X AUTOHAUX Battery Current Sensor & Cable for Honda Accord 2013–2017 — OEM-Equivalent, Direct-Fit

If your 2013–2017 Honda Accord is showing charging warnings, erratic gauge readings, or battery-related fault codes, a worn or failing battery current sensor (also called a battery monitor sensor) can be the cause. The X AUTOHAUX sensor and cable assembly fits Accord models from these years and carries OEM-equivalent part numbers 38920-T2A-A02, 38920-T2A-A03 and 38920-T2A-A04. Constructed from durable plastic and metal, the unit measures electrical parameters and feeds that information to your vehicle's charging and engine-control systems so they can maintain stable voltage.

How does this sensor affect my Accord’s charging system?

The battery current sensor measures battery voltage, current flow and temperature so the ECU can adjust alternator output and charging strategy. Without accurate readings, the alternator may under- or over-charge the battery, triggering dashboard warnings or reduced battery life. Replacing a faulty sensor helps restore correct charge regulation.

• Monitors battery voltage and current to inform the ECU
• Reports battery temperature for safer charging behavior
• Helps prevent charging irregularities and related fault codes
• Compatible with Accord electrical architecture 2013–2017

What parts and fitment information should I know?

This assembly is designed specifically for Honda Accord model years 2013 through 2017 and corresponds to the OEM numbers 38920-T2A-A02, 38920-T2A-A03, and 38920-T2A-A04. Confirm compatibility by comparing your vehicle’s part number or asking a mechanic before purchase. The replacement is a direct-fit style intended to match factory connections.

• Fitment: Honda Accord 2013–2017
• OEM-equivalent part numbers: 38920-T2A-A02 / A03 / A04

How difficult is installation and what tools are required?

Installation is straightforward for anyone comfortable working around the battery area. Basic hand tools are required to disconnect the negative cable, remove mounting bolts, swap the old sensor for the new unit, and re-secure connections. Follow safety steps such as disconnecting the negative battery terminal first.

• Step 1: Disconnect negative battery cable and loosen retaining bolt
• Step 2: Remove bolts on the wiring bracket and free the assembly
• Step 3: Replace the sensor, reconnect bolts and cables securely
• Tools: wrench or socket set, screwdrivers as needed

What is the construction and durability of the unit?

The X AUTOHAUX battery current sensor is built from a blend of plastic housing and metal contacts to balance durability with electrical stability. The materials are chosen to withstand typical underhood conditions—vibration, temperature changes, and exposure to automotive environments—so it delivers reliable readings over time when installed correctly.

• Plastic housing resists corrosion and insulation wear
• Metal cores and terminals ensure stable electrical connections
• Engine bay-rated components for long-term reliability
• Designed to match factory mounting and cable routing
