duramax lbz code
 

When checking for a code when engine light came on I keep getting the response vehicle does not respond. Motor runs fine and has 252000 miles on it. I delever oil field freight. Do not like anything wrong with motor keep all maintance up perfectly. Anyone have a clue what this is?

check the fuse that powers the cig lighter it also powers the dataport

vehicle not responding
 

I found the problem. I tried a freinds actron 9580 and it showed the code. Do not know why my code reader had the problem. It was the same code I have had before. The stinking mass air flow sensor. It had always showed it before. I guess I am going to have to buy the $200 4 inch piece of plastic. I have cleaned it about 10 times!

are you running an oil type air filter?

Yes a K&N do you think that is what is causing the mass a flow sinser to mall function?

Yep i do not use oil filters on diesels...some guys swear by them but i do not

I was also thinking about a ppe redirect for routing the turbo breather hose from the turbo intake to a catch can. Have used this product or know anyone who has. It says it eliminates the oil contamination in the tubo duct and lowers engine pressure.
