Re: Add to the Volvo 850 Trouble Codes page
I think there are some discrepancies between this list and the factory service manual that could create some confusion. I found some in A2.
From the webpage:
From the webpage:
From the factory service manual:414 Boost pressure reduction from TCM

Re: Add to the Volvo 850 Trouble Codes page
Some codes that are not on the front page yet:
Socket A-2 (fuel system)
511: Long term fuel trim lower limit at idling
512: Short term fuel trim lower limit
I actually got 512 right now and am not sure what to do about it. Someone somewhere mentioned this (possibly from the service manual?):
If the short–term fuel trim remains lean for more than 3 minutes and engine temperature exceeds 75°C (167°F), DTC 5–1–2 is set.
Not sure what would be the most likely cause. Aging fuel pump? Clogged fuel lines? Some sensor gone bad?
