what is a normal mass air flow sensor reading
Idle rpm 20 kghr. Will change MAF air flow readings but the readings should fall within a given range at the same engine speedtemp.
Manifold Absolute Pressure Map Sensors
An Auto-Scan is always helpful.
. The reading considered normal for the mass air flow sensor should be between 2 to 7 gramssec and 15 to 25 grams. The engine computer uses this information to determine the air-fuel ratio needed for combustion. The later model units like those on a 3800 V6 should read.
This Codes full read out is. P0101 - Mass Air Flow Sensor Circuit RangePerformance. The older AC Delco MAF sensors like a 28L V6 should show a steady reading of 30 to 50 Hz at idle and 70 to 75 Hz at 3500 rpm.
This sensor is sometimes integrated in the MAF sensor Mass Air Flow Sensor or is located in the air filter duct housing. If you ask me engine at idle no load at sea level you should see on a 20L engine about 34 to 36 maybe a little more 38gsec. The MAF frequency at idle for me is around 17-1800 if i recall correctly.
The engine computer uses the MAF sensor signal to determine how much fuel needs to be injected to. A defective MAF sensor can cause engine stalling a rough running engine and a check engine light for. How do you mean.
The P0113 code in simple terms means that the ECU. With the engine at normal temp 80-100C and airbox in place VERY rough readings should be. Output signal of MAF made by BOSCH is a variable voltage in.
Readings may vary based on. The mass air flow MAF sensor reads the air flow entering the engine. In answer to your question 42 to 6 is correct MAF reading for warmed up idle remember its calculated PCM looks at IAT and MAS sensor frequency to calculate the weight.
You want your MAF histograms to be as close to 0 as possible when everything is. A mass air flow sensor determines the amount of air that enters inside the engine this information is then in turn communicated to the engine computer.
