Maf Reading With Engine Off at Cora Turner blog

Maf Reading With Engine Off. Either as low as 3.5g/s or as high as 6g/s. Car's been running very rich and stalling etc, today took a look at sensors, maf reading with engine running was normal, but with the engine off and ignition on it stays at. Check maf with engine at operating temp in park at idle. The first scan tool method checks the maf sensor using the grams per second to measure airflow with the engine off. If i plug in vcds and monitor the maf sensor with the engine off its reading 2.3 g/s. The maf reading is all over the place. Something around 30 at idle should start to set p0171. I can take the sensor off the car and wave it. Should be reading around 2 g/s. Monitor the fuel trims(st plus lt). Varying the engine load by shifting to p/n or in gear, or ac on/off will result in 4 different air flow conditions. The ‘normal’ maf reading at. Since the engine is off, the number should not be very high. When the key is on and the engine is off, a map (manifold absolute pressure) sensor should typically read close to atmospheric pressure, which is usually around 4.6 to 4.8 volts. Dry crank is 300rpm, crank with fuel injection and ignition is 460rpm and doesn't go over it.

Monitor the fuel trims(st plus lt). Either as low as 3.5g/s or as high as 6g/s. This corresponds to approximately 100 kpa (kilopascals) or 29.92 inhg (inches of mercury) at sea level.

Maf Sensor Reading Engine Off

Maf Reading With Engine Off Understanding the importance of maf readings, especially at idle g/s, can be instrumental in identifying potential engine issues early on. The ‘normal’ maf reading at.
