My credo
What's the worst that could happen?
I've been chasing an issue with my MAF for awhile now and the the other day I was futzing with hoses to see if there was a leak somewhere. Wiggling the hoses on the canister caused one to break. I replaced it and --- for now-- it seems like the MAF issue went away. Only went for one test drive yesterday and will take another today.
My question is can this canister cause code 157 Low voltage MAF?

This is the charcoal/vapor canister, isn't it?
Thanks
