When is the P0031 2010 NISSAN SENTRA code detected?The P0031 is set when the ECM detects an excessively low voltage through the heated oxygen sensor heater circuit
P0031 2010 NISSAN SENTRA Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P0031 2010 Nissan Sentra DescriptionAir-Fuel Ratio (A/F)sensor need to reach a minimum operating temperature of 1200 degrees F to produce an accurate voltage signal. The faster the air-fuel ratio sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM).
In order to achieve the require temperature, a heater element is included inside the air-fuel ratio sensor. The ECM controls the air-fuel ratio sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground.
The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.
