Dphil25gtwagon Posted August 31, 2015 Share Posted August 31, 2015 I bought this car with a Cobb ap, cobb DP, and also a gutted UP. I replaced the DP with the stock one, I uninstalled the AP, and now the car shows a cel for O2 sensor heater circuit low. I also have a green cruise control light flashing. I pulled all this stuff off so I could smog it for change of ownership buthats not gonna happen with the current cel. It seems unlikely, but is it possible the O2 went bad during the swap? Also, I assume the green cruise light is related to the cel coming on as well? Im sure im not the only one who has experienced this? Anyone?

shortfusemonkey Posted August 31, 2015 Share Posted August 31, 2015 my first question would be, when you uninstalled the AP, I assume you changed it back to stock tune? even putting stock DP on, I would have left the AP installed with OTS 1 mapped on ECU.

Redslaya Posted August 31, 2015 Share Posted August 31, 2015 Cruise will flash with a CEL, thats how our cars work. as for the O2 sensor, i would double check it is installed tightly and plugged in. the amount if times ive gotten a CEL for forgetting to plug my MAF back in is inumerable Link to comment Share on other sites More sharing options...
Dphil25gtwagon Posted August 31, 2015 Author Share Posted August 31, 2015 my first question would be, when you uninstalled the AP, I assume you changed it back to stock tune? even putting stock DP on, I would have left the AP installed with OTS 1 mapped on ECU. I was afraid this was coming. I did not change it back to stock tune. I was under the impression that by uninstalling it, it would go back to factory settings. I read it somewhere. So hopefuly i ll try and reinstall the AP and switch the tune if thats how it works. All this Cobb stuff is new to me right now since i just bought the car with it. Looks like ill learn the hard way, dammit. Link to comment Share on other sites More sharing options...
Dphil25gtwagon Posted August 31, 2015 Author Share Posted August 31, 2015 Can anyone confirm that i fucked up by uninstalling the AP without switching the map back to stock? Ill be trying to reinstall in about an hour so i hope it goes back to how it was. At least then I can leave the AP installed and switch to the stock tune.

whitrzac Posted September 1, 2015 Share Posted September 1, 2015 02 sensors fail all the time. Especially when being taken out and put back in a few times. Link to comment Share on other sites More sharing options...
Dphil25gtwagon Posted September 1, 2015 Author Share Posted September 1, 2015 http://i18.photobucket.com/albums/b116/4cfedz31/Mobile%20Uploads/ADF8A882-E297-4AB8-9161-1C7392AD24A6_zpspzxrbsyp.jpg So here is what I found. Looks like whoever did the DP install had to cut the heat shield a little to keep it away from the O2. Looks like it frayed the wires a bit. Let's hope that's the problem. I'll order a new one tomorrow. Link to comment Share on other sites More sharing options...
