Hi guys, I hope someone can help me with this issue.
I have increased emission / engine service soon warning on. I had someone check the fault codes and I got 27C5 and 2739
description for 2739 says "AIR MASS SENSOR SECONDARY AIR ELECTRICAL DIAGNOSIS"
description for 27C5 says "AIR MASS SENSOR SECONDARY AIR SIGNAL"
It looks like this sensor could be a problem. Has anyone had this type of issue and had it successful fixed? and would you have a part number and diagram for this sensor?
I really appreciate any feedback on this. I tried searching the forum but couldn't find any topics on these codes.
My emission testing is due this month. Great timing
