7 SYMPTOMS a A BAD MASS AIR FLOW SENSOR, FIX & Bypass

Modern electronic engine vehicle controls can calculate the right amount of fuel to be used in a given situation. Many sensors and actuators come into play. These sensors and actuators include mass air-fuel (MAF), fuel injectors, and fuel injectors. As with all car parts, they can wear down over time. You may have performance problems with your vehicle due to a bad mass flow sensor.

WHAT IS MASS an AIR FLOW SENSOR?
A car mass airflow sensor is a device that measures how much air is entering the engine intake. It is crucial to measure the air mass to calculate how much fuel you should add to reach the desired air-fuel ratio (AFR). Although the ideal AFR would be 14.7:1 (14.7 pounds of fuel to 1.0 pounds of air), real-world AFRs can vary. A higher AFR may be required for acceleration, such as 12:1, while for cruising, a lower AFR might be necessary, sometimes as low as 22:1. A bad MAF sensor can cause the engine control module (ECM), not to correctly calculate fuel injection. This could lead to bigger problems with your vehicle.
what is a normal mass air flow sensor reading
Base on you car engine, the Mass air flow sensor reading should have a PID value around 2-7 grams per second or a 15 to 25 grams per seconds at 2500rpm.

The negative battery cable is black! Not red!

[crand]

Tell me more about those 'worst engine conditions' that a bad MAFS can cause.

[davidsalyer]

The RED wire is NOT THE negative wire in the USA.

I have driven my vt v8 Commoredore with my maf sensor unplugged for the last three years and my car drives awesome plenty of power I had just covered my check light with tape problem solved😝👍😆

[engineprojects]

Uhhh red is positive cable 1 of manny faults in this video and you can drive whitout it

[rloiffu]

20 seconds in and I alredy regret clicking on this video… fuel injectors, fuel injectors. I mean how does every carpart search end up on a video read by AI, and why… Have a nice day, mate

The MAF Bypass part of this video is absolute nonsense. You cannot just unplug the MAF, while the car battery is disconnected, the reconnect the battery - you'll get a check engine light within 10 miles. The car's ECU *knows* the NAF is unplugged!!! It can be bypassed properly, but this low quality robot-voice video has no idea how to do it properly.

red cable to positif and black cable to negetif?

[JJ-okmw]

When I unplug my mass air flow sensor there is no change to how my truck runs when I plug it back in it dies I keep getting a p0147 lean bank two already changed all plugs and coils new O2 sensor on bank two upstream cleaned mass air flow sensor truck is a 2004 f150 5.4 3 valve

So..2009 mini cooper n12 engine..I wanna change the air cleaner setup. I have a MAF sensor and was told I can ONLY use a "Typhoon" air cleaner system (only aftermarket one available specifically for my car), I cannot use an 'aftermarket' cheaper version because of the sensor. So I can't do anything else like bypassing the MAF forever?

[joelfluth]

@0:17 mass air FUEL? You should have a narrator who actually knows what he is talking about.

[Cocovlog]

Got a question my car is tuned if i will replace the the maf sensor will my tune stay ?

[heyjohnson]

Wow negative power to the batterry is normally black not red. Red is the color of positive.
