Shift Indicator Light

[VX_Arky]

I had this problem with my Honda Civic VX and got this question answered on the old GasSavers.org website but since it's gone I want to ask it again.

My friend says his shift indicator light isn't coming on. I tried to explain that more than likely it has to do with the weather not being quite warm enough yet where he lives and that it will begin to work in late April or May. The very same thing happened with my car when it gets cold in November and it does this pretty much until early March. I'm not sure why but I know some of you guys know the answer.

Could someone please explain why the car cannot go into lean burn during the winter months when it's cold? Mine will do it from March Until November but no way in December, January or February.

He thinks something is wrong, and I guess the 02 sensor could have gone bad, but I really don't think that's the problem. Would someone please care to explain this for me here, so he can get the correct answer?

Thanks!
