Honda 31610-Z4T-843ZB Control Box Assembly (EXP-Alert) (Power Red)

The Honda 31610-Z4T-843ZB Control Box Assembly (EXP-Alert) (Power Red) is a genuine OEM component designed for GX160 and GX200 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the same standards as the original unit it replaces, ensuring a proper fit without modification. This assembly carries the Power Red finish and EXP-Alert designation — match both the color and alert variant to your existing unit before ordering, as Honda lists multiple control box variants across these engines. Verify your engine's serial number against the fitment table to confirm this is the correct assembly for your application.

Key Features

• Genuine Honda OEM Assembly — sourced directly from Honda, this control box assembly meets the same specifications as the original unit, ensuring the engine protection and control functions perform as intended.
• EXP-Alert System Integration — built specifically for Honda's EXP-Alert engine protection platform, which monitors operating conditions and shuts down the engine to prevent damage under fault conditions.
• Power Red Variant — the Power Red finish is a variant identifier; confirm your machine carries this color designation before purchasing, as alternate-color versions are separate parts.
• Fits GX160 and GX200 Engines — compatible with GX160 and GX200 horizontal shaft engines across applicable serial ranges; check your serial number against the fitment table to confirm applicability.
• Direct OEM Replacement — replaces a failed or damaged control box assembly with a part built to Honda's original design, restoring full engine protection and control operation.

The control box assembly houses the electronic control circuitry that manages engine protection and operational functions on GX160 and GX200 horizontal shaft engines equipped with Honda's EXP-Alert system. This system monitors engine parameters and intervenes — typically by shutting the engine down — when a fault condition is detected, protecting the engine from damage that would otherwise result from running under abnormal conditions. When the control box fails or is damaged, the engine may not start, may shut down unexpectedly, or may lose its protection functions entirely; replacing it with the correct Honda OEM assembly restores normal operation and system integrity.
