Barometric Pressure Sensor swap

Hi
I ran the codes on my 84 TurboCoupe and the scanner is telling me I have a Barometric Pressure Sensor problem.
After internet searches, I've found that 85-86 Escorts, all EXP's and 89-95 T-Bird Super Coupes use the same BP sensor (Sensor # DY-530).
Does anyone know of any other Fords that use the same BP sensor ?
I'm hesitant to drop $100 on a new sensor to find out I diagnosed the problem incorrectly when I can just dig through the junkyard and pilfer a sensor from another Ford for a few bucks.
Any guidance anyone can give me will be appreciated and I will be more than happy to post my findings here for everyone's use in the future.
Thanks very much,
Dave

Personally I'd just pickup a used one first and see if that clears it up. That is the same sensor used for speed density and mass air from what I've found going EFI on my 69 Stang.

Just my opinion.

I want to get a used one from a junkyard. That's why I need to know if anybody knows what other Fords the same BP sensor is used on. Finding turbocoupes in junkyards is near impossible.

This forums is for listing the info.

What code # did you get? Have you checked the connector and wiring. They do fail but not real often.

What does, "This forums is for listing the info" mean ?
I received a "22" on my Sunpro computer code reader. According to my manual, "22" is the "Manifold Absolute Pressure sensor or Barometric Pressure sesnor -signal voltage out of specification (engine off) or not at normal vacuum levels (engine running)."
I removed the connector at the BP and cleaned the connections but when I scanned the computer again I still received a "22".
The wires do not look bad.

Maybe this will help.

If it walks like a duck, quacks like a duck, and looks like a duck, it is a duck...... Any sensor you find on any Ford that looks like your current sensor is electrically the same as your sensor, and will work fine. The only difference between a MAP and BARO sensor is the BARO has a little plastic nub on the bung to remind you not to hook it to engine vacuum.

Cars to find them on: Any 5.0 Tbird, Crown Vic, Early Taurus, Early 2.3 Stang, 5.0 Truck,etc. Basically any Ford that isnt a mass air car.

Yes, that does help very much - Thank you !
I will search the junkyard tomorrow for a BP sensor and go from there. I looked on 2.3l mustangs before but I didn't see any BP sensors on them. I checked the pass. side strut towers. Are they located someplace else on these cars ? Are they usually located on the pass side strut towers on the other Fords ?
Additionally, what is a "Mass air car" ?

Like Pete said it is a pretty common sensor so you should be able to find something out there with one on it. My old 87 F150 50 has one on it as a reference and it's a speed density setup.

From what I understand (which is likely very little):

Mass Air setups use a Mass Air Sensor that works similar to the variable air sensor in the TC cars but uses a heated element (instead of a vane) to sense how much air is going into the engine to allow air/fuel adjustments along with other sensors such as O2 sensor.

A Speed Density EFI setup is basically pre-configured for the engine size and setup and the computer really doesn't know how much actual air is entering the engine. Is uses the MAP sensor (Manifold Absolute Pressure) sensor to adjust fuel/air based on engine vacuum and O2 readings, etc. Speed density setups usually do not respond well to engine changes such as cams, etc since the computer doesn't know about such changes. Unless it is a tunable setup like Megasquirt, etc where you tune it yourself.

A variable air or mass air computer uses the surrounding barometric pressure to fine tune it's controls.

I'm sure someone can/will correct me where I'm not quite right but that is a long answer to a short question based on what I know.

Well, you guys sure know your stuff.
These BP sensors are everywhere ! However, every sensor I found had a different part # on it and every one of them had a vacuum line hooked to it that appeared to go to the intake. The sensors look the same and have the same colored wires but I know that our T-birds don't use a vacuum line. Will these other Ford car sensors work properly on a turbocoupe without a vacuum line on them ?
Additionally, should I just plug the new sensor in and fire the car up or should I pull the cable off the battery or clear the codes on the computer or do something else before installation ?
Thanks again for everybody's indepth knowledge. You guys rock.

Dave

Should work. If the vacuum line is hooked up it is used as a MAP sensor on a speed density computer, otherwise it is used as a BAP sensor on a mass air or vane air computer like the TC's.

Personally I would reset the computer and then give it a try.
