When is the p0137 sensor circuit low voltage bank 1 detected?
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 does the p0137 code mean on a car?
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. The heated oxygen sensor 2 (HO2S), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank.
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.
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.
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 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.
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.
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?

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.
