No 5Volts on MAF :(

AAN engine.
why ?????????

[kwlw]

ECU is quite rigid in terms of power supplying for the MAF. So check cabling. Its far more often cause for trouble, than ECU itself.

I plummed my datalogger into the wiring loom near ECU plug to read 5v MAF signal at idle it will read approx 2.39v

The signal wire runs to pin number 7 on the ECU plug (can't remember the colour though). Put positive lead of multimeter to this wire and earth the other one to chassis.
