Symptoms of maf sensor nt working
Check Engine Light
The most reliable early symptom of a failing or failed MAF is the illumination of the check engine light on the instrument panel. Many types of problems may cause this light to come on, so you must have your car's computer analyzed to see if the light is related to the mass airflow sensor.
Computer Analysis
An auto mechanic can analyze a car's computer for a fee, or you can do it yourself using a digital auto diagnostics scanner. These scanners are available at most auto parts stores, and though they all work a little differently, they're generally designed to be plugged into the car's circuit box so that they can read the computer data. After the scan, the scanner will display one or more numeric codes, which must be looked up in a reference book that accompanies the scanner. If you do this and the scanner codes refer to a malfunctioning MAF, you will need to have the MAF inspected and likely replaced. Mass air flow sensors are rarely repaired, as it is usually more cost-effective to replace them.
Performance
Since the MAF is instrumental in maintaining proper balance of air and fuel inside the engine, MAF failure can cause a wide range of engine performance problems. These may include
low gas mileage
shuddering
stalling
knocking
pinging.
Other common automobile problems may also cause these symptoms, so they don't specifically indicate MAF failure. These symptoms can appear, however, before the MAF fails to the extent that it will register the check-engine-soon light.
Particle Buildup
Sometimes the MAF will begin malfunctioning because it is dirty. Although the air that passes through the MAF is filtered, microscopic particles will still get through and accumulate on the sensor. Most of the time, this buildup won't be significant enough to affect the MAF, but severe buildup can cause interference.
