I posted earlier about an automatic 96 outback with the CEL light on. A friend of mine grabbed the (only) code from the computer and it yielded PO 106 or in layman's terms: Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem.

 

After clearing the code so far it stays off but is this something to be concerned about if it comes back on again? What does the result mean?

 

 

Thanks for your input,

I figured this one out...I realized that the vacuum hose from the MAP (?) was disconnected to wherever it was connected. I am guessing that this is what was causing the PO106 code.

That's a very reasonable guess.

 

The computer uses the MAP sensor to calculate how much air is entering the engine so it can make educated guesses about how much fuel to inject. The sensor is mounted to the firewall, near the passenger side fender. If its hose was disconnected or leaking, and you fixed it, the code should stay off and you should have nothing to worry about.
