RE: Help with DTC code!!!
I agree that resistance readings would be best to test the MAF if anyone has any known working values to check against that would help, also the pin out for the sensor would help. You mentioned water around the ECU water box? Where do i need to look to check this?

ignition off remove MAF multiplug resistance between 1 ( wire side ) and ground should be zero resistance,
checking for power
multiplug disconected switch ignition on and crank for a second - battery voltage between 3 and ground and do same with pins 1 and 3,
testing while engine running multiplug connected back probe the wires,
engine idling clotage should be 1.1v approx
at 3000 rpm voltage should be 1.9v approx

But run Techbod's resistance values (above) against yours.
