Hi everyone. I have a 2006 Honda Accord V6 AT from NYC. This weekend the check engine light came on. It's reading a "P0134" code with the AutoZone scanner tool. Can someone please tell me which sensor this is and maybe send me a diagram if possible? Also, if this easy to change or should I take it to the shop/dealer?

Thank you everyone..

 

it's your bank 1, sensor 1 A/F ratio sensor heater circuit, (wide band oxygen sensor) bank one is the rear bank of the engine (closest to firewall)

 

Thank you. Is this hard to replace? If you or anyone else has a diagram please send.. I really would like to change this myself if I can.

 

On the exhaust manifold back against the firewall, #9 is the sensor you want. Not sure, but it might be tucked back under the ventilation cowling??

Unplug the wire for that sensor & find the 2 same-color (black?) wires from the sensor. Measure resistance between those wires. Not sure what it's supposed to be, but a failed heater normally shows open-circuit.

If that heater element is OK then you're looking for problems in that circuit like maybe blown fuse or cut wire.

 

Thank you! I'll try to access this on the weekend.
