O2 sensor location

It is a 2004 Honda EX. From your Pics I take it that it has two O2 sensors?

Where is the oxygen senser located on the car?

My catalytic converter keeps throwing an engine code p0132, 02 sensor 1 bank 1 high voltage, I have replaced the 02 sensor and the code keeps coming back. And quite often while driving I feel the car shutter and as I try to accelerate the rpm's start dropping and the engine starts losing power until I press the gas pedal all the way to the floor and the rpm's will jerk back up to where it is supposed to be and I have had it sputter out and die multiple times and stop light. When that happens I have to put the car in neutral and rev the engine to keep it from dying.

Check engine light is on. AutoZone read codes PO136 & PO137. Both codes are for oxygen sensor 2 in bank 1. PO136 says a malfunction exists in electrical circuit for the sensor. PO137 says input voltage from sensor is too low for current operating conditions. AutoZone says oxygen sensor 1 is closest to the cylinder head before the catalytic converter, while oxygen sensors 2 & 3 are located further downstream and are typically mounted in or after the catalytic converter. It also says bank 1 identifies the location of cylinder while bank 2 identifies the cylinders on the opposite bank.

Because car is driven so seldom, I'm not concerned about poor gas mileage. Car is running fine so fuel mixture must not be lean. Dealer quoted $220 to replace sensor and said engine isn't being damaged as long as fuel mixture isn't lean. I don't want to spend money to replace sensor. Will there be any problems?

I have a 96 honda civic dx(D16y7) 5 speed manual transmission. I recently installed a header in place of the manifold. After install, the car smokes after about 15 sec of run time. I noticed the old manifold had a cat connected to the manifold. This is where the sensor was located. Now the sensor is at the back of the header with the first cat removed. What could be the problems?

I replaced the front oxygen sensor. The rear sensor wires looks like they head into the car on the driver side. Where do I locate the plug from the old sensor?

Hello,

I have a 2004 honda civic ex 1.7L 4 cyc and I want to change the oxygen sensors and I understand that there are 3 oxygen sensors I know where the upstream and downstream are where is the 3rd one located help please?

Hi Joe,

I've located the ones from the bottom of the car but I can't find the 3rd one. I have a 2004 Honda Civic ex 1.7L 4 cylinder sedan I think it's a v tech.

Hi Joe,

I bought the car from a neighbor and it came without the manual. How would I know what engine my car has? Where can I buy the manual?
