What is the diagnostic code for O2 sensor circuit low voltage?
P0131 is a diagnostic trouble code (DTC) for “O2 Sensor Circuit Low Voltage Bank 1 Sensor 1”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
When to replace Bank 1 downstream O2 sensor?
If the O2 sensor is reading high voltage and the fuel pressure and coolant temperature are within spec, replace the bank 1 downstream O2 sensor. For error code P0138, one or more of the below repairs may be needed to solve the underlying issue.
What is the O2 sensor voltage code p0131?
Testing O2 Voltage with a Meter The conditions that set the code P0131 refer to consistently low voltages or sensors that remain fixed at 0 V. As we discussed in previous oxygen sensor diagnosis articles the voltage that’s monitored by the PCM (Powertrain Control Module) should fluctuate rapidly.
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.
Cost of diagnosing the P0137 code. P0137 is a diagnostic trouble code (DTC) for “O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
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 does it mean when O2 sensor stops working?
Hence, This means the sensor is operating properly. If the (O2) sensor only produces a low or high voltage signal. So, either you have an engine performance issue or the (O2) sensor stopped working. Finally, To verify sensor operation, conduct the next two tests.
Testing O2 Voltage with a Meter The conditions that set the code P0131 refer to consistently low voltages or sensors that remain fixed at 0 V. As we discussed in previous oxygen sensor diagnosis articles the voltage that’s monitored by the PCM (Powertrain Control Module) should fluctuate rapidly.
