In some applications the PCM translates the base data input into a grams-per-second GPS data line indicating the metric weight of the air flowing into the engine.

. Bottom line the PCM uses the MAF to determine the injector pulse width how long to squirt fuel. With the engine at normal temp 80-100C and airbox in place VERY rough readings should be. Httpsamznto2DTTDuJEngine light is often triggered by bad or dirt.

Perfect AFR sb 147 grams. Whats the normal MAF reading at idle. It is intended to be insensitive to the density of the air.

MASS AIR FLOW SENSOR TEST Scanner Used in the video. If you suspect a MAF sensor problem scan for any fault codes. The fact that your engine is capable of meeting and exceeding the minimum boost pressure tells us that the engine is running well.

The article in illogicTCs post is very good reading. 05152022 Auto 4 Mins Read. A normal mass air flow sensor reading will vary between 2 to 7 gramssecond and between 15 to 25 gramss at 2500rpm.

The MAF sensor simply measures the mass amount of air coming into the engine so that the. Depending on engine size the MAFs PID value should be between 2 and 7 grams per second gs at idle and rise to between 15 and 25 gs at. HOW TO KNOW IF MAF SENSOR IS BAD.

A clogged up air filter or plugged catalytic converter can also cause lower air flow. In conjunction with the air temperature sensor the MAF sensor. Idle rpm 20 kghr 1000rpm 30kg 2000rpm 60kg Readings may vary.

Discussion Starter 1 May 3 2019. No change in the reading or a reading that makes no sense could indicate a problem with any of these sensors. The Rpm is around 650 at idle.

Low mass air flow readings do not necessarily indicate that the sensor is defective. What is a normal mass air flow sensor reading. A mass airflow MAF sensor works on the principle of current flow to the wire and the amount of electricity required to keep it warm.

Mass air flow MAF sensor is a sensor that detects the mass of air flow that enters the engine. This sensor as I mentioned above is located before the air filter. Almost exclusively caused by a stuck turbo.
