Help .........code 20 - Honda Prelude Forum

Hey guys ..... My car is throwing code 20 which indicates a problem with the electrical load detector. Does anyone know where this unit is located? Any info will be helpful.

I got this problem too, but it doesn't seem to restrict the engine.
I had the Si engine, then swapped it for the vtec, and this is one the problem started. I looked in the manual, and it seems that the load detector is sort of plugged in to the bottom of the fuse box in the engine compartment.
The 2.3 never had this, but i can see that it's there on a friends 2.2 vtec. I guess the load detector sensor in the 2.3 must be somewhere else, but i have no idea where.

Let me know if you find anything out.
What engine do you have by the why? Is it a vtec swap?

My car was origanally 2.3 si I then swapped in a 2.2 vtec. And I think its since then I be getting code 20.

The electrical load detector is directly under the fuse box in the engine compartment. It has a 3 pin connector with 1 black wire, 1 green w/ black strip wire(in the middle), and 1 black w/ yellow strip wire. Measure voltage between the Green w/ black strip wire and ground, their should be 5 volts if not you have a bad ELD

On my 92 2.3, there is NOTHING plugged in to the bottom of the fuse box, which is why I pressumed it must be located somewhere else in the 92 2.3. (Doesn't look like anything was there before the engine swap either)

Crazykid. Can you check the bottom of your engine fuse box, and tell me if you have the 3 pin connector plugged in.

I did get the info from a 95(4th gen) honda manual, did you remove the lower cover of the fuse box, on the bottom??? I guess it looks like the lower cover snaps off. I checked mine (originally a 93 s, now with a jdm h22a) and the cover under the fuse box does snap off, and the 3 pin connector is there, with the same color wires as indicated. let me know if you find it.

I'll check again, but last time I took the fuse box out, and there was nothing plugged into the bottom of it.
