Normal MAF sensor values
I'm fighting an issue on another thread
https://www.ford-trucks.com/forums/1...n-driving.html
I'm looking at my MAF sensor, i was wondering if anyone knows or can point me in the right directions of the normal voltage values it should send to the PCM under normal operation.

Have a read here & let us know what you find. http://easyautodiagnostics.com/ford/...sensor-tests-1
Do you have a ELM scan tool, if so & your using FORScan test software, it would be easier to monitor what is going on with the MAF & IAT sensors.
Our MAF sensor has a built in intake air sensor in the intake air flow channel so maybe you were probing it & the MAF sensor, who's resistance will quickly vary with changes in air flow. It'll also change with the multi-meter test leads attached, as the multimeter battery test voltage heats the MAF sensor wire & it's resistance changes as it warms up. So, about all we can determine from a MAF sensor resistance check, is if it's open circuit or not. Sounds like yours isn't open circuit.
Exactly what were you doing when you were able to reproduce the engine cut out during testing?
