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 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 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.
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?
