My scan tolls reports the MAF sensor, but I have replaced some used sensors, but the sensor does not send signals to the ecu, but I got 12v, 5v, 5v and ground going into the sensor, the connector has 6 wires en-trying, I am able to read 12v, 5v, 5v, and ground. I checked out put when car is idling to see if I have return signals from the other two cables, but nothing. Please can I get an EC and EG for, or just the MAF wiring diagram for voltage reading.

Hi,

First, this vehicle isn't offered in the US, but I will try to help. As far as what you have described, the only thing that makes sense is the MAF sensor is bad. If you have the voltages indicated and ground, either the sensor is bad or you have a broken signal wire. Have you checked the signal wire for continuity?

Let me know.
