Industrial 34830-87J20 Exhaust Temperature Sensor

The Suzuki 34830-87J20 Exhaust Temperature Sensor is an OEM exhaust temperature sensor assembly (SENSOR, EXHAUST TEMP) for Suzuki outboard engines. The part is listed in Suzuki Marine Parts catalogs as 34830-87J20, with a common variant 34830-87J20-0000, and is identified as the Exhaust Temp Sensor Assembly in model diagrams. It is used to monitor exhaust gas temperature and relay measurements to the engine control unit to support accurate fuel metering, timing, and emissions management across a range of DF-series outboards (including DF200A/DF300-series and other DF engines). By providing real-time exhaust temperature data, the sensor enables ECU-driven protection modes and diagnostics to maintain engine performance in marine applications. As an OEM Suzuki replacement, 34830-87J20 is the standard part for maintaining the exhaust-temperature sensing capability on affected Suzuki outboards per official catalog references.
