your mass airflow sensor (MAF) measures the amount of air coming through the intake, so it knows how much it’s bringing in. The MAF sensor is often located on the intake hose between your intake manifold and the air filter box.
Can a faulty crankshaft sensor cause a car to stop?
The crankshaft sensor is necessary for your car engine to run on most car models. You also have a camshaft position sensor on some car models, which the car uses if the camshaft sensor is faulty. Here, a faulty crankshaft position sensor may not cause the car to stop entirely.
What kind of sensor is in the engine manifold?
Your manifold absolute pressure sensor (MAP) sensor does exactly what it sounds like it would do – it measures pressure in the manifold. This takes your mass airflow sensor one step further by measuring how much air is actually making it to your engine.
Why does my car have a coolant level sensor?
That’s why most vehicles come with a coolant level sensor, that way, you can avoid problems before you hit the road. If your vehicle doesn’t have enough coolant, then the coolant level sensor will light up the check engine light – and sometimes it will keep you from starting your vehicle.
Can a car run without the mass air flow sensor?
The mass airflow sensor is a key sensor in your car. Your car has a lot of sensors, and this is just one that helps your car run properly. That brings up the question of can your car run without the mass air flow sensor? In this article, we will look at what happens when you disconnect the mass airflow sensor.
What happens when you disconnect mass air flow sensor?
That is because the numbers the computer generates are for brand new engines, and conditions change with the engine as it ages. By letting the mass airflow sensor make the readings, it allows for the most accurate numbers if it is working properly. So, now you know what happens when you disconnect the mass airflow sensor.
Why is my airflow sensor not working on my car?
Also, if the computer isn’t the issue, then it means one of the other sensors is probably off if the car isn’t able to keep running without the mass airflow sensor because the sensor was helping the car compensate for the other issues that it was having.
The crankshaft sensor is necessary for your car engine to run on most car models. You also have a camshaft position sensor on some car models, which the car uses if the camshaft sensor is faulty. Here, a faulty crankshaft position sensor may not cause the car to stop entirely.
