Code 23 need help!

well i got a SES light while driving yesterday so i pulled over to see if it was something serious. i turned off the car, got out checked everything.. looked good. so i turn the car back on and the light is off now. didnt really think much of it, just wanted to get home at this point. so i get home and check the codes and i have a code 23 which is manifold air temperature sensor. the book i have says it means.... "Poor electrical connection, open or short in circuit; ;defective MAT sensor; defective ECM. i really hope its not a defective ECM, but how can i go about checking these things to see what exactly the problem is? thanks!
