Battery Sensor X4XZ for Honda Civic/CRV & Acura ILX/RDX 38920-TR0-A02

Description

Product Overview

The X4XZ battery current sensor is engineered to deliver high‑precision monitoring of automotive battery systems. Built from premium copper alloy conductors, the sensor offers superior electrical conductivity and resistance to corrosion, ensuring long‑term reliability even under the demanding conditions of daily driving. Its digital output provides clear, real‑time data on current flow, voltage levels, and the overall state of charge, allowing vehicle owners and technicians to quickly assess battery health. The sensor is designed to replace the original equipment part OE# 38920-TR0-A01, fitting seamlessly into the existing wiring harness of compatible Honda and Acura models. With a compact flange‑mount form factor measuring just 3.62 x 3.62 x 3.23 inches and weighing only 5.6 ounces, it integrates discreetly into the engine compartment without interfering with other components. The device operates at a maximum supply voltage of 12 V and maintains an accuracy of ±1 %, meeting the stringent standards required for modern automotive electronics. Its robust construction, rated for temperatures up to 125 °C, guarantees stable performance across a wide range of climates, from scorching summer roads to frigid winter environments.

Usage

Designed specifically for 2012‑2016 Honda Civic, 2012‑2016 Honda CRV, 2013‑2021 Acura ILX, and 2013‑2018 Acura RDX, this sensor fits into the battery monitoring system of each vehicle without the need for extensive modifications. Installation involves disconnecting the negative battery cable, removing the original sensor, and securing the new X4XZ unit with the provided bolt wrench. The pigtail connector aligns precisely with the factory wiring, ensuring a tight, vibration‑resistant connection that will not loosen over time. Once installed, the sensor continuously tracks the flow of current to and from the battery, providing valuable data that can be accessed through the vehicle’s onboard diagnostics or a compatible aftermarket gauge. This information helps drivers detect early signs of battery degradation, prevent unexpected power loss, and optimize charging cycles for improved longevity. The sensor is also suitable for hybrid variants of the Acura ILX, where accurate current measurement is critical for managing the interaction between the internal combustion engine and the electric drivetrain.
