I have a no vtec 1995 Honda Accord Lx 2.2L. The engine light is on and I changed the oxygen sensor in front by the exhast manifold. Does this car have a downstream o2 sensor? where can I buy?

 

Yes it does have a secondary O2, you can buy one anywhere O2 sensors are sold. Before you replace both O2 sensors, did you retrieve the codes that were stored on the ECU? If so what were the codes?

When the engine light is on (check engine light or CEL) that means there are codes stored on the ECU.

 

I have tried NAPA, rockauto and others. I found one a 96 prelude s and a 96 Odyssey LX but can a F22A1 sensor Fit my F22b2?

 

What engine light code do you have?

 

I don't have the code. I had the car check by Honda dealer.

 

Wait a minute, the 95 OBD1 Accord only had the 1 O2 sensor. It doesn't have a secondary. Sorry, I was thinking that it was OBD2.

Ok So they told you it was your O2 sensor?

If you have already replaced the O2 sensor did you reset the ECU? Disconnect the battery (-) ground connection for 30 seconds or pull the back up / radio fuse for 30 seconds and that will reset the ECU and clear the CEL code. If you have the factory installed stereo you will need to make sure you have the activation code before you disconnect the battery.
