What code is P0137?

What Does P0137 Mean? Oxygen sensor 2 is the downstream oxygen sensor in relationship to the catalytic converter. When trouble code P0137 is set, this indicates that there is low voltage (roughly 450 millivolts or less) for more than 20 seconds coming from the bank 1 sensor 2 oxygen sensor.

Is P0137 upstream or downstream?

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. There are two O2 sensors in your vehicle. The sensor located before the catalytic converter is the upstream sensor, also known as Sensor 1.

What can cause low O2 sensor voltage?

The voltage output from the O2 sensor may be due to exhaust leaks causing the O2 sensors to give low output voltages. The ECM cannot correctly control the fuel-to-air ratio of the engine fuel mixture if any O2 sensor is malfunctioning.

What does the low voltage code p0137 mean?

More specifically, this means that the PCM is detecting a low voltage from the #2 O2 sensor in Bank 1. Code P0137 triggers when the PCM detects that the signal from oxugen 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.

When does a bank 1 O2 sensor code p0137 occur?

Code P0137 is generated when the engine control module (ECM) detects that the O2 oxygen sensor for Bank 1 voltage has remained below 400 millivolts (0.21 volts) for more than twenty seconds. Another reason for this code to occur is that the air/fuel ratio sensor remains lean mode for over 2 minutes. The duration varies from car to car.

When does p0137 trigger in a catalytic converter?

In contrast, downstream sensors (sensor 2) generate a fairly steady voltage when the catalytic converter is working properly. Code P0137 triggers when the PCM detects that the signal from sensor 2 on Bank 1 was below a specific value for a certain amount of time.

What is the p0137 code for oxugen sensor 2?

Code P0137 triggers when the PCM detects that the signal from oxugen 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.
