Hi:

I have a 2003 Honda Civic Hybrid w/ the P1166 & P0134 codes going off. The solution to fix seems to be replacing the upstream O2 sensor. Is the best part a Honda O2 sensor or does Bosch,..., work just as well???

Thanks!

 

Go with factory on this. I brought in an o2(air/fuel) sensor I bought from autozone and the shop owner that does hybrids whinced and said he would install it, but he would highly recommend getting the factory o2 sensor.

When I go with oem parts I go to http://hondaautomotiveparts.com as they have the best prices and you could save a good amount of money.

Apparantly our cars are sensitive to this particular component. Lots of people have experienced issues with aftermarket o2 sensors. If you do want to risk an aftermarket sensor go with Denso. But If it were me. And it was. I'd go with the factory o2 from Honda even though it was $100 more expensive.

 

I solved the sensor problem; success!

New BIGGER Problem now.

Both the P1600 & P1449 are showing w/ check engine light & IMA lights. What worse is the IMA stopped regenerateing and assisting for a day then suddenly started working again.

Is my IMA or something else going bad???

Please advise: HELP!
