dc2r Error code

[crx91sir]

Hi guys.

My dc2r running a Hondata S300 and its show on my laptop error code 41. I just want to ask how can i know which O2 sensor in my Dc2r as the check engine warning light came on? Primary heated o2 sensor or secondary heated o2 sensor? Which one should I replace?

Any help would be appreciated.

Cheers!

Dc2r doesnt have a secondary o2 sensor

If you look under the parameters window in the s300 software, you can disable the o2 heater and just run open loop.



A lot of tuners run in open loop, because closed loop tends to cause problems with AFR's

I had the same error code with my Dc2r as well. I replaced the O2 sensor and the check engine light is still on and I can't remove it via the Hondata software on my laptop. Do you think if I ran the above process you have mentioned it might clear the error code and the warning light?

Cheers,

You can try, but it should

dont run open loop for daily drive.
if engine light still comes on after o2 replacement, you check wiring continuity from sensor plug to ecu.

if wiring all good, go to an electrician or mechanic ey
