I've checked my fault codes today with a little trick I learned from this forum.

15 & 23 are the fault codes.

15- Oxygen sensor or circuit
23- Rear o2 sensor inactivation error

Inactivation errors 15 (left) & 23 (right) indicate the sensor never "woke up" from cold.
Cold sensors produce little or no output voltage.

And with that it means that I should check and in worst case change my oxygen sensor I guess?
The only thing I was wondering is why its rear sensor(right) and left, is it 2 oxygen sensor for probe?

I've been trying to figure out this exact problem on ours for a few months now. Replaced the rear O2 sensor, but no change...
