MAS problems

[drifter148]

Can some one tell me if there is a way to test a 2g mas? My TMO says that I have a air flow sensor (code 12) problem but this has happened before and I want to verify that the 2g mas is okay after I test the wires. If there is a thread out ther covering this a link would be great too!

 

As far as I know, the only things you could check are:
1:+5 volts on the Green/Red wire (these are the original GVR-4 harness-side wire colors)
2:ground on the Green/Black wire
3: the Karman output frequency comes out on the one Green/Blue wire (the one that used to go to pin 1 of the connector)
Do you have an AFC that you can monitor the frequency before it gets to the ECU?
Thats about it. I don't really think there's anything else to test that would give you error code 12. Does the car run?
