[:@] My car is now throwing this code at me.

PO102 MAF or VAF A circuit Low input

Please help thanks

 

Hows it running?

Have you tried cleaning the MAF sensor wire?

 

well i just got it chipped with GIAC. Before that i Had a problem with boost and it threw out a code, so i cleaned the maf sensor( can't remember the code # think it was po171), after I cleaned this out my boost was back to normal(10psi), now that I have gotten it chipped sometimes it goes to 18psi, but mainly it stays right around 12-14psi. I don't think this is normal most people that I have read with GIAC chip are around 17-19psi.
I don't know what to do.

 

Sounds like a bad connection to the maf, check the wiring harness, maybe clean it, or possibly a bad MAF.

search box at bottom, put in P0102 get about 100 threads with same problem.

Check the connection first, thats the easiest thing to do.

 

P0102 is wiring short to ground on the MAF

 

I had that code 2 years ago. I had the MAF replaced with a remanufactured one from;

www.ecstuning.com

The code has not returned.

 

Thanks, I will either try to fix the connection or buy a new one[:@]

 

I had this happen and I had the wiring traced all the way to underneath the dash... took HOURS.. turned out to be a bad maf... when the maf reads 0 it gives out this code.. when it reads bad numbers.. either too high or too low.. its another code...

swap the maf and you should be good to go (after clearing the codes ofcourse)

Peace

 

cool thanks guys i will try all of the above

 

seems like swapping the maf should solve the problem. but dont bother clearing the code. if the MAF was the actual problem, the ECU will detect that the problem is fixed and shut the light off on its own. if it doesnt go off within a couple of days, ide say the MAF wasnt the problem.
