How to fix ecu error codes 20 and 22?
I just put a h22a in a 94 accord. Its showing codes 20, electrical load detector, and 22, vtec pressure valve. I have no idea what these could be or where to start looking to fix the problems. If anyone knows or could help out I'd appreciate it a lot. Thanks.

The ELD is built into the underhood fuse box. Check the circuit to this, but if the ELD itself is bad you gotta buy a new fusebox.
The VTEC oil pressure switch is on the side of the VTEC spool valve. I think it usually has a green plastic plug on the wiring harness. That code can be caused by low oil pressure, it doesn't automatically mean the pressure switch is bad.

Alright thanks. But I checked the oil level and its full, and I also changed the pressure switch. I reset the ecu and it still shows the code. I cant figure out where else the problem could be. Any more suggestions would help, thanks.
