MAF test results
Key on:
Blue-black - should read 12.6V; read 11.9 (OK, so many tests, battery is not fully fully charged)
Black: should read less than 0.5V; read 0V
Grey-Black: should read 1 to 1.6; read 1.3V
Engine running:
Grey-Black: should read 1.7 to 2 at idle; read 1.8
Open throttle:
Grey-black: should read 3V on neutral; read about 2.5 to 2.7
The ISC valve clicked when the key is turned on but does not seems to do nothing after.
So looks like the ECU talks to it, but does not get signal from the MAF???
Black wire: I was surprised to get a <perfect> 0 - what is that wire doing in the operation of the MAF - could that be that wire be cut or off somewhere?
I tested my other MAF (yes, second-hand...): they all read similar with the grey-black wire but always the black at <perfect> 0
