: Have a professional load test performed to ensure the battery is holding a charge properly. Inspect the Sensor

The most frequent cause is a faulty battery current sensor, which manages the alternator's output to the battery.

Check the wiring and connectors for the upstream and downstream NOx sensors under the chassis for physical damage or loose connections.

Nissan vehicles utilize a "Deceleration Fuel Cut System." To make this system work efficiently, the Engine Control Module (ECM) needs to know exactly how much power the alternator is putting out. It does this via the , which is attached to the negative battery terminal.

Ensure the battery is in good health and has at least 12.6V12.6 cap V when the car is off.
