Acute onset O2 sensor(s) failure; x4; hmmmm??
The other day my well cared for 2005 S4 avant with 86k miles lit up my MIL light. I simply started it up to idle for 15 minutes, and warm up before going home from work (I live in Alaska).
Invested in a Ross-Tech VCDS and it provided the following information with an Auto-Scan:
____________
4 Faults Found:
16440 - Oxygen (Lambda) Sensor B2 S2: Heating Circuit
P0056 - 004 - Malfunction / Open Circuit - MIL ON
17548 - Oxygen (Lambda) Sensor; B2 S2
P1140 - 004 - Internal Resistance too High - MIL ON
16420 - Oxygen (Lambda) Sensor B1 S2: Heating Circuit
P0036 - 004 - Malfunction / Open Circuit - MIL ON
17522 - Oxygen (Lambda) Sensor; B1 S2
P1114 - 004 - Internal Resistance too High - MIL ON
Readiness: 0010 1101
Mode 07: Pending emission related fault codes
Address 10 (Engine): 4 Faults Found:
P0056 - Oxygen (Lambda) Sensor B2 S2: Heating Circuit: Malfunction / Open Circuit
P0161 - Oxygen (Lambda) Sensor B2 S2; Heating Circuit: Malfunction
P0036 - Oxygen (Lambda) Sensor B1 S2: Heating Circuit: Malfunction / Open Circuit
P0141 - Oxygen (Lambda) Sensor B1 S2; Heating Circuit: Malfunction
_____________
Obviously it provided more information than provided, but this seemed to be applicable. It does not make sense that multiple O2 sensors would fail all at this same time. I checked fuses in driver door, and all looks good. Any ideas crew? Any and all help would be appreciated.
