EDU error codes for 89 Civic DX Hatch back
Anyone know how to interpret that blinking light on the ECU? I got a check
engine today and saw that the ecu light is flashing one time, pause, one time, pause, etc. It felt like the car missed (didn't fire for one cycle or something) and then came right back. That's when the check engine light came on. Thanks for ya'll help. |

Wherever it refers to a "code reader" they are talking about the jumpers they sell with this manual for $35 US or so. I bought the set before this was posted :-( Mike |

This will reset the Check Engine light. If the CEL does not illuminate again, forget about it. If it does, check all wiring for integrity. If good, replace oxygen sensor. -- TeGGeR® The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |
