Hello DA,
I got a check engine light on my 07 EX-L V6,with code P0154.



I have done some Googling, and I found some threads referring to it as the front-top O2 sensor.
Can anyone confirm? And is it number 10 on this chart?




Thanks in advance,
AA

P. S. Sorry for the mess. My first time posting using mobile.

p0154 refers to bank 2 sensor 1. Bank 2 is closest to the radiator. and sensor 1 is closest to the cylinder head.

Make sure to check the obvious, the sensor is plugged in and no small creatures have been snacking on the wires.

Great, Thanks a ton.

unplugged, cleaned, and re-plugged it. No improvements unfortunately. Thanks for the advice.

in my experience with honda 99/100 O2 sensor codes is due to a faulty sensor. Replace it, clear the code and call it a day.

That AF/O2 sensor is a pricy one, but go with the Honda part as the aftermarket ones never seem to last as long or work correctly.

100% correct. Very often aftermarket parts end up costing u more money than biting the bullet and spending the money on Honda parts. Honda's engine monitoring systems (i can't think of a better word for it) have VERY small tolerances. Things like cats, data sensors, valves and solenoids are better off with OEM. In this business u get what u pay for. Almost everytime. Good call greg1c

Thanks guys for the advice. I will check if it is sold around here for less than a pound of gold, or I will have to order it from the States.
