Check engine light came on today. Auto Zone does free OBD-II scans and showed a code P-1132:
P1132 HO2S 11 Indicates Rich
Anybody know if I can trouble shoot the O2 sensors with a DMM (digital Multi Meter)? There are two - one fore of the CAT and one aft. They are pretty expensive to just replace them because they show a fault. One is $125 and one was $160something.
I don't have a Chilton's or Haynes manual and will do some looking online tonight to see if I can find some info on troubleshooting the Oxygen sensor.
Thanks
