would the hose on the valve cover (that hose on the valve cover that goes into the intake pipe)
the cause of the ecu code 'cuz it was disconnected for a little while while engine was running?


Yes....this could set a secondary air code. Reconnect the pipe, reset the ECU, and drive the car awhile.

connectors are the first thing to check for any code. In this case, check the connector to the electric pump which (I think) is located in front of the driver's side wheel underneath the bumper. Can someone check me on location. Clean the connector and make sure it is tight.

Im also tryign to get rid of this problem too. anyone have a picture of how that is suppose to be connected? Just wanting to make sure I have that right before I spring for another pump and relay

I will need to check and see what code I had, but I was throwing a code for that air pump under the bumper too. The lines going to it were swapped around on accident. But if you just had a code pop up, maybe it's something else.

BTW: Honda charges $975 parts and labor to replace that air pump.
