While trying to trouble shoot an issue, I came to the point where I needed to check the resistance of the MAF sensor between the THA and E2 terminals.
If I check using my multimeter (Fluke 8062A) in standard ohm measurement mode, I get a reading of non-continuity.
However, if I check the same terminals using the auto-ranging ohm measurement mode, the resistance reading is within specifications.
I have validated these results with a second multimeter.
From reading the manual with my multimeter, the only difference I can see between the two modes is that the auto-ranging mode uses "enough voltage to turn on semiconductor junctions." While the standard mode does not.
However, in looking at the electrical schematic in the FSM, it does not appear that a junction is present that needs to be turned on, so I am uncertain about this result.
Can anyone tell me which reading I should rely on as a test result?
Thanks,
Tom
