Details of the Ford p0151 OBD Code
Ford code P0151 indicates an issue with the oxygen sensor circuit low voltage for bank 2 sensor 1.
OBD code P0151 for Ford vehicles indicates an issue with the O2 sensor circuit low voltage for bank 2 sensor 1. This code is triggered by the Engine Control Module (ECM) when it detects a voltage signal from the upstream oxygen sensor (sensor 1) in bank 2 that is lower than expected.
The O2 sensor is part of the emissions control system and helps the ECM adjust the airfuel mixture for optimal combustion.
A malfunction in this sensor can lead to poor engine performance and increased emissions.
Mechanic’s Tech Notes
Detailed information on Ford code P0151, which indicates an issue with the oxygen sensor circuit low voltage for Bank 2 Sensor 1.
OBDII code P0151 for a Ford indicates an issue with the oxygen sensor circuit low voltage for bank 2 sensor 1. To diagnose, start by visually inspecting the wiring harness and connectors for any damage or corrosion.
