Testing a MAF? Is there any way to test a MAF without actually putting it on a car and seeing if the ecu throws codes? |
Re: Testing a MAF? You can watch the gps with tuner pro rt. |
Re: Testing a MAF? Sure - stick it in a flow bench, give it power, and check the voltage output against the MAF scaling table in the ECM. GD |

Re: Testing a MAF? Incidentally, if you DO check it on the car, the general rule of thumb is 1 gram per second per liter of engine displacement. So you want to see *around* 5 grams per second at a standard 750 RPM idle. To check the MAF at WOT you can then do a volumetric efficiency calculation. GD |
Re: Testing a MAF? Tanks, guys! I have two MAFs plus the one on the car. I'd like to see if the ones in boxes still work or if I should just toss them. One is a Bosch. |
Re: Testing a MAF? I guess I'm trying to see if the wire is broken. Maybe if I could apply power to the burnoff and look inside to see if the wire is glowing. If the fine wire is broken, obviously there would be no glow. If there is glow, the wire is intact. You think this is possible? if so then I could proceed to try to power it and read the signal voltage using a shop vac to get some airflow.I |
