S80 codes question

asummers · Post by **asummers** » 09 Feb 2010, 07:56

Has anyone had these codes on their S80, and know the fix for them?
P0154 02s ckt no activity detected 2/1
P0174 system too lean bank 2 (i figure this one is for the o2 sensor)
Question - Basically which set of 02 sensors is this referring to?

I also have these codes, but it is from my transmission needing to be rebuilt...
P0756 shift sol B ckt perf stuck off
P1181 man. specific dtc (i figure this one is for the trans ?)
P1618 man. specific dtc (i figure this one is for the trans ?)

If you go here you can plug the codes in for definitions: http://www.equus.com/

I think bank 2 is the passenger's side.
