Check Engine Light after new exhaust install

[Rocket Scientist]

The OBD port is a socket on the end of a wire that sits in a little clamp on the left side of the battery. Grab the wire close to the plug and gently wiggle it up and out.

I know that I plugged it in. I will verify later today that it is making good contact or fully plugged in but I seem to remember hearing it click. I will also plug in my OBDII reader. Where is the port that I need to plug in to??? Let me know. Thanks

So the ces header (collector) has a threaded port for the O2 sensor? If so, the cable from the sensor connects to a cable from the ECU under the right cover. That circuit has to be complete. As noted, the cable from the ECU for plugging in an OBDII reader is to the left of the battery.

if u had any thing disconnected and u turned on the ign causes instant code.
if this is the case clear codes and u will be ok

I connected everything before turning on the ignition, but I am wandering if I possibly disrupted a wire or something when I moved the module out of the way when I disconnected the O2 sensor wire connector. I guess I just need to check what code/s come up on my scanner before I get too far into the weeds. It does have me a little baffled though!

there's a possibility with a new exhaust/removing & fitting exhaust that the o2 sensor cable has come into contact with the pipes during running and melted wires. i'd follow the o2 sensor cable from exhaust bung up to be sure.
assuming the cable is ok then the highest probability for check light is the AFR spec was not achieved due to new exhaust

I don't think I melted any wires as I routed them the same way they were routed originally, but I will verify it this evening when I get home. I am hoping that it is just an Air Fuel Ratio problem or something simple like that. I will check code/s, clear codes and try again!

Yeah, the first thing that you need to do is find out what the ECU is b****ing about before getting over stressed about potential causes. I just installed a Reband on my 13 R3T which promptly threw a P0130 oxygen sensor code during the 12 minute tune after loading a updated tune in it. Said WTF, cleared it and went riding. The bike ran fine and 400 miles later the CEL still hasn't returned. I attribute it to the new pipe and sealant on the collector out gassing and causing the O2S to not return the data that the ECU was looking to see.

If your code reader supports data stream display that will be helpful if the code resets. Probably want to get TuneEcu anyway though. It isn't up to the level of Tune Boy but for 29 bux (what I paid for the cable) it is hard to beat for the money. Besides that you are probably going to have to load a new tune in to her anyway. Unless there is a tuner near to you that can do a custom map for you.

Pulled the seat off and side panel and checked the O2 wiring and the other connections in that area and everything looked good. Read the code, and it was P0030- O2 Sensor Heater Circuit. I cleared the code restarted and after about a minute it came back on again, thinking that it could be what you mentioned about sealants and gasses from new exhaust and stuff so I revved it a couple times and shut it back off cleared the code and restarted it again. I let it idle for about 15 minutes and the light never came back on, so I took it for a little ride about 5 miles total and the light never came back on! I do think it needs a tune though as it is backfiring out the exhaust on deceleration. So with that I think I was getting excited for nothing! Let's hope anyway! Thanks everyone for your suggestions and help.

Good work trouble shooting.

Really, as much as you want to ride it, don't until you get a tune. The CES pipes are not like bolting on a slip-on, you need a whole new tune for both the safety of the motor and the extra power the CES pipes can deliver.

Just curious here . . .
@zman8537 when installing the CES, did you also change out your stock intake as well?
