THIS HAS BEEN DRIVING ME CRAZY SOMONE PLEZE HELP IDK WHAT THE PROB.IS I KEEP GETTIN A CHECK ENGINE ON MY STOCK 0BD 0 D-16 BLOCK 91 CIVIC THE ECU FLASHES ONCE I THOUGHT IT WAS A HEATED O2 PROB. SO I REPLACED IT BUT ITS STILL DOING IT SOMONE PLEZE FILL ME IN ON ANYTHING YOU THINK IT MIGHT BE THNX

 

well take off the caps to start...and is code 1 the only code it throws???have you tried routing the wire from ecu to o2 sensor b itself on a seperate wire???

 

yeah ive tried it all even as far as replacin the ecu as an alternetive and nothing? idk what else it could be.

 

are you sure its code 1 and not code 10, is it a fast flash ofr a slow one?

 

yeah its a fast one and i thought it might be code ten but its not i even replaced the intake air temo. sensor.........

 

Im having same problems. Check engine light on. Throws a quick flash and nothing else. Cranks but aint going anywhere. Was thinking its a Ignition Coil since i changed dizzy cap, rotor, wires and spark plugs.

 

Also replaced O2 sensor and nothing
