Code P22AB Description

The P22AB diagnostic trouble code indicates that there is an open circuit in the positive current control circuit of the oxygen sensor located in bank 1, sensor 2 of the vehicle's exhaust system. This sensor is responsible for monitoring the oxygen levels in the exhaust gases after they have passed through the catalytic converter. If the circuit is open, it means that there is a break in the electrical connection between the sensor and the vehicle's engine control module (ECM).
