Re: codes
Yes you're reading the code right at 23.
I'd check the wiring over very carefully first before diving into the sensor itself. By location, it's expeosed to quite a bit of heat and moviement. The intake plenum is compirsed of two, three really, pieces, the upper which has the throttle body attached to it at the front, runners (2 on each side) that route the air into the final piece, the lower plenum, that houses the fuel injectors and blends the air and fuel together. |

Re: codes
do u think maybe the air cleaner could be causing it? i noticed when i got it back from the shop. i had the fuel lines fixed and the air cleaner had been taken off i fixed the hose from the air cleaner to the manifold and replaced a hose that was off fron under the air cleaner. i never had a problem with it tell i took it back to the shop that did the fuel lines.It runs really good like nothingis wrong with it just the light comes on. any thoughts?

Re: codes
Any issues with a air intake hose would normally cause a mass air flow sensor fault by way of unmetered air getting inot the inthe intake as a vacuum leak.
