Bosch 0261230236 Pressure and Temperature Sensor

Bosch 0261230236 Pressure and Temperature Sensor

The Bosch 0261230236 is a high‑performance pressure and temperature sensor designed for modern fuel injection systems. It delivers precise readings of manifold absolute pressure (MAP) and intake air temperature, enabling the engine control unit to optimize fuel delivery, ignition timing, and overall combustion efficiency.

Key Functionalities

• Dual‑parameter measurement: Simultaneously senses both pressure and temperature within the intake manifold.
• Wide operating range: Handles pressures from vacuum to high boost levels, while maintaining accurate temperature readings across typical automotive operating temperatures.
• High reliability: Built with Bosch’s proven sensor technology, featuring robust sealing and corrosion‑resistant materials for long service life.
• Low power consumption: Designed to operate efficiently within the vehicle’s electrical system, minimizing load on the battery and alternator.

Technical Specifications

Installation Overview

The sensor is engineered for straightforward replacement. Remove the existing MAP sensor by disconnecting the electrical connector and unscrewing the mounting bolt. Align the new Bosch 0261230236 with the intake manifold’s sensor port, secure it with the provided torque specification (typically 10 Nm), and reconnect the wiring harness. After installation, perform a diagnostic check to confirm correct pressure and temperature readings.

Performance Benefits

• Enhanced Fuel Efficiency: Accurate MAP data allows the engine control unit to calculate optimal fuel injection timing, reducing excess fuel consumption.
• Improved Emissions Control: Precise pressure and temperature measurements help maintain stoichiometric air‑fuel ratios, lowering harmful exhaust emissions.
• Better Engine Response: Real‑time sensor data enables quicker throttle response and smoother acceleration.
• Reliability Under High Load: The robust design withstands high boost pressures common in turbocharged engines without signal drift.

Maintenance Tips

Although the sensor is designed for longevity, regular checks can preempt issues:

1. Inspect the wiring harness for fraying or corrosion.
2. Verify that the mounting surface remains clean and free of oil residue.
3. Use a diagnostic scan tool to monitor MAP sensor output during idle and acceleration; sudden spikes may indicate failure.

Compatibility Summary

The Bosch 0261230236 is specifically tailored for:

• Volvo C30 (2004‑2012)
• Volvo C70 Mk2 (2006‑2009)
• Volvo S40 II (2004‑2010)
• Volvo V50 (2004‑2012)

Its design aligns with OEM specifications, ensuring seamless integration into the vehicle’s engine management system.

Conclusion

The Bosch 0261230236 Pressure and Temperature Sensor exemplifies precision engineering for automotive fuel systems. By delivering reliable MAP data across a wide range of operating conditions, it supports optimal engine performance, fuel economy, and emissions compliance. Whether restoring an older Volvo or maintaining a high‑performance vehicle, this sensor is a critical component that keeps the heart of the engine running smoothly.
