866834 Pressure Sensor | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta 0 to 10 bar pressure sensor for double instruments, from the Instruments group, weighing 0.136 kg and listed for 15 applications across TAMD and TMD series engines. It supersedes 843232, catalogued earlier as an oil pressure sensor. The double-instrument arrangement is what sets it apart from 866833, which is published at the same 0.136 kg, so weight is no guide here.

• One of the two instruments disagreeing with the other
• Oil weeping from the sensor body or its thread
• Corroded or green terminals at the connector
• Readings that change when the connector or harness is moved
