How to determine which O2 sensor is bad
The check engine light is on, I checked with a scanner and the code is listed below, it does not tell me which one of the two sensors is bad. How can I determine that, I would appreciate any help
Code: P1166 HO2S11 Heater Circuit Fault. Engine Info: 2000 Honda Accord EX 4 Cyl F23A4 Edit/Delete Message |

P1166 is the air/fuel ratio sensor, which is the primary sensor.
Here is also a link with a pdf for a few test for code P1166. http://www.driveaccord.net/forums/sh...d.php?p=229281 |
Re: How to determine which O2 sensor is bad
I concur. It is the primary O2 sensor. The clue is in the code, HO2S1. If it were a problem in the secondary sensor, you would have read HO2S2.

Thank you guys for the quick response. My OBD reader says that it has a problem with the heater but when I turn the ignition on the sensor heats up very quick

Can someone tell me where the air/fuel ratio sensor is on the 2008 civic si and why my dealer wants $583.00 to replace it?

here you go http://www.8thcivic.com/forums/do-yo...placement.html thats everything you need, literally part numbers a place to buy, also try BKhondaparts.com, and autopartswarehouse or even googling the denso part number all you need is one normal looking wrench, don't bother with those retarded O2 sockets, theres no room to use them on there anyways |
Re: How to determine which O2 sensor is bad
I just cut the wires, and use a regular socket(Youre going to replace it anyway). Install use a regular wrench, or a flare socket/wrench
