What is the fix for a po153 code?

Welcome to!

The P0153 is a fairly straight forward code pointing to a failing Oxygen Sensor at Bank2 Sensor1. Inspect the wire harness and connector for any loose, broken or rubbed through wires. Make sure there are no exhaust leaks in the system. If the visual inspection checks ok, suspect a faulty sensor, and replacement should solve the problem. Very common.
