Code 157 Mass air flow sensor below minimum voltage.

I know what the codes are for ,but I am unsure about pin pointing the issue....do I replace the MAF???Or do i need to figure why the voltage to it is low??

 

I would start with just cleaning the MAF sensor with MAF cleaner. The majority of MAF related codes and issues can be resolved by this simple cleaning. CRC has a new MAF cleaning spray that is available at almost every auto parts/retailer store.

 

i have cleaned the MAF a few times now with no luck........i guess ill just have to get one and hope for the best
