Hi there, i've been surfing this forum for a while now and thought that someone here might be able to help me.

I drive a 1989 Civic Si. I keep getting 2 error codes thrown by my ECU. I get a code 1 which is the 02 reading and a code 20 which is the ELD. Does anyone have any experience fixing these problems?

*I have replaced my 02 sensor 2 times and checked the wiring from the sensor to the ECU and there is a good connection.

Thanks for any help.

 

After you replaced the O2, did you reset the ecu?

 

I reset the ECU both times i replaced the 02 sensor. I got the same result each time.

 

It should be easy to fix the o2 sensor code. Just check if its in right and if the wire is cut. Also check the wiring to your ecu.
