Peskey MAT Sensor

I have an 89 IROC Vert with LB9 and have finally got it running again except cant shake SES LIGHT giving me the MAT sensor code. When car is cold starts and runs, SES light comes on with code 23. When car is warmed up, I turn it off restart and SES light doesn't come on.

Any ideas?
