The codes that I got were these.

1.Heated oxygen sensor
2.Egr valve
3.Barometric pressure sensor
4.Ignition output sensor
5.Speed sensor. (that I have already replaced)

My question is, Can someone help find a diagram so that I can find these sensors on my car. I have tried google but found nothing. If anyone has pictures that would be great. Thanks for any help

 

Just from seeing the Baro sensor in your list I would lean towards you needing a new ECU. The baro sensor is mounted to the ECU so your not goign to be replacing that without replacing the ECU. If you have a friend with the same ECU try plugging that in and see if that clears up your codes.

 

Thanks for your response. I dont have anyone around me that has an accord. So i will have to buy one. One more thing The check engoine light does not come on untill about 5 or 10 miles. When the light comes on you can start hearing a knoock (that sounds like a rod) at 2200 rpm. in every gear. 2100 no knock.2300 no knock just at around 2200. I had the bearings replaced but it still does the same thing. Would the ecu some how be affecting that? Does the accord v-tec have a knock sensor. I got the car from a guy who blew the motor. I just put a used motor in. But he said before the swap everything was fine

What year & type engine did you replace the blown motor with? Seems like the wiring may be a bit off.

Do you know how the engine was running before you bought it?

Did you have the engine compression and/or leak down tested before you installed it?

 

The Ex / Vtec is equipped with a knock sensor. As a diagnostic tool; try running a few tankfuls of Premium Fuel with an additional can of octain boost and see if the knock subsides. Did you have the piston wrist pins checked for wear when you did the Rod/Main Bearings?

No i did not have the wrist pins checked. Sounds like that may be the problem. The motor checked out fine with a leak test.
