I think it should measure some resistance. If you have an OBDII plug, some scanners will read the air temp sensor. But I don't know if the 95 had OBDII yet.

Does anyone know what exactly the air intake temperature controls? The early W124s had no AIT in the air boot. When I read my codes, it also said mine was bad too. But the car runs great.

It's for the EFI system.

Obviously. But what EXACTLY does it control/influence in the FI system?
