2005 Accord Coupe 4cyl 5 speed automatic EX. PZEV

I am trying to get information on the O2 sensors for my car. Auto Zone scanned my trouble code and told me the sensor needed was the pre cat. The one under the exhaust manifold. The one I got looks just like the one that fits in the cat and goes throught the floor pan and connects under the passenger seat. It is about 3 feet long, Bosch Part number 13704. I can only find two sensors and after talking to Napa and Auto Zone they say their is 3 different sensors. Pre cat, post cat and one other i can't remeber.

Autozone is correct, for the v6. There are only 2 oxygen sensors for our car, the primary one located directly before the cat in the exhaust manifold (haven't ever seen it on a stock car so all I know is on a modified one). The other one, the secondary is located either in the cat or directly after it. Regardless, there is only 2, not 3. As far as the part #, can't help you there, but I'm sure someone else can.

BTW, what was the DTC code? That can tell you if it was secondary or primary, making life a lot easier.

Good luck!

The pre-cat sensor is #16, probably reach it from underneath the car.


The other sensor is #32, located IN the cat. There is no 3rd sensor. The one shown as #17 is for other Accords that share the same parts drawing. Your car should have a rubber plug in the floor pan, or maybe doesn't even have a hole for #17. My 2003 Accord has #17 rather than #32.
