P0057 2003 Nissan Altima Sedan Code - HO2S22 Heater Control Circuit Low
Quick Answer
Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. Common causes include Faulty Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2, Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2 harness is open shorted, Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2 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 P0057 2003 Nissan Altima Sedan Description
In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen 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 P0057 2003 Nissan Altima Sedan?
- Faulty Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2
- Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2 harness is open shorted
- Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2 circuit poor electrical connection
- Heated Oxygen Sensor (H2OS) Bank 2 Sensor 2 circuit fuse
- Faulty Engine Control Module (ECM)
How to Fix the DTC P0057 2003 Nissan Altima Sedan?
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.
