Came up o2 sensor.

Weird thing is I just swapped motors and on the previous motor there was know check engine light. Using same o2 sensors. I think they broke a pin or it's no plugged in all the way.

Bank one means header o2 sensor?

 

Yes, it's in the exhust manifold.
Just reset the battery and see if the cel comes back or not.

 

Or take it to Autozone and read what the CEL is about....good luck.

 

btw if ur car is under 150k then take it to the dealership and they will swap out the o2 sensor. they will charge u 100 first but return after they check it. Emissions warranty was extended....!!!!!

 

Ok the engine has 90,000mi so what I'm told, but the car has 210,000mi. Does this still apply?

 

Did that bank 1 sensor 02.
