What does p0137 mean on an oxygen sensor?

For example, a P0137 on a Toyota translates to “Oxygen Sensor Circuit Low Voltage Bank 1, Sensor 2”; a P0137 on a Chevy, meanwhile, is “Heated Oxygen Sensor (HO2S) Circuit Low Voltage Bank 1, Sensor 2”. Since translations vary, the possible causes may also differ depending on the make and model of your vehicle.

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 causes the O2 sensor circuit low voltage code?

This code occurs when the engine control module (ECM) sees the voltage of the O2 sensor for bank 1 sensor 2 below .21 volts when the ECM has commanded the fuel to a targeted rich condition on that bank of the engine. What causes the P0137 code? The ECM detects the low voltage problem and turns on the Check Engine Light.

What is the O2 sensor code for bank 1?

All our repairs are backed by our 12-month / 12,000-mile warranty. P0137 is the OBD-II generic code indicating the O2 sensor for bank 1 sensor 2 is failing to increase the voltage output above .21 volts indicating excessive oxygen in the exhaust.

What are the symptoms of an O2 sensor circuit low voltage?

Here are the most common causes of an O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2) problem or code P0137: What are the Common Symptoms of the P0137 Code?

What causes the p0137 code on a Dodge Ram?

Here are the most common issues that cause the P0137 code in the Dodge Ram. They are presented in order (somewhat) of most to least likely to cause the problem. Bad Oxygen Sensor – The O2 sensor itself is one of the most likely reasons that P0137 is triggering your service engine soon light.

When is the p0137 sensor circuit low voltage bank 1 detected?

Replacing the rear O2 Sensor bank 1 usually takes care of the problem. What does this mean? When is the code detected? The P0137 code is set when the Engine Control Module (ECM) detects that the rear O2 sensor signal voltage remains excessively low for an extended period of time.

What is the error code for the O2 sensor?

Error Code P0137: O2 Sensor Circuit Low Voltage Bank 1 Sensor 2. When an oxygen sensor in a vehicle starts to have issues, either from a bad fuel mixture or the sensor itself going bad, it will trigger a number of codes in a vehicle computer.

Why is Bank 1 sensor 2 low voltage?

The O2 sensor circuit for bank 1 sensor 2 is used to give a voltage feedback to the ECM showing how much oxygen is in the exhaust stream to help the engine control the fuel-to-air ratio better. The low voltage condition is excessive oxygen in the exhaust or problems causing the issue. Need help with a P0137 code?

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.

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.

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.
