Bosch MAP Sensor for Mercedes‑Benz & Maybach — 0261230189 Direct-Fit, OEM Accuracy

The BOSCH 0261230189 is a direct-fit Manifold Absolute Pressure (MAP) sensor engineered to deliver precise intake-air pressure readings and restore accurate engine management.

This Bosch MAP sensor measures the absolute pressure inside the intake manifold and supplies the engine control unit with the data needed for fuel and ignition adjustments. Built to Bosch's OEM-level standards, it uses improved chip technology and a corrosion-resistant coating for long-term stability in harsh intake environments. Whether you’re repairing or maintaining a compatible Mercedes‑Benz or Maybach, this sensor aims to match original specifications for fit, function, and durability.

How does this MAP sensor affect engine performance?

A MAP sensor helps the ECU calculate the correct air–fuel ratio by reporting intake pressure. When the sensor returns accurate values, the vehicle can optimize fuel delivery and ignition timing, improving driveability and reducing the chance of rough idling or hesitation.

• Precise pressure readings for consistent fuel trims and ignition advance
• Works with engine management to maintain smooth throttle response
• Designed to meet or exceed original equipment accuracy

What makes the BOSCH 0261230189 more durable than generic sensors?

Bosch engineered this MAP sensor with a robust housing and a protective coating that resists chemical exposure inside the intake manifold. Combined with modern chip design, these features reduce drift and failure risk over time compared with lower-cost alternatives.

• Chemical-resistant coating protects sensitive electronics from intake contaminants
• Sturdy mechanical construction resists vibration and thermal cycling
• Updated semiconductor technology for improved long-term stability

Is the BOSCH 0261230189 compatible with my vehicle?

This part fits a wide range of Mercedes‑Benz and Maybach models—covering sedans, SUVs, coupes, and performance AMG variants across multiple years. Always confirm fitment using your VIN or the vehicle compatibility checker before purchasing to ensure correct connector and calibration.

• Compatible with many Mercedes‑Benz models including C, E, S, SL, CLK, CLS, GL/GLS, G, ML, R, SLK, and AMG editions
• Includes coverage for select Maybach S-Class and Sprinter 2500/3500 applications
• Verify exact model years and engine options with the fitment tool or dealer parts list

How do I install or diagnose the MAP sensor if I suspect an issue?

Installation is typically straightforward: unplug the electrical connector, remove mounting fasteners, and swap the sensor. For diagnostics, check for fault codes related to MAP, compare live sensor voltage versus expected ranges, and inspect the connector and vacuum passages for contamination or leaks.

• Basic swap requires simple hand tools and access to the intake manifold sensor location
• Use an OBD-II scanner to read MAP-related trouble codes and live data
• Inspect wiring harness and intake path for damage, blockages, or oil contamination

Who this is for: The BOSCH 0261230189 MAP sensor is aimed at technicians, independent shops, and do-it-yourself owners maintaining Mercedes‑Benz and select Maybach vehicles who need a reliable, OEM-grade replacement. Choose this sensor if you want a part engineered by a leading supplier of engine-management components, with the goal of restoring accurate manifold pressure measurement and dependable driveability.
