Apologies in advance if this is posted in the wrong section.

I just bought a 1984 HO z28. It came as an unfinished project with a newish motor from a 1984 l69 trans am stabbed in and running but far from complete with loose ends all over.

I have been slowly working through vacuum lines and adding/replacing sensors to get the trouble codes to disappear.

Currently I am showing a code 34 that I am assuming is due to a missing sensor that I cannot find. I think it's either a map or a barometric pressure sensor.

I have attached 2 pictures. Can anyone tell me what this sensor is? There is no vacuum line attached. I just pulled the plug for identification only. This sensor is located between the D.S. fender and brake booster.


Second pic. I need to know what attaches to this plug if anything. The wire for this is currently coming out of the harness right under the distributor.
Please ignore the hello kitty band aid. I filleted the end of my thumb and had to keep it clean.

First one is for the MAP sensor. Should be a small hard plastic vac line coming out of that harness, or otherwise near there, as well.

2nd one is baro sensor. Ordinarily mounts to the edge of the windshield cowl about right above the heater hose nipples.

If the hard plastic line for the VAC sensor cannot be found it can be replaced. It runs to the rear port on the carburetor.

Thank you gentlemen. New barometric sensor on the way.
