Hey guys,

I have the P1166, P1167 engine light problem on my 2002 CRV.
I replaced it with genuine DENSO 234-9005 sensor and I still get the same error.
If I clear the error with my OBD reader, all I have to do is turn the engine on and it comes up after about 10 seconds.
Is it supposed to detect the error that quickly from the sensor or is this something else with the wiring/fuse???
Thanks for any help. BTW, this is the second sensor I tried from a different dealer.

OK, solved!!!!!
LAF fuse. In the driver's side fuse box.
Blown out. Also gives P1166,P1167 error. GOOD TO KNOW!

Thanks! This one was driving me nuts! I kind of knew that the error came up so quickly that it might be electrical. But at the same time, I never saw any reference to that LAF fuse until I searched yesterday and found one post that mentioned it. I have the entire ECU/Fuse box replaced. I assumed the mechanic would have checked the fuses. Again I was wrong.
I'm just hoping others will save time with this post. It looks weird to see the dash so clean with no CEL or (for a while) SRS light (due to faulty seat belt problem).
