Pulled some codes....

Pulled some codes....
I pulled some codes ( Ignition on engine off ) with my new scan tool, and I got a few questions. I got codes 10 11 33 & 91. 11 is crossing to a system ok code, and 33 is a EGR not opening properly code. Code 91 is showing up as a HEGO ( H02S ) sensor voltage low/ always lean, what does this mean? My Oxyogen sensors are bad? And what about code 10? It isnt even listed in my book as being a code. Thanks in advance!

RE: Pulled some codes....
Isure hope someone can answer that 91 code. I got the same thing. I have talked to a lot of people and no one knows what it means.
What scan tool did you get? What did it cost?

I got this one http://www.sjdiscounttools.com/epi3145.html it was $38 shipped, came with a code manual and all.

11 = System Pass(OD)
33 = EGR valve not opening(CM)
91 = No O2 Sensor Switching Detected. always lean -driver side(CM)
11 = No problems on the real-time check of the circuits when the test was run.
33 = You have an EGR delete courtesy of the EEC-IV since the valve is not opening when the ECM "tells it to".
91 = You could have a faulty driver side O2 sensor, exhaust leak, or a fuel control problem causing that bank to stay lean most of the time.....suggest to switch the O2 sensors from sides, clear codes, test drive the car for 5-10 min., and run a KOER self-test......if code 41 shows up instead of 91....the O2 sensor is fubar.

Yup that was the exact way the codes came out of my scanner, I was wondering why they where all repeating except code 10. So if it turns out its not the o2 ( for code 91 or 41 ) could the egr possible be causing a lean condition or would that be on both banks and not just the driver side? Could a faulty injector cause the same lean condition?

The EGR is "on vacation"...nothing to worry about, it will not affect A/F control or timing. A faulty injector will be in the company of a miss problem with a lean code most of the times.
