Mercedes Sprinter Boost Pressure Sensor – Bosch | NCV3 3.0L OM642 | #0061539928 (2010–2018)

A failed boost pressure sensor on a Sprinter OM642 removes the ECU's primary feedback signal for turbocharger output — causing boost control errors, under-boost fault codes, and reduced performance that won't resolve until accurate pressure data is restored. This is the Bosch boost pressure sensor for NCV3 Sprinters equipped with the 3.0L OM642 diesel engine, a direct replacement that restores accurate boost monitoring and proper turbocharger control.

What This Part Does

The boost pressure sensor monitors charge air pressure in the intake system downstream of the turbocharger and reports that pressure to the ECU in real time. The ECU uses this data to verify that the variable geometry turbocharger is delivering commanded boost at each operating point, to regulate VGT vane position for optimal boost response, and to detect over-boost or under-boost conditions that require protective intervention. When the sensor fails or drifts, the ECU loses its boost feedback signal — causing the VGT system to operate in default mode, generating fault codes, and reducing performance.

Common Symptoms of a Failing Boost Pressure Sensor

• Check engine light with boost pressure sensor circuit or turbocharger performance fault codes
• Engine entering limp mode from boost system monitoring failure
• Under-boost or over-boost codes without a confirmed boost system leak
• Sluggish throttle response or flat power delivery under load
• Fault codes that return after clearing without other turbo system faults

When to Replace

Replace when confirmed faulty by scan tool with active boost pressure sensor fault codes, after ruling out boost leaks, VGT actuator, and vacuum supply as the primary fault.
