ok my original maf had a bigass crack on the top, and was throwing p102, so i order one from ebay, install it same thing. i contacted the seller, and they sent me a new one no hassle. i install it same problem errrr! so this is like the last problem with the car n icant figure it out any suggestions, i checked the pigtail and about 6 inches of wire and it looked ok so idk

 

is it still throwing the code after driving awhile or disconnecting battery for awhile? the code should clear after driving a bit and seeing no problems. any symptoms?

 

yea i did both, i think its my upper intake because it has a couple small pieces broke off, i found that after taking a very close look

 

I had the same problem, and the mech. asked for 450$ replace the maf assembly. But had the sensor signal checked by another guy, and the problem was that it gave 0Hz sometimes, causing the mil to go off..! obviously it was a prob w/ the sensor, replaced the sensor, and it worked fine. On the otherhand, if the maf sensor reads less than 1200Hz, try spraying som alcohol near the intake while the engine is running, and if the sensor signal changes drastically, then you got a crack somewhere..!!! (you need to find som1 with a good obd2 scanner .. )

 

All air must pass through the MAF before entering the throttle body. Any leaks will cause problems. Check the 20 Amp ENG SEN fuse. At the sensor connector check for 12 Volt at the PNK wire, Ground on the WHT wire, and signal on the YEL wire (H.F. AC sig. may need a scope to actually see it). Also make sure the YEL wire is not open or shorted to ground.

 

I'm going to refer you to the anyone want a challenge thread my car had same issue if car starts running weird ecm is dying new one with tune cost me 190 was cheaper then Maf sensor lol

 

lol i kinda thought that the ecm could be goin out because of how old it is, so did you buy one and send it off, or did u buy it from a tuning company?

 

um my maf screen isnt there, could this cause the code?

 

I ordered through my buddies repair shop for a discount and he has a local programmer

 

o ok thank ya
