tried everything still getting CEL....

Z4-VILLA · 04-11-2012, 05:44 PM

just finished installing a new e.g. t . sensor and after clearing the code I'm still getting code 2c9c for the get sensor. I have my o2 sensors and get sensors relocated but wtf? my the bungs were welded up incorrectly .... I also have the ess tune but the damn light is still there. ESS never answers or calls me back so I have no idea how to move forward here.

Just posted a thread with the same issue in general forum. I did not relocate rear O2s, but have EGT in same location as stock headers, with Epic tune.

wss4 · 04-11-2012, 06:23 PM

However, looking at the document I have with codes listed, 2C9C is a pre-cat O2 heater input signal bank 1 code.

Very likely u have things wired backwards or incorrectly. That was my issue a while ago..

Did u always have this issue?

Z4-VILLA · 04-11-2012, 06:46 PM

I've been gavin this issue ever since it got cold.... in the summer it was fine. I don't know if this is in anyway related. Also I am using a re-welded stock section 1 so maybe the positioning is less than tolerable. Im frustrated.

Same problem here. I had ESS flash it twice. I think maybe I could have damaged a o2 sensor when installing. Totaled car since and haven't got new headers for the coupe. Good luck.

I just talked to Roman at Ess Im gonna get in touch with AJ and see if they can turn off whatever is causing code 2C9C (lambda Sensor heater pre cat 1)

sabbanick · 04-11-2012, 09:11 PM

Or it could be that you lambda sensor is shot!

Z4-VILLA · 04-11-2012, 10:40 PM

lambda? as in o2 sensor?

gcochard · 04-11-2012, 11:09 PM

Yep lambda = o2

Z4-VILLA · 04-17-2012, 09:28 PM
