Check engine light codes
hey everybody. i have a 2001 s40 1.9T with a check engine light that just came on this past weekend. took it to a local mechanic and he told me that i have two codes. they are listed below:
po236 - turbo pressure solenoid
po171 - system lean
was wondering if anyone could tell me exactly what these codes mean, what needs to be done, and how soon it needs to be done.
