I'm posting this for a member Cam AKA Detaila - who belongs to my hondapitstop list and he recently did an H22A swap. Anyway, see below and tell us what you think about the problems he is having? Below is the text he sent me:
03/15/04 - Some wiring problems and error codes with the H22A
I figured out that when trying to connect egr lift selonoid valve sensor and fast idle thermo valve sensor to ecu we stuffed up the map sensor wiring, we fixed all that now the ecu doesnt throw codes for the MAP sensor.
Also, vtec is working again and the redline cut out must be at least 8000rpm cos i took it to 7800 when we drove around the block.
So, egr sensor is connected and so is knock sensor. but the ecu keeps throwing out the following codes:
20- Electrical Load Detector - defective circuit or unplugged / defective sensor
41- Primary Oxygen Sensor - Heater circuit malfunction
I'm going to swap the o2 sensor in my accord (which is the prelude one) for the accord one on my old A pipe and see what happens, if it still throws a code the problem must be in the wiring circuit-probably at the ecu.....hard to imagine because we hooked that up first as it was the easiest one, it goes in A6 on the wiring loom.
The other code the ecu reads out is the electrical load sensor which is nothing we have touched so I am wondering if anybody has any idea of where it is, what it does and why it would be giving an error code?
Anyway, I'm happy for now, I have my knock sensor and my iab so I can rev it up without detonation and the motor is getting its proper amount of air.
I still have to sort out where the egr and fast idle sensor wiring goes in the ecu?
