🔧 Product Description

Genuine Volvo Penta 0 to 3 bar sensor from the Instruments group, weighing 0.141 kg and listed for 82 applications across TAMD, AD, D, TMD, HS and KAMD series engines. It supersedes 862254. The 0 to 3 bar range is what separates it from the 0 to 2, 0 to 10 and 0 to 30 bar sensors listed alongside it, and a mismatched range reads smoothly and reads wrong.

⚠️ Common Signs of Failure

• Gauge reading zero, pegged or wandering with pressure confirmed good
• Fluid 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
• A reading that looks plausible but does not match a mechanical gauge
