Hello all,

I have a Honda CR-V(02). The malfunction light has been on. I asked someone at the local Auto Zone to check for me. He gave me two troubleshooting codes, which are p1166 and p1167. I have monitored my gas mileage and it seems fine. I have done some research and found that there is maybe some circuit problem, not with the oxygen sensor.


did anyone here experienced this problem?

thanks!

P1166 Primary HO2S (No. 1) Heater System Electrical
P1167 Primary HO2S (No. 1) Heater System

Not sure what your research turned up but the two codes you have ARE O2 sensor related. Both concern the "Primary" or upstream (ahead of the catalytic converter) F/A sensor.

If you decide to change it, please take a look around the forum (search) for more detailed information on suitable replacement parts.:)
