hi for some reason it seems that finding the right sensors is a problem
does any body have the correct OEM part numbers for these two different sensors i have seen after market part numbers and names all over the map one will call it a map and yes i do know what map stands for and the other will call it a baro but it would seem no body calls it a turbo boost sensor and baro.
the shop put a baro in place of my boost sensor so the truck has no boost
the numbers would help me out so much if you would like done right do it
your self

MAP is manifold absolute pressure. This on is on to of the intake, looks like flat rectangular.

BARO is in the firewall.

Turbo boost sensor in on the driver side of manifold, have a green dot or some sort of dot. The vacuum line can be traced from the vacuum and to the turbo. The other end have an electrical connector.

There is a Part sticky on top of this section for most of the common part no.

Here is one from my notes:
Wastegate Solenoid (Turbocharger Boost Solenoid) GM:1997227 Delco:214-1073

Sorry for the misunderstanding.

I am not aware of turbo boost sensor, that is something that most people install as part of the turbo boost gauge.
Or the ECM gets it from the MAP sensor.

Probably somebody can chime in.

As for the other sensor, another place to check is RockAuto.com
I have not had to replace those, it is usually not a problematic part.
I know only a few people needs those.

ok on my 1994 F VIN on the fire wall driver side there is a baro sensor
on top of air intake from turbo charger there is a turbo boost sensor
looks just like the baro sensor but it's not the calibration is different
than the baro GM calls it boost pressure sensor 2 bar 200 kpa
29 psi ok is this a test or something

I always thought map & boost pressure sensor were synonomous as regards terminology on a Diesel.A map will read both vacuum & positive pressure ,but called sometimes a boost pressure sensor on a Diesel since there is no vacuum involved only pressure hopefully. Stand to be corrected.
Sorry, cant help with part numbers ,would suggest using both map & boost to id the sensor & tell parts guy you dont want the baro..

The sensor on top of the intake that "looks" like a MAP sensor is not(well kind of it may be called that "technically"),nor is it a Baro sensor, on this engine configuration it's your boost sensor,gives the PCM it's info on the boost(PSI/pressure) levels the turbo is producing at any given moment,there is no "traditional" MAP at least not on this engine(f)'95 up,or any turbo 6.5 i believe.

it should have a light green/black/gray wire harness/plug


anyway yea i know your looking for a p/n so just contact your GM dealer they should be able to tell you the part number.

or try this number....

GM MAP(BOOST)sensor....

ACDELCO Part # 2131545 OR GM#12569240, 16137039, 16254719, 213356.

THANKS Daman1 for the reply yes your right here is some more info to be clear on the Gm discription for these sensors is boost sensor 10-200 KPA 0-5 VOLT true boost is measured by subtracting baro from boost and baro is 10-105 KPA 0-5 VOLTS and yes one is mounted on the intake and the other is on the
firewall there are three sensors out there sail as auto part stores would name
them one is a 1 bar map two is a 2 a bar map three is 3 bar map this is the
common name used when advertized by places selling them go figure
also the connectors are keyed different. i did a little bit of research
and come up with the proper OEM part numbers then i found them on this
forum in the parts list DU! the truck is fixed now thanks for everybodys
help oh by the way the gm house is the one who put the baro on
my intake so go figure and yes they broke the connector to do it
