I have two error codes. One is P0172 and the other is 2-4-5. Any ideas or help? Thanks

 

What system are they for?

 

What system? Not sure what you mean. It's a 95 850 turbo. Scanner said P0172 and then 245. Garage made some calls, but wasn't able to get any answers from anyone. He thought the 0172 could be an O2 sensor.

 

I wanted to make sure it was an engine code and not a trans or ABS code.

 

FAST850R> mY 98 s70 is giving me the same error code of PO172. I've yet to fix it but every body seem to think it is the Evap valve. You Might check out my post under Forum S70 titled Po172. My car is running great and getting great gas mileage right now is the reason I'm not in a hurry to get the check engine light out.
