P0052 2007 Nissan Sentra Code - Air Fuel Ratio Sensor 1 Heater Bank 2 Control Circuit High
Quick Answer
Air-Fuel Ratio (A/F)sensor need to reach a minimum operating temperature of 1200 degrees F to produce an accurate voltage signal. Common causes include 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. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0052 2007 Nissan Sentra 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 2007 Nissan Sentra?
- 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)
How to Fix the DTC P0052 2007 Nissan Sentra?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
