When is a bad air conditioning sensor 1 bank 1 code recognized? The control function of the seat 1 does not work even if the vehicle is driven under certain conditions. Technical information is a service bulletin for the following models:

2005-2006 Nissan Ultima

Nissan Ara 2004

It may be necessary to test the Heater 1 air ratio sensor (A / F) to verify that it is operating within a certain range.

This code is often a problem when the O2 sensor fails or is unable to send information to the ECM. Check O2 sensor and cables and connections. Preferably by a professional with appropriate equipment. Some O2 sensors are expensive.
