Hey all ...

My CEL came on and when I scanned the codes I got the following;

Address 01: Engine
Part No: 4B0 907 551 K
Component: 2.7l V6/5VT G 0005
Coding: 06612
Shop #: WSC 02325

3 Faults Found:
17521 - Oxygen (Lambda) Sensor; B1 S1: Internal Resistance too High
P1113 - 35-00 - -
17965 - Charge Pressure Control: Positive Deviation
P1557 - 35-10 - - - Intermittent
17539 - Oxygen (Lambda) Sensor; B2 S1: Internal Resistance too High
P1131 - 35-10 - - - Intermittent
Readiness: 0010 0001

Anyone got any tips as to what could be causing these? I cleared them to see what would happen and the light came back on shortly after clearing them and I got the same three codes. Car seems to be running fine and I actually seem to be getting better gas mileage lately LOL ... so I am a little stuck as to what the issue might be. So any help would be appreciated.

Thanks,

P1113 and P1131 are heated oxygen sensor warnings.

Since you're getting both banks at the same time, maybe there's just one heater for both O2 sensors? If that's the case it is probably the heater.

I can't find a P1557 for either 2.7T engine codes. The only P15XX codes are for the 4.2's. P1545 through P1565 deal with throttle control.
