is there a fuse for the maf? I had my multimeter on current not voltage and touched my intake and the battery. Now I have a p100 code and a cel. Any thoughts....

 

Maf is powered from the same source as all the engine sensors/ecu. It does not have a dedicated fuse.

 

Does the car still run ok? Did you disconnect the maf, if so reseat the connections again. The P100 is a maf code, if it's the only code you have and the car is running ok you may try to reset the ecu by pulling the ecu fuse, or disconnecting the battery for 10-20 minutes. Then see if the code comes back.

 

car seems to hesitate a little, but i never touched the maf. I'll pull the ecu fuse and see what happens. I wonder if an arc was created between the stupid aluminum intake and the maf wire and cooked it. I guess we'll see. lesson learned...make sure you have your multimeter set for voltage before you go dicking around

 

your maf should read something like 1.7v -- dont quote me on that.

if its dead, you need a new maf.
