Bosch 0261230058 Pressure Sensor

Overview of the Bosch 0261230058 Pressure Sensor

The Bosch 0261230058 is a high‑precision intake manifold pressure sensor (MAP sensor) designed to deliver accurate air‑pressure readings for modern internal combustion engines. It plays a critical role in engine management systems by providing real‑time data that enables optimal fuel injection, ignition timing, and overall performance.

Key Functional Characteristics

• Signal Type: Three‑pin output with a linear voltage signal ranging from 0.5 V to 4.5 V corresponding to pressure values of 0–1 bar.
• Operating Temperature: -40 °C to +125 °C, ensuring reliable performance in diverse climatic conditions.
• Mechanical Design: Compact, robust housing with a sealed inlet port that resists oil and coolant contamination.
• Electrical Interface: Standard automotive connector compatible with Bosch OEM wiring harnesses; no additional adapters required for most installations.

Primary Applications

The sensor is engineered for use in a wide range of passenger vehicles, including models from Citroën, Fiat, Lancia, Peugeot, and Renault. It is commonly found in engines ranging from 1.6 L to 3.0 L displacement, providing essential data for:

• Engine control units (ECUs) that regulate fuel‑air mixture.
• Turbocharged or supercharged powertrains where precise pressure measurement is vital for boost control.
• Hybrid and mild‑hybrid systems that rely on accurate manifold readings to balance electric and combustion power sources.

Installation Guidelines

1. Preparation: Disconnect the vehicle’s battery to prevent electrical hazards. Remove any protective covers around the intake manifold.
2. Sensor Removal: Unscrew the existing sensor using a suitable socket or wrench, taking care not to damage the inlet port.
3. Cleaning: Inspect and clean the inlet opening with a soft brush or compressed air. Ensure no debris remains that could affect pressure readings.
4. Mounting New Sensor: Align the sensor’s connector with the vehicle’s harness, then secure it in place using the original mounting hardware.
5. Verification: Reconnect the battery and use an OBD‑II scanner to confirm that the ECU registers a valid pressure signal. Adjust if necessary according to manufacturer specifications.
