• Robust Construction: Engineered to withstand high temperatures, vibration, and harsh engine bay environments.
• Wide Operating Range: Capable of measuring pressures from vacuum up to full boost, making it suitable for naturally aspirated and turbocharged engines alike.

Vehicle Compatibility Overview

The sensor is engineered to fit a broad spectrum of models across several manufacturers. Below are representative vehicle families that use the 0261230254 MAP sensor:

• Mini Cooper (R56, R57, R58, R60) – 1.6‑liter petrol engines from 2010 to 2016.
• Mini Countryman & Mini Convertible – 1.6‑liter engines from 2010 to 2016.
• Citroën C3, C4, DS3, and DS4 – 1.4‑ or 1.6‑liter petrol variants from 2009 to 2017.
• Peugeot 207, 308, 3008, and Partner – 1.4‑ or 1.6‑liter engines spanning 2008–2017.
• Other European brands such as Citroën C3 Picasso, DS3 VTi, and Peugeot 208 also support this sensor model.

Installation & Integration Tips

1. Disconnect the battery: Prior to any work, ensure the vehicle’s electrical system is safely isolated.
2. Locate the MAP sensor: It is typically mounted on or near the intake manifold, connected via a short vacuum hose.
3. Remove the old sensor: Unscrew the mounting bolt and gently detach the wiring harness. Be careful not to damage the connector pins.
4. Install the new Bosch sensor: Align the 4‑pin connector, secure it with the mounting bolt, and ensure a tight seal on the vacuum hose.
5. Reconnect the battery and test: Start the engine and verify that the vehicle’s diagnostic system recognizes the new sensor without error codes.
