P013c

[Virus]

I had my Solo catback installed 2 days ago. The shop couldn't get out one of the oem 02 sensors because it was bent and cross threaded from the factory. They had to order a ACDelco 02 sensor. I road around with it all day with no issues. I programmed my G8 with the Superchips Cortex Roto-Fab 93 tune yesterday afternoon. It previously had the 91 Roto-Fab tune. This morning on the way to work the check engine light came on with the above code. Any info or suggestions would be appreciated.

I am not even seeing a P013c listed. Are you sure its not a P013?

My Cortex said P013c

That doesnt sound like the correct code for a inoperative o2 sensor, should be something like a p04xx code...

But yes what happened is you completed enough drive cycles for the ecm to trigger a code, is this one of the front or rear o2's. If it is a front i would not suggest driving the vehicle around until it is replaced.

Looks like an O2 code, as per your troubles. There was a recall on the dodge Chargers for this same MIL...Description Flash: MIL Illumination DTC P013A/P013C O2 Sensor Slow To Respond.

Not sure what the fix is if you have the new O2 sensor on. Maybe you need another OEM O2 sensor from the stealership? Or an HP Tuned program can just shut off the O2 sensors, hence no MIL.

I think the folks at Superchips need to release a tune with the O2's shut off, and we can use headers then, maybe not the optimal tune, but certainly good enough to run.

I talked at length today with Steve from Solo and the manager from the shop. The shop manager said the new ACDelco 02 sensor was slightly faster than the OEM sensor and it triggered the code. Both Solo and the shop thought that this would resolve itself over the next week or two once the computer "learns" the setup. There is nothing wrong with either sensor. They tested them thoroughly today. They reset it and it hasn't come back on yet. Hopefully it will stay that way. I also raised a little stink because the tech didn't follow the manufacturers instructions. Well they did today and the exhaust is lined up pretty good (not perfect, but then again I have OCD for this stuff) and more importantly it sounds completely different now. For the better!

Strangely, while the Cortex did report this code, it had no description. I got the description off of the corvette forums and just "assumed" all gm V8's would be the same.

The codes are actually universally used for all manufactures on all platforms. Ie the code P0413 for efficiency of the rear O2's is the same for GM, Ford, Dodge and so on.
