20706889 — Boost Pressure Sensor 20706889 For Volvo Penta Engine D12A Truck Fh Fh12 Fm12 Fm9

This boost pressure sensor monitors the air intake manifold pressure, providing critical data to the engine control unit (ECU) for optimal fuel and ignition timing. It ensures accurate air-fuel mixture by detecting deviations from expected boost levels, unlike a worn sensor that may provide inaccurate readings. Operators may notice a loss of engine power, increased fuel consumption, or a check engine light with diagnostic trouble codes related to boost pressure when this sensor fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a failing boost pressure sensor is often a noticeable reduction in engine power or responsiveness. If ignored, the engine may begin to run inefficiently, leading to increased fuel consumption and potential stalling. Continued operation with a faulty sensor risks uneven engine operation and potential damage to internal components due to improper air-fuel mixtures.

Installation Tip

Clean the sensor port thoroughly before installation to ensure a proper seal and accurate readings. Avoid overtightening the sensor, as this can damage the threads or the sensor housing.

Service Note

Inspect the engine's air intake system for leaks, blockages, and the condition of intercooler hoses when replacing the boost pressure sensor.
