How To Tell If Your BMW X5 MAF Sensor Is Failing?
What’s a MAF sensor?
It stands for Mass Airflow Sensor.
Its job is to quantify the air entering the engine.
The ECM uses this data to determine the amount of fuel that needs to be injected into the engine.
A bad MAF sensor can make your BMW X5 unroadworthy.
BMW X5 MAF Sensor Failure: Causes
Following reasons are predominantly responsible for MAF sensor failure in BMW X5:
Airborne contaminants Disconnected wires Defective measuring elements Short circuit Lifespan
BMW X5 MAF Sensor Failure: Symptoms
Hesitates to accelerate
Sluggish acceleration indicates that your BMW X5 engine is starving for fuel.
It happens when the ECM restricts the fuel supply to the engine due to inaccurate MAF sensor data.
Engine won’t start
Restricted fuel supply due to a bad MAF sensor makes it difficult to start the engine.
You might be able to crank the engine, but it won’t start.
Malfunction indicator lamp is on
It is one of the indisputable signs of a problematic MAF sensor in your BMW X5.
A defective MAF sensor can make the engine run rough and struggle to accelerate.
When the computer detects the issue, it would immediately turn on the check engine light.
Black exhaust smoke
The emergence of black exhaust smoke instead of thin white smoke is another sign of a bad MAF sensor.
Combustion of the toorich air-fuel mixture is the reason behind the appearance of this exhaust smoke.
Bad gas mileage
Inaccurate data provided by a bad MAF sensor make the ECM dump more fuel than needed.
As a result of this, fuel consumption would skyrocket.
Key Takeaways
A bad mass airflow sensor can put the ECM in jeopardy.
So, if you are noticing signs of a faulty MAF sensor in your BMW X5, get it replaced.
