p0137- low voltage signal oxygen sensor-bank 1, sensor 2. Since our cars only have 2 sensors (there is no bank 2), this indicates a problem with the post-converter oxygen sensor. Usually low voltage codes indicate a bad/dirty sensor and replacement will cure the issue. You may still want to inspect the wiring to it also, just in case.
