What does this code mean P0137?
Oxygen sensor 2
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.
How many O2 sensors does a 2006 Toyota rav4 have?
However, most of the later model vehicles have four oxygen sensors.
What does 02 sensor circuit low mean?
Diagnostic trouble code (DTC) P0131 stands for “O2 Sensor Circuit Low Voltage (Bank 1, Sensor 1).” It indicates that the voltage of the affected oxygen sensor stayed below a certain threshold or the air-fuel ratio sensor stayed in a lean-biased mode for too long.
How many o2 sensors does a Toyota rav4 have?
Oxygen sensors are located before and after the catalytic converter. A vehicle may have two to five oxygen sensors, and sometimes even more.
What causes the p0137 code on a Toyota RAV4?
Here are the most common issues that cause the P0137 code in the Toyota Rav4. 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.
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.
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.
