MAF Range

[jasegould]

Hi guys, does anyone know what voltage range the MAF works through??

Im havin probs with my idle and my car brings up the fault code for the MAF circuit :roll: Ive tested mine and it goes from 1.5V at idle to approx 3-3.5V at nearly fully open.
Thanks

sounds about right.is the voltage smooth,and when you rev it jump to 3.5v.

thought it maxxed out at 5volt on mafs
theres a big thread on gtr forum all about the sensors etc have look

Yeah, thats what i thought, the voltage curve is smooth, prob does max out at 5 but i was revving the engine by hand and didnt want to blow it up I havent got any specific data, just following general test procedure

Is it a mis-fire at idle? Mine is quite bad, especially when cold and it 'hunts' at light throttle settings. Runs great everywhere else though, F-ing thing :evil: ! Am going to try and get it for a diagnostic check the end of January cos ive changed the plugs, leads dizzy cap etc.etc. and its made no difference...........its fouled plugs a couple of times too :? . I can let you know whats the problem when i find out.

It runs fine, boosts ok etc but has a prob with the idle. Usually idles around 1500 - 2000, will sometimes eventually settle to 1000 if left.
It hunts very badly at light throttle....well it doesnt really hunt it just drops suddenly then picks up, bit different to hunting. I did a fault code check and it came up with MAF circuit.

My safc says im doing 1 ish on idle and then 4.5 on full throttle.
