pulled a code for my maf and tps having low voltage or low input or something along those lines. i got codes 22 and 34. does that mean i have to replace them? thats what i did on my last camaro and it fixed the problem, just wondering if there was another option.

 

TPS can be checked with a digital volt/ohm meter - a search will yield you the resistance levels you should have. But in the end I think it has to be replaced if it is bad.

MAF can be cleaned sometimes - auto parts store sells MAF cleaner and throttle body cleaner - might try it, won't hurt and cheaper than a new MAF.
