Tamper resistant torx tool for MAF ?

[CrazyHorst]

All, running in "backup mode" with the MAF sensor unplugged on my 2000 GTP.

The new sensor is ordered, I noted "tamper resistant" torx fasteners on the sensor body.

I checked the archives and the repair section without a clear line on where to get the tool.

Some ideas are: order one from McMaster carr, get from AutoZone (et al) or break out the center post from the torx recess (!!) and then use standard tools.

Any others?

Sears. Size is T20.

Yeah, I have a whole kit of snap on bits and a screwdriver. I don't think it was very expensive if I remember right.

when my MAF went bad, i bought a set of tamper proof bits (kind of like an allen wrench set) at Auto Zone. If i remember right, i think the set was like $7.00

Also try MCM Electronics for the kit of anti-tamper screws for like $7.95. It is a good place for getting tools.

Just as a followup I resolved this problem a different way. Local AutoZone could not find the set in their computer despite me providing the part number from their website. Called the regional office to find there were 3 available in the area but they didn't know where but I could "order" them to the local store which would take a couple of days.

Not having sufficient patience and not wanting to drive all over the place, I got out my dremel tool with a "dental bit" and the problem was resolved in under 5 minutes. Reduced the anti-tamper posts to metal flake, blew off the flakes, and the normal T20 bits worked perfectly.

Thinking more about this, I think the throttle body is a purchased assembly from Hitachi with the MAF already installed and they didn't want other plants moving/swapping sensors around during repair activities. Other than that I can't think of a good reason for it.

Also of interest is that while running with the MAF disconnected I had no SES activity (around 700 miles total). I do know the SES is working as I had a solid light before I replaced the crank sensor and ICM. The light turned itself off after those two sensors were replaced.

Yeah, I bought a ZZP stage 1 t-body which came with regular allen bolts instead of the tamper proot t20's.

So with your MAF unplugged for 700 miles, the SES light did not come on?..... Interesting!
