Mercedes-Benz W205 Air Pressure Sensor | C-Class MAP & Boost Pressure Sensor Spares

Description

Restore precise fuel metering, crisp turbocharger responsiveness, and optimal combustion safety to your engine with this premium Mercedes-Benz W205 Air Pressure Sensor (Manifold Absolute Pressure / Boost Pressure Sensor). Specifically sourced and verified for the fourth-generation C-Class (W205 platform), this high-precision electronic sensor is the definitive replacement for vehicles experiencing engine surging, sudden power drop-offs, severe turbo lag, or persistent electronic fault codes related to intake air pressure calculations.

The Air Pressure Sensor ($MAP$ or Boost Sensor) is a critical data input hub for your vehicle’s Engine Control Unit ($ECU$). Positioned along the intake tract or manifold, it continuously monitors the density and pressure of the air entering the combustion chambers, allowing the engine management system to calculate the exact volume of fuel required and safely regulate turbocharger boost delivery. Because modern Mercedes-Benz engines operate on tight air-fuel tolerances, a failing sensor throws the entire system out of balance. Over time, the sensitive internal silicon crystal element becomes coated in thick carbon buildup and oily blow-by vapors from the crankcase ventilation ($PCV$) system. This leads to delayed or inaccurate voltage signals, causing the $ECU$ to over-fuel or under-fuel the engine. Typical symptoms include a rough idle, heavy hesitation under load, poor fuel economy, or the vehicle dropping into a protective “limp home” mode with diagnostic codes like $P0106$ or $P0234$. Replacing the faulty sensor instantly stabilizes engine performance.

Manufactured with premium solid-state electronics and high-durability composite housings, this sensor is built to withstand extreme vibration and intense under-hood thermal cycling. It features an exact factory pin configuration that clips directly into your original W205 wiring loom harness, ensuring a clean plug-and-play installation without requiring wiring modifications. Trust TP German Auto Spares for fully verified, workshop-tested automotive electronics, engine management sensors, and fuel system spares that keep your Mercedes-Benz running flawlessly.
