Multiquip 8981867621 DOC Temp Sensor Front and Rear - OEM Replacement Part

The DOC temperature sensor monitors diesel oxidation catalyst temperatures at both the front and rear positions, providing critical data to the engine control system for emissions management and regeneration control in Multiquip super silent generators. This dual-position sensor ensures accurate temperature readings across the DOC system, enabling proper diesel particulate filter (DPF) regeneration cycles and preventing overheating or incomplete regeneration that could damage the aftertreatment system.

Designed for Multiquip's Tier 4 Final compliant super silent generators, this sensor is essential for maintaining emissions compliance and protecting expensive aftertreatment components. Failed or inaccurate DOC temperature sensors can trigger fault codes, prevent regeneration cycles, and lead to excessive soot buildup in the DPF. Regular inspection and replacement of this sensor ensures reliable emissions system operation and prevents costly downtime.

Compatible with the following Multiquip generator models:

• DCA125SSIU4F
• DCA400SSI4F
• DCA400SSI4F3B
