  • My 05 Nissan Armada just stopped on me today. Tried cranking but won't. Gave a code P1031. Please help

  • The code is for a Air Fuel Ratio Sensor 1 Bank 1, but that sensor won't cause the engine to stall. Even if you disconnect the sensor, the engine will still run.
    Start by checking if there is fuel in the fuel tank, the Armada has many problem with the fuel gauge and sometimes it may show that the tank still has gas.

  • Had p1031 code on 2008 nissan xterra, change bank 1 o² sensor, but code is still there.
