Question

I have a Nissan with engine code P1051, what is the meaning of the code?

Answer 1

Hi there,

This code is for a faulty heater circuit on the bank 2 O2 sensor, sensor 1. Depending on which model the veicle is there may be a bulletin for the sensor and it's replacement. Most of the time the sensor itself is the cause of the problem and needs to be replaced.

Answer 2

P1051 NISSAN - Air Fuel Ratio Sensor 1 Heater Control Circuit Low Bank 2
