Maf Sensor Reading With Engine Off at Rhoda Kenneth blog

Maf Sensor Reading With Engine Off. If i plug in vcds and monitor the maf sensor with the engine off its reading 2.3 g/s. The maf sensor simply measures the mass (amount) of air coming into the engine so that the pcm can add the correct amount of fuel. Acceptable but not perfect when cold, really bad when hot. It also hesitates off a stop when hot. The most common symptoms of a bad mass air flow sensor are engine performance issues such as rough acceleration or rough idling, along with a check engine light on. The first method to test the sensor is to read the maf sensor grams per a second data with the engine off. The car has a rough idle. I plugged in my obd2 reader and maf is reading 0.29 g/s when engine is off. I put the ignition on but the engine is off. Hi, my 2002 corolla has a p0171. Since there is no air flowing pasts the sensor, the reading would be very low. I can take the sensor off the car and wave it through the air and get the reading to fluctuate, and the reading is exactly the same between. A rule of thumb on a maf's air flow rate at 500 rpm is 1 gram per second per liter of engine displacement.
