Fuse for MAF sensor

[Conroy22]

I have no voltage on my sensor. Which fuse supplies power to the sensor?

I forgot to mention it is a 3l ZD30 engine.

Are you talking about the white wire that should have around about 12 volts, when the ignition is on?

If it doesn't, you may have a faulty ECU relay.

Does the engine run?

That's all sorted now. I had an extreme loss of power but after changing the fuel filter, the air cleaner and cleaning the MAF sensor the problem still exists. Each one of these things I did made some difference but there is still no power in the engine. It idles well and a light touch of the throttle feels OK but a standing takeoff is pathetic and it I have to go more than 200 yards before I reach 20k. Where I get the vehicle serviced they think it is the injectors. Any ideas . It is a 2002 model and has been going well until this rather sudden problem.
