Code P0152 2003 Nissan Sentra Description
The P0152 diagnostic trouble code for a 2003 Nissan Sentra indicates a problem with the Air Fuel Ratio Circuit High Bank 2 Sensor 1. This means that the oxygen sensor located in bank 2, which is typically the side of the engine where cylinder 2 is located, is reporting a higher than normal voltage signal to the Engine Control Module (ECM). The ECM uses this sensor to monitor and adjust the air-fuel mixture for optimal combustion. When the sensor reports a high voltage signal, it could indicate a rich air-fuel mixture, potentially leading to decreased fuel efficiency and increased emissions.
Common Causes of P0152 2003 Nissan Sentra
- Faulty oxygen sensor
- Wiring or connector issues
