I have a NGK AFX with NTK sensor perm mounted in my LSA. It it powered at key on. I have read that cold start (rich / moisture) can shorten the life due to thermal shock of liquid contacting the ceramic. True or internal fable? Reality is, the car is dormant almost all winter and started to move/make space in garage. I will remove the sensor in the fall if it makes a difference.
Thank you in advance.
