Broke down south of Macon, GA (Subaru engine)

[space]

2.5 subie was running hotter than normal 205° Degrees.

I have a O2 sensor heater code p0037
Baro pressure sensor p2227
Ho2 heater p0030

As soon as it hit 205° it lost power and stalled.

Any ideas to on the problem, or a mechanic in the area?

The slightly high temp is probably a red herring. If your gauge is accurate, 205F is a safe temperature, well below boiling. Are you saying the engine won’t restart after it’s cooled down? Will it turn over? Did you loose any coolant? Is your expansion tank full? Does the fuel pump cycle when you first turn the key?

the o2 heater codes don't normally cause a driveability issue UNLESS they are internally shorted, then you have problems. i have seen on VAG products a bad o2 wipe out the ECM

the baro code can cause all sorts of issues as it helps with fueling. it could be pig rich or dead lean.

205* isn't hot...usually but this time of year it would seem not to be normal as many (stock) subarus tend to run in the 190-195* area.

i'd try and disconnect the baro sensor and see what happens. it should shove the ECU into limp mode and while performance may be reduced it should still run.

but, if the o2 codes are there and in fact shorted internally it may do some pretty crazy things. typically they will code for the heating circuit being burnt out but like i said if they shorted to the signal side of the sensor you'll need to do some diag for sure

UPDATE:
It seems all sorts of weird things going on

1 replaced the map sensor (cleared code)
2 o2 htr trouble code still present 0037
3 vss code tripped (replaced sensor cleared code)
4 LTFT is -10ish (vac leak?)
5 STFT is +.08ish
Seeing as I havent driven it in awhile how long does it take for the LTFT to establish a base?

Problem is the van is driving very sluggish
What next?
Change out the o2 sensor?

Was running perfect before the breakdown
Seems strange all these would go at once, unless related?
TIA

Have you made sure all the grounds and connections are clean and tight.

had you filled the gas tank recently? if so, suspect bad gas. depending upon the OBD system, it can throw all sorts of trouble codes seemingly unrelated.

your fuel trim is about right

LTFT is indicating you are pulling fuel (running rich) but how long was it running? if not up to temp and a good 30 min drive i would disregard that

if your o2 heater is dead or something is up in that circuit you need to fix that. the o2 heater comes on and off as you drive if the o2 is below temp it can and usually does run like shit

Skills is the baro pressure sensor on an 05 2.5 on the ecm or part of the MAP sensor?
Ive gotten conflicting opinions
Thnks
