IAT SENSOR

2008 Saturn Astra

Engine Performance problem
2008 Saturn Astra 4 cyl Front Wheel Drive Manual 7500 miles

I was wondering what the wire colors were for the signal and ground on the IAT sensor. There are 4 wires coming off of it.

Brown/green is IAT sensor signal

Black/violet go to ECM low reference

green/white mass air flow sensor signal

red/blue go to intake manifold solonoid valve
