Ok hello guys a couple of weeks ago I got a code realted to maf, well it popped up agian p100 cant find it in book. this is the second time it has come up. does that mean my maf is crapping out.. thanks

 

There is a complete code list on my Tech Page.

The code is for insufficient signal activity, meaning the pcm is not seeing enough of anything going on. Could be the sensor or could be that it is not getting power. It is somewhat common for the pink power wire to go dead, so check it for 12v when the key is ON.

FYI, you might get more responses if you would just post your question and not call out me or Fred. There are lots of people on this board that can help.

 

The code I get is vaf or maf malfunction checked the voltage to the harmess well unplugged it it read 6.6 volts is that ok. and where do i get 12 volts how would I check that. Thanks again.

 

With the connector unplugged and the key ON, you should have 12v on the pink wire. 6.6v is a problem. Make sure the engine sensor fuse is making good contact in it's slot. You may have to end up tracing the pink wire back to where it is spliced. It is somewhere near where the transmisison harness breaks out of the main harness.

 

Now you are saying just the pink wire well I did what the book says unplugg the harness and measure the voltage. Now you are saying measure the pink wire how do I check it do I tap in the wire itself or do I just measure it thru the holes on the connector , and what ground do i use.. The book says 4 to 6 volts by tapping in the holes on the harness you are saying just the pink wire sorry im confuse..... Ok I sorry i got it Thru the connector with the key on Black ground pink hot I got a reading og 11.59 volts so that good so the conclusion is that its my maf. right ..

 

Wow, that's a lot of rambling. Anyways, if you're getting about twelve volts, on the pink wire, from what shoebox (the guy is practically a god when it comes to these cars) said, it's probably your maf. He said it's either that or it isn't getting power, you say it's getting power, so it's probably the sensor itself. Don't really know, but if Shoebox says it, it's darn near bound to be right.

 

You ask a specific person for help, he gives you the exact answer, and then you appear to be complaining that he told you two different things. If you carefully read what he said, it is perfectly clear. If you already have "the book", and prefer to follow "the book", why are you asking us?

 

Sorry I just had got mixed up with the voltage readings... I went by the book to measure the harness voltage, thats where I got mixed up. It did not say anything about the pink wires voltage sorry I bothered you. I was in a hurry to go to work when this happened. Now the question it is my maf so the question is can I drive it because tonight when I was coming home it was stumbling when I got on it, is it ok to drive.. thanks injuneer.
