14: Barometric Pressure Sensor
15: Exhaust Gas Oxygen Sensor - voltage stays below .55 volts (Lean)
17: Exhaust Gas Oxygen Sensor - voltage does not change (rich)
I got all these irght now. What does this sound like?
From a 95 Ford Escort GT.
It possible that your car as a barometric sensor, either built in with the MAP or seperate... so when you drive to higher/lower altitudes it can compensate for the thinner/thicker (read: more/less dense) air.
BUT... It could be as 2Tone said, that because your O2 is most likely faulty it would be causing u'r barometic sensor to go whacky...
I'm guessing u'r car is probably an OBD II car because it's a '95... and ODB II cars don't like it when sensors fail.
Replace the O2 and check the connection points and go from there.

If you look at the factory service manual in the diagnosis charts, it says "Faulty Barometric Pressure Sensor - Replace ECU". Haha stupid Mazda. I doubt that sensor is important anyway, its not like there is any significant elevation change in Ontario.
^ ahhaha that's funny. Awell. I've got another ECU in my garage anyway
but ****, all the 02 sensors for my car are 300-400 bucks! 288 from mazda, 300 from Napa, and 388 from Carquest. I found a universal one from carquest (i think) for 147 bucks... not sure what i'll get.
