Did you remove the backup fuse to clear any codes?

I dunno.....worse case I would bypass the car harness and run the signal wire straight to the ecu.

what are you calling the back up fuse? the one in the underhood fuse box for the ecu?

There should be a ~7.5 amp fuse in the underhood fuse box. I believe it stores codes as well as keep constant power on the radio.

It is right next to the ecu fuse in both 5th and 6th generation civics. If you do clear that code and it still comes up...something is still triggering it obviously.

ive pulled that fuse to reset it yes. but that code keeps coming back on. i guess i may have to try running my own wires and see what happens
