Hi, My 1998 S70 with 120,000 miles (2.4 litre-5 cyl.) is getting an engine fault code P0172. I tried the seach feature on this site and keep getting an error message. Does anyone know what this may indicate and what I might check.
Also are any special tools needed to change a front wheel hub-one bearing is getting noisy.
Thanks for the help

Ed

    I got the 172 code also on my '97 850. Turns out it was the lousy air pump that was flooded (water accumulates in the pump). Replaced the pump and check valve - pump located below the battery on a '97, but they moved it on later models. Same thing happened, same code reappeared. So I drilled a 1/8" hole in the bottom of the air pump, the water drained, and presto - no code for the past few years.

    For grins I did an autopsy on the old pump - massive rust caused the rotor to bind and the electric motor to freeze up.

    Pulled my hair out figuring out this one.

    Good luck

    Flinch

    System Too Rich (Bank 1)

    Use this link to get Pnnnn codes: http://www.actron.com/code_lookup.php

    Remember the codes are for V8s, so you will never have Bank 2 :)


    You probably have a vacuum leak somewhere around your intake manifold.
