This is because the computer in the car if it does not receive a reading from the mass airflow sensor will estimate and supply a number that it thinks it is supposed to have. It is imperative that you know the correct way to disconnect a mass air flow sensor so that nothing else in the system gets damaged.
How to Remove a Mass Air Flow Sensor.
Remove mass air flow sensor. Symptoms of a Bad Mass Air Flow Sensor 1. Disconnect the negative battery terminal. Unplug the electrical connector on the mass air flow sensor.
Use a flathead screwdriver to unfasten the air intake hose clamp at the throttle body. Remove the clips securing the. Inspect the MAF sensor.
How to Remove a Mass Air Flow Sensor. Locate the air intake and air box. This is called the air cleaner assembly and will typically be located on the passenger side of the engine.
Mass Air Flow Sensor. Step 2 - Release the safety clip and gently pull the connector from the sensor. Step 3 - A clamp is used to attach the sensor to the air intake tube use a screwdriver or small socket and loosen the clamp.
Loosen or Remove Clamp. 1 Disconnect the negative battery cable. To remove the MAF sensor first disconnect the wire harness plug then.
2 Disengage the wiring harness connector from the MAF sensor and if necessary the IAT sensor. 3 Loosen the engine air cleaner outlet tube clamps then remove the tube. Well the answer to that is no.
If you disconnect the mass airflow sensor then the car should keep running and still be able to start normally. This is because the computer in the car if it does not receive a reading from the mass airflow sensor will estimate and supply a number that it thinks it is supposed to have. To clean or replace your mass air flow sensor you need to disconnect it from the air flow system of your engine.
The mass air flow sensor is located behind your air filter housing toward the rear of your engine. It is a square-in-shape attachment that is bolted onto the air flow tube. The sensor is also connected to your cars electrical system.
It is imperative that you know the correct way to disconnect a mass air flow sensor so that nothing else in the system gets damaged. Unclip the harness connected to the middle of the MAF. The clip can be removed using your thumbnail.
If it wont pop. Here you have a choice. You can either remove the sensor from the housing or remove the housing and sensor as a unit.
If you are choosing to remove the sensor only which. Lift one side up first. Lift up the other side and remove the whole cover.
Locate the Mass Air Flow Sensor towards the back of the engine. Disconnect the wire harness plugged into the MAF. The mass air flow MAF sensor part of your vehicles electronic fuel injection system is responsible for calculating the total amount of air entering the engine.
A faulty MAF sensor can cause your vehicle to run too rich or run too lean. Youll notice if the tailpipes eject black smoke or when the engine runs rough or backfires. Locate the mass airflow sensor near the engine air filter housing.
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 MAF sensor screws. Most mass air flow sensors use clamps on each side to connect to intake manifold air duct. Loose both clamps using the adequate screwdriver and remove the sensor.
Loose both clamps using the adequate screwdriver and remove the sensor. How to Clean a Mass Air Flow Sensor 1. Turn the engine off remove the keys from the ignition and let the engine cool.
Locate the mass air flow sensor by. With the sensor unplugged loosen the clamps and any brackets holding it in place. Slide the sensor assembly away.
Place the sensor on. Unplug the mass air flow sensor electrical connector. Remove the two screws that hold the MAF sensor secure and remove the MAF sensor.
Spray 8 to 12 spurts of MAF sensor cleaner on the exposed plate. Allow the MAF sensor to dry and reinstall. Place the sensor in a plastic bag and rub it with alcohol to clean any dirt on it.
The second technique is to buy a mass air flow sensor cleaner spray from a nearby auto store and use it to clean the sensor. One recommended cleaner is the CRC 05110 Mass Air Flow Sensor Cleaner 11 Wt Oz. Which can be found on the link on Amazon.
A mass air flow sensor MAF is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit ECU to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure.
In automotive applications air density varies with the ambient.
