I have 2002 euro civic type-r and I have K-Pro with new Honda PRB ECU based off US RSX-S
my cel is always on it's error code 41
I disable the o2 sensor heater but the cel is on again in a few minutes
does anybody have PRA & PRB ecu o2 sensor wiring??
euro civic type-r error code 41
We have the exact same problem here with one car (2003 CTR, PRB K-PRO ECU and RSX-S wideband oxygen sensor). This occured after a few months after a succesful installation. The error code:
Code: 41-1
DTC: P1166
Description: Heated Oxygen Sensor1 (Primary HO2S) Heater Circuit Malfunction
We have tested the oxygen sensor and the ECU on a another car and they're ok. The other car has a same setup is working properly. So the problem should be in the wiring. The modifications are made correctly but there seems to be a problem somewhere...
Let us know if you work out what's the problem. If we find out sooner, we'll let you know

Ok, we still haven't figured this one out. There seems to be a few people with the same problem even driving RSX-S. Hondata should really do something with this... For example this case:

The examples you posted were not the same problem you are having (PRB ECU in a Euro CTR) but were the result of wiring pulled out of the o2 sensor connector (common when using a race header) and plugged back in incorrectly.
If someone can provide a wiring diagram which works, we will post it here. Otherwise, this is a modification to your vehicle which we cannot test and verify here. For that reason we have never promoted swapping PRB ECUs into Euro CTRs.
