I have a 2000 ford F150 4.2L V6
I need to know what the 4 wires on the MAF Sensor are.
1. Red = POWER ?
2. Black = Ground ?
3. Blue = Sensor
4. Yellow = ecu ?
<o></o>
The above is only my GUESS does anyone know for SURE ?

 

It has two sensors in it, MAF for airflow and it also has a barometric pressure sensor. @ filaments. At least my 01 5.4L did.
I do not have a wiring diagram in front of me right now.

 

this is what I have found out




Pin 1: Not used
Pin 2: (Rd) Power (Hot in start or Run)
Pin 3: (Bk/Wh) Ground
Pin 4: (Tn/LB) MAF signal return
Pin 5: (LB/Rd) MAF signal out
Pin 6: Not used


and this is correct as i have checked it against my truck wires.

having said that pin number 4 i take it is the wire that sends back the infomation to the pcm ?
is that right ?

 

No, pin 5 is the signal output. Pin 4 is sig rtn, essentially ground.

BTW, the most common reason noobs ask for this info is so they can install their ebay resistor mod. If this is the case, throw it away 'cos you got scammed.

Yeah what do you need to know this stuff for.. if you dont mind me asking?

 

... I forgot to mention the other reason, that "MAF Enhancer" for the run-your-car-on water crap.....

 

Well thanks for the information, the sad part about this is that STEVE you’re so CLOSED minded that you can’t take the time to think if it is doable.I can tell you from personal experience after installing only the hho cell and no other mod’s it has taken my truck from 12 mpg up to 15.5 so that’s a 30 % gain, and no its not from paying attention to my driving, this has been an ongoing thing now for over 5 months. <o></o>

For those of you who my live in the Florida area, ill pay for the gas it takes you to get to Orlando so I can take you on a test drive so you can see for yourself. If it works you pay for the round trip gas, if it doesn’t ill pay for the whole trip. <o></o>

Oh, puullleeeeesss.

Dude, go away. The HHO stupidity has been well debunked.

 

Think about it: Ignorance can be addressed through education but you can't fix stupid!......guess you are a total losssss ..l..

 

My truck is stock with the exception of the K&N air filter and the DiabloSport Predator tuner. Since February of this year to present day I have seen my mileage improve from 12 MPG to 17 MPG! Wait a minute, that has absolutely nothing to do with HHO injection and is better than your own results. How is that for debunking this nonsense?

 

Amazing John, no snake oil or anything?

 

Can't We All Just Get Along

 

Nope, just changed plugs this year, but I still have a occassional high load misfiring COP and I plan to replace the lot of them soon.

BTW, this is getting along!

 

Our new Ford COP’s, the Sultans of Spark(S.O.S.), have
been designed with both durability and performance in mind.
Please see them at:

Quality was the main feature we stressed when we went to the
drawing board on these coils.

 

I was thinking about those when I saw your reply to someone else. I will definitely keep these in mind. Any further discounting available for FTE members?
