Multiquip V22827993 NOX Sensor

The Multiquip V22827993 NOX Sensor is a genuine OEM component designed for DCA600SSV4F3B and DCA600SSV4F3PB super-silent diesel generators. As a direct OEM replacement, it meets the original engineering specifications required to keep emissions control systems functioning correctly on these large-output units. Verified fitment includes the DCA600SSV4F3B and DCA600SSV4F3PB 60 Hz configurations, so you can order with confidence knowing this is the correct part for your machine.

Key Features

• Genuine OEM Accuracy — Sourced directly from Multiquip, this sensor matches the original output range and signal characteristics required by the engine control system on these generators.
• Direct Drop-In Replacement — Engineered to connect to the existing sensor port and wiring harness without adapter modifications, streamlining the swap during service.
• Confirmed Fitment — Compatible with DCA600SSV4F3B and DCA600SSV4F3PB super-silent diesel generator models, including the 60 Hz variant.
• Emissions System Integrity — A correctly functioning NOX sensor ensures the engine management system receives accurate nitrogen oxide readings, maintaining proper fuel trim and combustion efficiency under load.
• Regulatory Compliance Support — On Tier 4 Final diesel equipment, an accurate NOX sensor is essential to meet EPA emissions requirements; a failed or degraded sensor can trigger fault codes and force the unit into derate mode.

A NOX sensor monitors nitrogen oxide concentration in the exhaust stream and sends real-time data to the engine control unit. On Tier 4 Final diesel generators like the DCA600SSV4F3B and DCA600SSV4F3PB, this information is used to regulate aftertreatment systems — such as selective catalytic reduction — to keep emissions within legal limits. When the sensor degrades or fails, the ECU loses accurate feedback, which can result in fault codes, reduced power output, or automatic shutdown, taking the generator offline until the issue is resolved.
