Hello, Have a 2001 Sentra 1.8L auto 77,500. need to get thru emmisions test.Failed due to "No communications" with ECM. Went to Autozone to see if there scanner would work & had same results.Car runs great & no check engine lamp.Is it possible that there could be a loose connection at the ECM? Thanks

took car in to local nissan dealer & they diagnosed it as a bad ECM, They also covered the repair under federal emmisions warranty 8/80 law. Although I had to bring up the law they woundnt have otherwise.Thanks for your response.
