Default Air temperature switch A bank side air filter box?
Hey guys,

what is the air temperature switch on the A bank side air box got for a function?

It was fitted to engines from 64245 onwards... I wouldn't be surprised if it is a Marelli specific part...

Number is DAC5061

Any ideas? Sure, temperature, but isn't that what the B bank temperature sensor is for? As it is a switch, something must be switched on/off!?

Cheers

Damien

All I know is that my car ran poorly when it was disconnected.

Not quite the same part. What I am taking about isn't a sensor. It is a switch. A bimetal strip in a plastic casing...

But it might well be, that the switch was used on earlier models than the sensor shown in fig. 2 in your drawing...

I could see if I can find a temperature at which it activates. If 25° then it is exactly that.

The switch on the back of the A air cleaner is a bi-metal strip and closes at 75°C its function is to retard ignition at high temperature.

Seems like something that wasn't carried over to an 89.

What exactly would that accomplish in normal road conditions? Dumb it down to compensate for a hot climate/engine temp or something?
