Hi, I'm going to make up a test rig to test MAP sensors to see if they are faulty. As far as I'm aware the input voltage is 5V, does anyone know the output voltages from full vacuum up to 25psi boost?

Thanks in advance

 

Depend what Map sensor you are testing.
there are different models.
the workshop manual gives expected idle and engine off output voltages which will give a good indication if faulty.

I've attached a foot pump with pressure gauge before now....

 

When you say 'Workshop manual', is that a Subaru item or just Haynes??

Whatever it is, where can I get one?

Cheers.
