Cost of diagnosing the P0031 2012 NISSAN ROGUE code
Labor: 1.0The cost of diagnosing the P0031 2012 NISSAN ROGUE code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the P0031 2012 NISSAN ROGUE code detected?The P0031 is set when the ECM detects an excessively low voltage through the heated oxygen sensor heater circuit
P0031 2012 NISSAN ROGUE Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P0031 2012 NISSAN ROGUE MeaningAir-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.
