Bosch 0261230302 Pressure Sensor – Precision in Every Pulse

The Bosch 0261230302 pressure sensor is a high‑performance component engineered to deliver accurate and reliable measurements of intake manifold or boost pressure across a wide range of automotive applications. Designed with Bosch’s renowned engineering standards, this sensor plays a critical role in engine management systems by providing real‑time data that enables optimal fuel delivery, ignition timing, and overall vehicle performance.

Key Functionalities

• Intake Manifold Pressure (MAP) Measurement: Captures the absolute pressure within the intake manifold to inform engine control units (ECUs) for precise air‑fuel mixture calculations.
• Boost Pressure Sensing: Measures the pressure generated by turbochargers or superchargers, allowing the ECU to regulate boost levels and protect engine components from over‑boost conditions.
• Wide Operating Range: Handles pressures from vacuum (negative) up to high positive values typical of forced induction systems, ensuring versatility across naturally aspirated and turbocharged engines.
• Fast Response Time: Delivers rapid signal changes, essential for dynamic engine control during acceleration, deceleration, and transient load conditions.

Technical Specifications

Installation & Compatibility

The Bosch 0261230302 sensor is engineered to fit a broad spectrum of vehicle platforms, including but not limited to:

• European Brands: Opel, Fiat, Chevrolet, Alfa Romeo, Vauxhall, Peugeot, Citroën, and many others.
• American & Asian Models: Includes certain models from Ford, Dodge, and Hyundai where the intake manifold geometry matches Bosch’s specifications.
• Performance Variants: Turbocharged engines such as the Alfa Romeo Giulietta T‑Jet, Fiat Bravo II, and various Vauxhall Astra turbo models benefit from the sensor’s high‑accuracy boost measurement.

Installation typically involves removing the existing pressure sensor or intake manifold cover, cleaning the mounting surface, aligning the sensor with the threaded hole, and securing it with a torque wrench to the manufacturer’s recommended setting. A proper seal ensures no air leaks that could compromise pressure readings.
