Ok my o2 sensor cel light came on.code p0136Well this happen before and I switched the o2 and was fine,but now my air bag light is on.It didnt come on last time.Any ideas why?

 

PO136 is a O2 sensor malfunction Bank 1 Sensor 2 as you have stated. In other words your second oxygen sensor isnt reading right or its old. Do you have a header or factory manifold? If you have a header, is it after a cat? If its just old and you have the factory mani then replace it.

 

I think its bank1 sensor1 like it was last time.Yes I have headers.Im not going to get new o2 sensor buying one from supercrow soon,cause im going turbo real soon.I just want nothing happening to my air bag.
