I got a code 12 today, which is the MAF. on this site, http://www.robisonservice.com/servic...ouble.asp#1990
it says that the code could be due to a bad connector.
I pulled the plug off and the unit has 5 tabs, while the plug only had connections for 4. Is this how it is supposed to be?
I tested the voltage back in March and it was within spec. Is that the only way to test the unit to make sure it needs replacing?
