In most cases the fix is.
Learn what the p0137 o2 sensor code means, common causes, symptoms, and repairs Find out if it’s safe to drive and how to fix it fast. Fix p0137 o2 sensor low voltage Get detailed steps on identifying bank 1 sensor 2 issues, checking wiring, pinpointing leaks, and completing the repair.
This sensor sits immediately after the catalytic converter to monitor its efficiency by measuring exhaust oxygen content A low voltage reading (under 0.2v) tells the pcm there is excess. In simpler terms, this code indicates that the engine control unit (ecu) is receiving a low voltage signal from the upstream oxygen sensor, which can. P0137 means the downstream oxygen sensor on bank 1 (sensor 2) is reading abnormally low voltage — below 0.4v for 20+ seconds
