97 Tahoe - Fuse Location

[leboyd]

I looked at all the fuses in the door panel. They all look good and the metal ones tested good with ohme meter.

 

I *REALLY* need some help on this one! I have no power at the high-power side of the MAF. I know +-12v should be at the MAF when the truck is turned on, but I have 0v.

 

There must be a fuse somewhere...

 

Thanks,

Larry

Look under hood. it may be in that fuse block.

Check the connectors at the PCM. According to the manual you actually need a scan tool to check the MAF.

Underhood fuse/relay center, fuse #15, 20Amp, ENG1 fuse.

 

What exactly are you trying to fix. What terminals are you checking. Don't remove fuses and check them with an ohm meter to check the fuse. Ground one side of a test lamp, turn the key on and touch the other end of the lamp to each side of the top of the fuse. If both sides have power fuse is good. If one side does and the other doesn't, fuse bad. If neither has power the the fuse block isn't getting the power it should. It gives you alot more to work with this way.

Sparks,

 

Thank you for the information. It was exactly correctly and the fush was blown. Once I replaced it, I had full voltage and my codes (P0102 and P0340) went away.

 

Thanks again!
