Multiquip 8981783581 DOC Temp Sensor Front - OEM Replacement Part

The DOC temperature sensor monitors exhaust gas temperature at the front of the Diesel Oxidation Catalyst (DOC) in Tier 4 Final compliant generators. This sensor provides critical input to the engine control unit for emissions system management, DPF regeneration control, and engine protection. Failure symptoms include regeneration issues, engine derating, fault codes related to aftertreatment temperature monitoring, or complete engine shutdown in protection mode.

Designed specifically for Multiquip's Super Silent generator line, this front-mounted DOC temperature sensor ensures accurate exhaust temperature monitoring for optimal emissions compliance and reliable operation. The sensor integrates directly with the Tier 4 Final aftertreatment system to maintain proper regeneration cycles and prevent component damage from excessive temperatures.

• DCA125SSIU4F
• DCA70SSIU4F
