20553463 Sensor | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta sensor is an OEM service component used in the Charge-Air Pressure / Temperature and Air-Filter Monitoring Sensor. It is manufactured to the original Volvo Penta dimensional, material and interface requirements for the documented Volvo Penta D5A/D7C industrial diesel application. Technical identification: Combined charge-air pressure/temperature sensor used in the intake-monitoring circuit; documented service-temperature range approximately -40°C to +120°C. In service, it measures the specified engine speed, position, pressure or temperature condition and sends the corresponding signal to the instrument or engine-control system. Selection must be confirmed by OEM part number 20553463, the exact model/product number, serial number and installed assembly configuration.

⚙️ Key Features

• Genuine Volvo Penta OEM sensor
• OEM part number 20553463
• Technical distinction: Combined charge-air pressure/temperature sensor used in the intake-monitoring circuit; documented service-temperature range approximately -40°C to +120°C
• Inspect the connector and target/port, install to the specified depth and torque, then verify live-data response and stored fault codes.

🔌 Function

Measures the specified engine speed, position, pressure or temperature condition and sends the corresponding signal to the instrument or engine-control system. Inspect the connector and target/port, install to the specified depth and torque, then verify live-data response and stored fault codes.

⚠️ Common Signs of Failure

• Fault codes, alarms or an implausible live-data/instrument reading
• Intermittent signal loss caused by vibration, heat or connector movement
• Poor starting, derating or unstable engine control
• Open circuit, short circuit or out-of-range resistance/voltage
• Corroded terminals, damaged wiring or a cracked sensor body

🛠️ Service Notes

• Note how the sensor sits and how its lead is routed before removing it, and support the harness so refitting does not leave the cable strained or rubbing
• Turn the sensor with a spanner on its hex only — never lever or twist it by the connector body or the wiring, which breaks the internal joint even when the sensor looks undamaged
• Renew the O-ring or sealing washer where one is fitted, and do not add thread sealant unless the manual for your engine specifies it; sealant on the threads can break the earth path of a sensor that earths through its body
• Tighten to the figure in the workshop manual for your engine — overtightening distorts the housing and shifts or destroys the sensing element
• Make sure the connector is clean, dry and fully latched home and check the pins for corrosion and spread — a poor connector accounts for a great many faults blamed on the sensor — then run the engine and confirm the reading or warning lamp behaves sensibly before returning the boat to service
