🔧 Product Description

Genuine Volvo Penta oil pressure sensor from the Instruments group, weighing 0.177 kg and listed for 220 applications across the DPX and B families. It supersedes 3853800 and 872063, both of which were catalogued simply as pressure sensors, so this is now the single number for that role.

⚙️ Key Features

• 0.177 kg
• 220 applications across DPX and B
• Supersedes 3853800 and 872063
• Instruments group

🔌 Function

Measures oil pressure and sends it to the gauge or control system, so a falling pressure raises the alarm before damage is done.

⚠️ Common Signs of Failure

• Gauge reading zero, pegged high, or wandering with no mechanical change
• Low pressure alarm that comes and goes at idle
• Oil weeping from the sensor body or its thread
• Corroded or damp terminal at the sensor
• Reading that changes when the connector is touched

🛠️ Service Notes

• Confirm the real pressure with a mechanical gauge before acting on a low-pressure warning — replacing a sensor on a genuinely low reading is a good way to lose an engine
• This number replaces two older sensors, so an engine may have either one fitted; check the thread and connector against what comes off
• Seal the thread as the manual specifies and do not overtighten it into the housing
