New to the obd1 from what i read and from what i understood 1 long flash is code 10 1 short flash is 1. its a eg gsr swap heres a link to video of the flashes


my understanding is this

Code 7 = TPS
Code 23 = Knock Sensor
Code 41 = o2 sensor (on header)
Code 45 = Fuel System too rich or lean

I don't know why its showing o2 sensor because i bought the subharness from rywhire and spliced it into the ecu , it came with Green , Red,Black, White Colors, From what i read Black and white are heater wires

Thanks in advance

 

What ecu, why not use your own harness from the eg? Why did you need to splce any wires when the ecu plugs, minus the secondary butterfly solenoid. I don't see a code 45.

 

p72 obd1 gsr ecu, and i think the eg harness was used , i "spiced" the wires to the ecu because there was already wires connected to the ecu pins that i needed to connect the o2 sensor so people from this forum said spice them into the wires

 

If you reset the ECU, do all those codes return?

 

Is this it? If so did you hook up the knock sensor? Check to make sure you didn't switch the TPS and MAP sensor connectors around. And recheck your 02 wiring but unless your car was a CX with a one wire 02 you shouldn't have had to wire up that portion. What is your year, make model?

 

So you're saying you ran your own o2 sensor? Don't splice that **** in, you need to replace it completely.

 

It's a 92 civic si with gsr engine and tranny, so if there's already some wires running to the ecu where I was suppose to plug the 4-wire o2 sensor take them out and plug in the O2 ?? Can someone tell me what the green white black and red O2 wires are

 

Do you have the service manual? If not, Google search it.
