Heard you can test this sensor by starting truck and pulling connection. If engine dies, sensor is good. If it keeps running, sensor is bad.
. True or false? Ken
BTW, 1992 Ranger xlt,, 2.3L.

 

MAF SENSOR

 

No, not true, but I am sure it sells A LOT of MAF sensors, lol

Only depends on the software in computer
If you unplug the MAF sensor the computer sees a Main sensor off line so may shut off spark and fuel, but wouldn't tell you if MAF sensor was good or bad
Not sure what a 1992 2.3l would run but its the EEC-IV computer so it should run either way

Generally speaking if any sensor is having a bad time computer will turn on the CEL(check engine light) and set a code
Usually MAF sensor would set Lean code

Just as an FYI
The computer knows its running a 2.3 LITER engine, so it already knows EXACTLY how much air is coming in at any RPM and throttle position, its just Math
The MAF sensor is there to WEIGH THE AIR, to get its "mass", as in Mass Air Flow sensor

Air:fuel ratio for gasoline is a WEIGHT RATIO, 14.7:1 ratio
14.7 pounds of air to 1 pound of gasoline
14.7grams of air to 1 gram of gasoline

Air weight changes a lot, sea level to 5,000ft elevation, cold day to hot day
So the air weight is important, but if its off by a bit engine will still run
Run poorly yes, run rich or lean yes, but it will run
