Shorty after reinstalling it, and resetting the cel by removing the negative battery terminal ect... the cel came back on . Is it possible that the sensor could be bad despite the fact it didn't show any signs of contamination ? Any thoughts ?

p.s. Prior to checking the MAF, I removed the air intake filter and thoroughly cleaned it .

Yes it could be a bad MAF. other thing beside the one you addressed is the plug might be loose? broken or shorted wire? DME could be bad but rare. Try leaving the battery cable off for a much longer time such as an hour then drive it and see if you get another light. the code is saying that the voltage is much lower than expected from the maf which is air flow.... try unpluging the maf and drive it if there is no difference you might have a bad maf .

I am in a similar situation with my MAF (minus the cel) and I am not sure what to do. I tried cleaning it to no avail. I am still getting a rough idle and no cel. I am thinking that I will have to order a new one. I would like to avoid doing that if possible but if it has happened to others and is the best solution I will have to.
