About a week ago my CEL and TCS light came on so I pulled the code and it pulled a 42. Rear upstream O2 sensor heater. So I ordered new sensors from SOS that should be here today. I went outside today to move the car and my battery is dead. It will turn the engine over a couple of times and then nothing and all the dash lights light up. I have read that the NSX will do strange things if the battery is weak. Do you guys think this was a coincidence or that the low battery triggered the code? I guess I will know for sure when I get the new battery but I can't do that right now. I am just curious as to if anyone had something like this happen.
CEL light & TCS light AND now a dead battery-coincidence?
- Thread starter SDM214
- Start date
I would do a charging system check once you get the new battery installed.
Since you already have the O2 sensors showing up I would go ahead and replace them as they don't last forever.

That is a good suggestion. I installed the new battery last night and it took every bit of 10 seconds for the CEL & TCS lights to come back on so I guess that answered my coincidence question. I will replace the O2 sensors this weekend.
