3859020 — Inlet Pressure Sensor 3859020 3858987 For Volvo Engine Gi Gxi

This is an inlet pressure sensor, also known as a manifold absolute pressure (MAP) sensor, which measures the air pressure within the intake manifold to help the engine control unit (ECU) optimize fuel delivery and ignition timing. It is built to meet precise OEM standards for accuracy and reliability, unlike a faulty sensor that provides incorrect readings. Observable symptoms of a failing sensor include a check engine light illumination, rough idling, poor acceleration, and decreased fuel economy.

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

Illumination of the check engine light accompanied by noticeable engine performance issues like rough idling or hesitation during acceleration are the first signs of a faulty inlet pressure sensor. If left unaddressed, the ECU may operate with incorrect air-fuel mixture data, leading to increased emissions and potential long-term engine component stress.

Installation Tip

Ensure the electrical connector is clean and securely seated before plugging it into the new sensor. Avoid applying excessive force when tightening the sensor into its port, as this can damage the threads.

Service Note

Inspect the intake manifold and vacuum lines for any leaks or damage when replacing the inlet pressure sensor.
