thats what i thought it was the air temp thing. i changed it with a new one and the check engine light still comes on and the ecu still flashes one long one so what the heck

 

have you tried to see if the circuit is at fault???

 

how can you tell if the circuit is at fault

 

what ECU do you have? - OBD0 D-series ECUs don't have long and short flashes, only short

 

i dont know its a stock 90 civic dx hatch d15 from a crx. is there a difference between a d15 hatch and crx?

 

stock ECU flashing once is O2 sensor

 

i replaced that to but i will check that out later thanks

 

can you scan page 11-36
