Keep the charging system and intelligent Battery Management System (BMS) working with accurate readings from the Standard Ignition Battery Current / Volt Sensor (BSC121) — a direct-fit OE replacement for the 2020-2023 Nissan Rogue (L4-2.5L), 2021-2023 Nissan Rogue (L3-1.5L), 2022-2023 Infiniti QX60 (V6-3.5L), and 2022-2023 Nissan Pathfinder (V6-3.5L). It's classified as a Battery Current Sensor and listed in the manufacturer copy as a Battery Current / Volt Sensor, so you may find it under either name.

  • Works with the BMS: detects low or insufficient electrical voltage in unison with the vehicle's Battery Management System.
  • Feeds the vehicle computer: its input lets the computer adjust charging voltage, idle speed, and other parameters — helping support fuel efficiency and battery life.
  • Built for the underhood environment: durable materials help it withstand engine-compartment conditions and contamination.
  • Start/Stop friendly: the type of battery sensor increasingly used on newer Start/Stop-equipped vehicles.

Connection details: a single rectangular female plug connector with 2 male pin terminals. Contents: sensor only; mounting bracket(s) are not included — consult the vehicle service information for the correct hardware. Country of origin: Hungary. Manufacturer part number BSC121.
