2001 S4...what do some of the terms in these codes mean?
 

16522 - Oxygen (Lambda) Sensor B1 S2: Signal too High
P0138 - 35-00 - -
17522 - Oxygen (Lambda) Sensor: B1 S2: Internal Resistance too High
P1114 - 35-10 - - - Intermittent
16514 - Oxygen (Lambda) Sensor B1 S1: Malfunction in Circuit
P0130 - 35-00 - -
17585 - Bank2: O2S (Lambda) Correction Behind Catalyst: Control Limit Reached
P1177 - 35-00 - -
17584 - Bank1: O2S (Lambda) Correction Behind Catalyst: Control Limit Reached
P1176 - 35-00 - -


specifically the last 2 codes...what is the ECU doing as a result of these problems...reducing boost, timing, etc? the first 3 codes suggest a bad 02 sensor right?

you're correct - the first three can indicate a faulty o2 sensor
 

you'll need to take a look at the sensors, and test them if possible, I would examine group 033 for testing to see if the values are within spec - if not, you probably need to replace the o2 sensor, or take a look at the wires to see if there is an opening in the circuit.

As for the last two, it sounds like you need to check all your o2 sensors, both before and after the catalytic converter. What happened to make these codes come up, do you have any idea? The ECU will most likely pull both boost and timing, to reduce possible damage to the cat. I would see if I could diag these ASAP - do you have access to a Bentley for obtaining the proper values?

Cheers,
Kenny

I do not have a bentley manual, and don't know how to test O2s...
 

what do I do? what valves are checked in 033? What values should I expect to see?

try this...
 

log block 043 and 044 at idle - look at field 4, it should indicate "B1-S2 OK" (or B2-S2)

log block 030 at idle - each field should indicate "1 1 1"

these would be the first places I look... if anything seems out of whack, I would also log blocks 033 and 032 at idle and post your results...

my IM is twotrbos1mission if you wanna IM me for some additional info... I'll try and help as much as I can. Good luck-

Kenny

kenny, thank you, I will do this tonight...I appreciate your help, I'd be lost without ya here!

no problem, just tryin to help out... let us know what happens!

Logs...
