MAF Sensor
A MAF (Mass Air Flow) Sensor is an important car part that measures how much air enters a car's engine. Think of it like a traffic counter for air - it helps the car's computer know exactly how much fuel to use for the best performance. When mechanics talk about MAF sensors, they might also call them "air flow meters" or "air flow sensors." This part is crucial for modern cars to run efficiently and maintain good fuel economy. When this sensor isn't working right, it can cause problems with how the car runs and affect its fuel usage.

Example Interview Questions
Senior Level Questions
Q: How would you diagnose a complex issue involving a MAF sensor and multiple error codes?
Expected Answer: A senior technician should explain how they would systematically test the entire air intake system, use diagnostic tools to read sensor data, and describe how they would identify if the MAF sensor is the root cause or if it's part of a larger system issue.
Q: Can you explain how you would train junior technicians on MAF sensor diagnostics?
Expected Answer: Should demonstrate teaching ability by explaining how they would break down MAF sensor operation into simple concepts, show proper testing procedures, and explain common diagnosis mistakes to avoid.
Mid Level Questions
Q: What are the common symptoms of a failing MAF sensor?
Expected Answer: Should be able to list major symptoms like rough idling, poor fuel economy, engine stalling, and explain how these symptoms relate to MAF sensor malfunction.
Q: How do you properly clean a MAF sensor?
Expected Answer: Should describe the careful handling of the sensor, use of proper MAF sensor cleaner, the importance of letting it dry completely, and when cleaning is appropriate versus replacement.
Junior Level Questions
Q: What is a MAF sensor and where is it located?
Expected Answer: Should be able to explain that it's a sensor that measures incoming air flow, typically located between the air filter and engine intake manifold.
Q: What basic tools do you need to test a MAF sensor?
Expected Answer: Should mention diagnostic scan tools, multimeter, and basic hand tools, showing understanding of basic testing procedures.
