34830-87J20 Suzuki 5034087 Johnson Exhaust Temp Sensor | Genuine Used Part

🔧 Product Description

Genuine Suzuki / Johnson Exhaust Temperature Sensor - Part Numbers: 34830-87J20 / 5034087

A genuine used exhaust or engine-temperature sensor for Suzuki four-stroke outboards and corresponding Suzuki-built Johnson and Evinrude engines.

The sensor monitors exhaust-passage or cylinder cooling temperature. The ECU uses the signal to trigger overheat warnings and protective reduced-power operation when an abnormal temperature is detected.
