3 Bar sensor

[EcoBrick Bob]

The stock MAP sensor is a 2 bar.  The 3 bar sensor Torrie sold me to be used as a MAP sensor is identical (same part #) to the 3 bar sensor in front of the throttle body.  Both read info and translate it into a voltage signal. ECM reads that signal voltage as it relates to the sensors purpose.

So......if I am running a tune and my Bluetooth OBD program shows a steady 15.4 psi, am I better served by getting a 3bar?

[EcoBrick Bob]

Not necessarily... Only if you are planning on a more aggressive tune. And.. switching to a 3 bar sensor requires your tunes to be modified to accept the 3 bar data by the ECM.

Anyone have a P/N for the 3-bar mapV sensor please. did a search, did not see it anywhere.

[Boggus]

I have ordered one, if your answer does not appear - once mine arrives I will post it.

Maybe? AA5Z9F479B - Sensor 3.5 LITER W/TURBO

Thanks!

There is no part no. for 3 bar MAP sensor, they are modified 2 bar sensors.

AS the newest member of the Meth group/and installed myself. THERE IS NEW REVISE. PARTS in the kit. Haven't had the time to do a thread on different, But ONE the 3bar sensor come in a ford parts box with same part # of the MAF sensor (the one before throttle-body). And 2weeks ago Andy(LMS) gave me the 3bar 170deg NO METH (XV1) tune. As part of the three 3bar tune, +stock tune (4 total). I'll get the 3bar P/N later.

What you find is the part no. Is for 2 bar MAP sensor on you 3 bar MAP sensor box. It's not a off the shelf part as stated before, these are modified parts.
Shoman I don't why you see the need to trump my info all the time, LMS is 3mi's from my home I know Dan Milen well enough to have direct contact with him. So I consider myself to have a little more knowledge then most, not making this a brag. It's just simple semantics, as always I try to keep my conversations friendly and factual. And I let people believe what that want believe. So let's just leave at that my friend. No good will done here by me by proving your misinformed.

Maybe Livernois modifies the 2 bar to work as a 3 bar, but I bought mine directly from Torrie.

As I recall, I was using a 3 bar sensor first, and Darreli got his from Torrie a month or 2 later than I did. The part # on mine is:

Line 1 FoMoCo
Line 2 AA5A-9F479-AB
Line 3 G1UHF  Germany
Line 4 5WK9 6848

I have it sitting next to me as I write.

The part # for the 2 bar sensor that came from the factory is:

Line 1  Ford
Line 2 2R3A-9F479-AA
Line 3 8K22

I also have this sitting next to me as I accidentally slammed it with my hood and broke the cage. I had to replace.  Cost roughly the same as a 3 bar sensor.

[crash712us]

Not a expert on part no's. But from how they where explain to me, by a ford engineer. The part number you have there are the same, there is a prefix which could manufacture- part no. - and AA is 1st run the AB is a 2nd run.
This subject has been touch upon before on the other forum. I still have the box my 3 bar came in and part no. Is identical to the 2 bar.
And oddly enough I smashed my 2 by closing the hood also.

My Installed 2 Bar Sensor #'s are as follows:

Line 1  FoMoCo
Line 2 AA5A-9F479-CA
Line 3 G1UHF  Germany
Line 4  5WK9 6847

Note the difference on line 4.   Both of the FoMoCo German sensors came from Torrie.  He may have gotten them for Ford GT's, which he does a big parts business with.

The 2 bar sensor had a blue 0-ring and 3 bar has a red-orange O-ring.

On the sensor in front of the TB, the numbers on all 4 lines are exactly the same as my 3 bar sensor.

I'm so confused...

[EcoBrick Bob]

The simplest solution is to order one from Torrie & Fast Parts Network  (Torrie & Unleashed Tuning)

Mine shipped today from Torrie
