P0137: O2 Sensor Circuit Low Voltage (Bank 1 Sensor 2) - OBD ADVISOR
P0137 means your downstream oxygen sensor on bank 1 — the one mounted after the catalytic converter — is reading too low for too long
In most cases the fix is.
Fix p0137 o2 sensor low voltage Get detailed steps on identifying bank 1 sensor 2 issues, checking wiring, pinpointing leaks, and completing the repair. The p0137 code sets when the sensor’s signal voltage consistently falls below the predetermined low threshold, which is often around 0.1 or 0.2 volts, indicating a problem with the. I checked the voltage of the secondary o2 sensor on the application, and it seems to be functioning as expected (when i floor it, the downstream o2 sensor voltage rises, when i don't floor it,.
When its voltage consistently drops below a certain threshold, it signals that something may be wrong with the sensor itself, the wiring, or the exhaust system This code does not always mean the sensor. Code p0137 indicates a persistently low voltage reading from the downstream oxygen sensor (sensor 2), which is located immediately after the catalytic converter to monitor its efficiency. P0137 means the downstream oxygen sensor on bank 1 (sensor 2) is reading abnormally low voltage — below 0.4v for 20+ seconds
The most common fix is replacing the.
The purpose of the oxygen sensor is to measure the oxygen content in the exhaust gases after they leave the. The p0137 code stands for oxygen sensor circuit low voltage (bank 1, sensor 2). this sensor monitors the oxygen levels in the exhaust to. Learn all about the p0137 code, what causes o2 sensor circuit low voltage, and how to diagnose and fix common issues to maintain optimal engine performance. What does the p0137 code mean
The p0137 code indicates there’s a fault with the second oxygen sensor located on bank 1 What does the p0137 oxygen sensor circuit low voltage (bank 1, sensor 2) mean P0137 code gets triggered when the engine control module. The p0137 code points to a downstream o2 sensor issue
Learn the causes, symptoms, and fixes, and find out if it’s safe to.
Full diagnostic guide + 2026 repair costs. If your check engine light is on and you’ve got a p0137 code, that means the oxygen sensor located after the catalytic converter (bank 1, sensor 2) is reporting a low voltage reading
