Hello Guys,
Thanks for great help, With the help of the members I am able to fix P1166 and P1167 error code on my 2002 CR-V. I replaced 02 sensor by Denso 234-9005 Oxygen Sensor (Air and Fuel Ratio Sensor). Got it from Amazon for $124. (Now on sale for $100).
This fixed the problem right away, CIL light went off by just turning the key to on position.
Drove for 2 days (about 100) miles. Engine light came on again....
I am getting error code P1456 "EVAP Emission Control System Leak Detected (Fuel Tank System)"
Any help ? I suspect, I might not have seal the sensor properly by anti-seized stuff or some other issue.
