Code P0052 2006 Nissan Pathfinder Description
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.
What are the Possible Causes of the DTC P0052 2006 Nissan Pathfinder?
- Faulty Air-Fuel Ratio (A/F) Sensor Bank 2 Sensor 1
- Air-Fuel Ratio (A/F) Sensor Bank 2 Sensor 1 harness is open shorted to ground
- Air-Fuel Ratio (A/F) Sensor Bank 2 Sensor 1 circuit poor electrical connection
- Faulty Engine Control Module (ECM)
