In most cases the fix is. [archive] a year of p0137… nc general discussion for fault code p0137 the pcm is looking at the voltage on terminal 2q of the pcm If the ecu detects that the actual oxygen signal wire in bank 1, sensor 2 is registering a low voltage below 400 milli volts for more than 20 seconds, it will trigger the p0137 code.
P0131,P0137,P0151,P0157 O2 Sensor Circuit Low - Obd2-code
Don’t just replace the sensor
Master the diy steps to accurately diagnose the p0137 code, testing the circuit, wiring, and exhaust for the true cause.
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. Replacing the downstream o2 sensor fixes p0137 in 70% of cases, but always check for a blown heater fuse first to save $150 Inspect the exhaust system for soot marks or ticking sounds.
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. For fault code p0137 the pcm is looking at the voltage on terminal 2q of the pcm If the voltage goes below 0.1 volt for >35 seconds fault code p0137 is tripped.
Fix p0137 o2 sensor low voltage
Get detailed steps on identifying bank 1 sensor 2 issues, checking wiring, pinpointing leaks, and completing the repair. O2 sensor circuit low voltage (bank 1, sensor 2) — low severity The ecm has detected that the downstream oxygen sensor (bank 1 sensor 2) voltage is stuck low, consistently reading below the expected minimum threshold The p0137 code indicates a problem with the o2 (oxygen) sensor circuit, specifically a low voltage reading from bank 1 sensor 2
A p0137 code is set when the computer (ecm/pcm) detects low voltage on the bank 1, sensor 2 oxygen sensor If the engine is in a lean running condition it can set a p0137 code. The powertrain control module (pcm) supplies a voltage of about 450 mv between the ho2s high and low signal circuits The oxygen sensor varies the voltage over a range from about 1,000 mv when the.
Diagnostic trouble code p0137 indicates that the #2 oxygen sensor, located along bank 1, is producing lower than expected voltage
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 Full diagnostic guide + 2026 repair costs. The purpose of the oxygen sensor is to measure the oxygen content in the exhaust gases after they leave the combustion. This is one of the most frequent obd2 trouble codes
Read the full article below to know what it means, how to fix it, and what other codes may show related to it. The p0137 code specifically translates to “o2 sensor circuit low voltage (bank 1 sensor 2),” targeting the sensor positioned after the main catalytic converter.
