What Should Maf Read With Engine Off. The car should still run w/o the. I got my hands on an obd2 adapter and software (obdwiz), and looked at some values off the car's pcm/computer. Disconnect the maf and recheck the live data, with car off and on as a means of confirmation. Monitor the fuel trims (st plus lt). The ‘normal’ maf reading at idle can vary based on several factors like vehicle make and model, engine size, vehicle age and condition, altitude, and air temperature. A normal mass air flow (maf) sensor reading at idle: Something around 30 at idle should start to set p0171. A rule of thumb on a maf's air flow rate at 500. 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. Should be reading around 2 g/s. Varying the engine load by shifting to p/n or in gear, or ac on/off will result in 4 different air flow conditions. Check maf with engine at operating temp in park at idle. 2 to 7 grams per second (g/s) and rises to between 15 to 25 g/s at 2500.
