How to Find the Causes of Infiniti G35 Mass Air Flow Sensor Problems
The mass air flow sensor is just one of the several sensors required by the Federal government to be used among vehicles. This vital component in your Infiniti G35 measures the amount of air flowing inside the combustion chamber. When this component wears out, your engine's performance will be greatly affected. To fix it, you have to find the culprits first; you have to find what caused your Infiniti G35 mass air flow sensor to break. Here are the steps that you should follow when:
The check engine light is on
When the mass air flow sensor or MAF is not working, it won't be able to send air-flow data to the vehicle's ECU. The computer then uses the codes stored in its memory to compensate for the missing info that the sensor couldn't provide. This is the reason why a fault code is transmitted to the computer, which turns the check engine light on. To verify the cause of this problem, you have to plug a scan tool in the outlet found under your dash. Wait for a few minutes until you see the code on the tool's screen. Determine what the code means by reading the car owner's manual, then apply the necessary repair to fix the defect.
The vehicle stalls
A damaged mass air flow sensor does not have enough power or voltage to work efficiently. Because of this, it loses the ability to determine the amount of air-fuel mixture required by the engine. That's why your Infiniti G35 experiences hard start ups and engine stalls. You need to use an ohmmeter in this case. Perform a voltage test on the brown-striped wire while the engine is running at idle. The sensor must have at least 2.5 volts to function. Replace this component if the reading is below those digits.
The cleaning circuit is broken
Sometimes, the cause of the problem is not actually a broken mass air flow sensor. It is a dirty sensor instead. That's why you need to check the self-cleaning circuit relay regularly. This device keeps the MAF free from contaminants. If this relay is busted, it won't give off power or voltage. Again, you need to hook up the voltage meter and get the power measurement. No power means that the relay is no longer functioning.
