I am throwing a code 20 and 41 , 20 = Electrical Load Detector, i dont know what that means.... 41 Is an O2 Sensor, i know i have that problem, so what i am asking is what the hell is an electrical load detector and why is it throwing that, could the os sensor have anything to do with it?

 

hmm, I never had that problem when I did my b18b1 swap into my 97 ex. I rewired my civic harness to fit 0bd1. I was afraid of getting the ELD code. But the ELD code is something to do with under the fuse box (I'm not sure though), I read about it on my haynes manual. The only codes I'm throwing is my IAT sensor and my 02 sensor. I have to replace both sensors cause they were bad.

 

Electrical Load Detector tells the ECU when to start and stop charging the alternator and regulates the power to the alternator to charge up the battery.

It may be defective but it's located in the dash near the fuse box or not hooked up.

As for the O2 sensor, verify it's wired properly if you had a 1 wire o2 sensor.

What motor and what car?

Just a lil tid-bit to add to that.... the ELD is only on the US ECUs, so if you had a JDM ECU, there would be no ELD to worry about.

thanks man ill check that

 

If you read the ELD voltage at the ECU, it should be ~2.5 - 3V with all acc's off. If you then turn the lights on, this voltage should go down and continue down with other acc's being turned on as well.

Basically the ECU supplies the ELD with +5V. The ELD acts a variable resistor with its resistance changing based on current flow.

 

Where exactly would the ELD be located at in a 1997 Civic Ex????
