well the above post is true, other sensors could cause the code to trip. went to autozone today when i got off work and tested the volts for the maf plug and read as follows:
power to ground measured 11.25v
ref wire to ground measured at 5v with the acc on but engine not running
i couldnt back probe it so i tested the female connectors so the plug is getting power so the fuse isnt blown since its getting power and ive already swapped the maf so assuming it is good but i have another one that should be here by the end of the week.
when they scanned the computer the code that was read was p0102 but i have now seen two different deffinitions for this code 1. maf low input voltage, and the one from autozone 2. MAP or MAF sensor condition
here is what was printed out verbatem:
vehicles have one or more of these components. Engine load or the air volume entering the engine measured by these components. The computer has recognized a return signal error.
Probable cause
1.-vacuum hose off, cracked, or passage blocked
Engine mechanical timing condition
2. throttle body intake tube loose, off, or cracked
3. map defective
4. maf dirty or defective
what i have trouble shot so far
replaced vacuum lines and triple checked these and did the wd-40 trick to pinpoint a vacuum leak- ok
has aluminum intake tube, and checked the tube fitting for the throttle body and is on tight- ok
replaced maf already with no change and checked the voltage at the maf-ok
so could be a vacuum line still, or the map sensor
