Official Description: Battery Current Sensor Circuit Range/Performance Common Vehicles Affected: Nissan Altima, Sentra, Rogue, Versa, and Murano (typically models equipped with the HR/MR engine series, roughly 2007–2016). 1. Overview: What is this Code? 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 Battery Current Sensor , which is attached to the negative battery terminal. Contra Operation Galuga Switch Nsp Update Dlc Better
Nissan’s charging logic is sensitive. If your battery is dying or has a dead cell, the voltage fluctuations can cause the current sensor readings to look irrational to the computer. Always test the battery health first. Jk Molester Train Seeding Uncle V21 Digital Work Apr 2026
The sensor is a small electronic unit clamped around the negative battery cable. It is prone to internal failure. If the internal Hall-effect sensor fails, it sends a 0-volt or 5-volt fixed signal to the ECM, which triggers P155B00.
