How to fix P1168 - Closed Loop Control Function Bank 2

Question

How to fix code P-1168 Closed loop,bank 2.

Answer 1

Hi there,

This code means the front A/F sensor on bank 2 isn't going into closed loop. This is usually a result of the sensor itself. This is the first O2 sensor BEFORE the catalytic converter on bank 2. This is the bank closest to the radiator.
