Bosch 0261230350 Boost Pressure Sensor MAP Sensor

The Bosch 0 261 230 350 is an OE-quality Manifold Absolute Pressure (MAP) / Boost Pressure Sensor engineered for turbocharged Mercedes-Benz engines. As a world-leading OEM supplier to Mercedes-Benz, Bosch manufactures this sensor to the same exacting standards as the original equipment installed at the factory. The sensor continuously monitors intake manifold pressure and delivers precise voltage signals to the engine control unit (ECU), enabling optimal fuel delivery, ignition timing, and turbocharger boost control.

Key Features:

• Direct OEM replacement — manufactured by Bosch, the original equipment supplier for Mercedes-Benz
• Measures manifold absolute pressure to support accurate air/fuel ratio management
• Provides real-time boost pressure feedback to the ECU for turbocharger control
• Precision-calibrated sensing element for stable, repeatable output signal
• Plug-and-play fitment with factory wiring harness connector — no modifications required
• Resistant to heat, vibration, and engine bay contaminants
• Helps restore proper engine performance, fuel economy, and emissions compliance

A failing boost pressure sensor can trigger check engine lights, turbocharger overboost or underboost conditions, rough idle, hesitation under acceleration, and reduced fuel efficiency. Replacing it with a genuine Bosch unit ensures the ECU receives the accurate pressure data it needs to maintain peak engine performance.
