This is where you can add your additions to the 850 Trouble Code table.

Simply post a reply to this thread with the code(s) you're addressing, and any notes or links you want me to add to the table.

In a few hours (hopefully) Voila! They'll be on it.

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:
414 Boost pressure reduction from TCM
416 Temperature warning level 1
432 P0331 Rear knock sensor signal
433 P0331 Front HO2S slow response
435 P0133 (slow), Front HO2S slow response
From the factory service manual:
414 Boost Pressure Regulation
416 Boost Pressure Reduction From TCM
425 (P0140) Temperature Warning Level No. 1
432 Temperature Warning Level No. 1
433 (P0331) Rear Knock Sensor Signal
435 (P0133) Front HO2S Slow Response

Stage 0 in progress...

Excellent find, thanks K. I'll figure out what to do with this.

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?
