At your mileage, you should replace all 4 02 sensors. That being said, this is not causing your overheat issues and this needs to be addressed ASAP. Have you been having to add coolant lately, or smell it?

Read your owners manual, LR recommends replacing the coolant EVERY 45,000 miles or 36 months, whichever is sooner.
