Ok

This code is for the heater in the rear O2 sensor. Most of the time what happens is the sensors heater element burns out and the sensor needs to be replaced. This is the O2 sensor in the exhaust AFTER the catalytic converter on this model. Likely you will have to get under the car to access it. It's not unusual for the elements to burn out over time.

This is a fairly straight forward repair that you could likely do.

Please let me know if there is anything else I can do to help.
