How To Fix P0137 Code Code p0137 triggers when the pcm detects that the signal from oxygen sensor 2 on bank 1 is below a specific value for a certain amount of time. the bank 1 portion of the code refers to the side where the #1 cylinder is located. there are two o2 sensors in your vehicle. the sensor located before the is the upstream sensor, also known as sensor 1. The first step in diagnosing a p0137 code is to inspect the oxygen sensor. this sensor is located in the exhaust system and measures the amount of oxygen in the exhaust gases. if the sensor is faulty, it can cause the low voltage reading that triggers the p0137 code. to inspect the oxygen sensor, you will need a multimeter.
Engine Code P0137 P0520 code: engine oil pressure sensor switch circuit. learn about the p0520 code, which signals a problem with your engine's oil pressure sensor or circuit. discover symptoms, causes, and repair tips. read more. The p0137 code indicates there’s a fault with the second oxygen sensor located on bank 1. the oxygen sensor’s voltage was too low for at least two minutes, which is why the code was set. the ecm is responsible for reading the voltage and setting the code. bank 1 sensor 2 is found towards the back of the catalytic converter. Diagnosis: driving with trouble code p0137 is acceptable but only for a short period of time. driving with this code for an elongated period of time could result in greater engine damage if it is being caused by a lean air fuel ratio. common reason: code p0137 is often related to a bad o2 sensor. oxygen sensor 2 is the downstream oxygen sensor. The p0137 is triggered when the downstream o2 sensor (bank 1) voltage is lower than 0.21v for longer than 2 minutes. in many cases, it can be because your downstream o2 sensor is faulty. downstream oxygen sensors (located after the catalytic converter) monitor the conditions of the catalytic converter. the more air in the exhaust gas (after.
