Bosch 0261230147 Pressure/Temperat Sensor

Product Overview

The Bosch 0261230147 Pressure/Temperature Sensor is a precision-engineered unit designed to monitor both oil pressure and temperature in high-performance engines. It delivers reliable data for engine control units, ensuring optimal operation and protection of critical components.

Key Functionalities

• Dual Measurement Capability: Simultaneously measures oil pressure and oil temperature, providing comprehensive insight into the lubrication system.
• High Accuracy: Engineered to maintain tolerance within ±2% across the full operating range, guaranteeing precise feedback for engine management systems.
• Robust Construction: Constructed from high-grade materials that resist corrosion and thermal degradation, extending service life even under demanding conditions.

Technical Specifications

Installation Guidelines

The sensor is designed for straightforward integration into existing engine management architectures. Follow these steps to ensure optimal performance:

1. Remove the Existing Sensor: Disconnect the electrical connector and unscrew the mounting bolts.
2. Prepare the Mounting Surface: Clean the area with a solvent-free cleaner, ensuring no residue remains that could affect sealing.
3. Position the New Unit: Align the sensor’s mounting flange with the engine block or oil pan. Apply a thin layer of high-temperature gasket sealant if required by the vehicle manufacturer.
4. Screw Securely: Tighten bolts to the specified torque (typically 15–20 Nm) using a calibrated torque wrench.
5. Reconnect Wiring: Attach the 4‑wire connector, verifying correct pin alignment. Inspect for any loose contacts or damaged insulation.
6. Verify Functionality: Use an engine diagnostic tool to read sensor outputs and confirm they fall within expected ranges during idle and under load.

Compatibility Overview

The Bosch 0261230147 is engineered for use in a variety of high-performance vehicles, particularly those from the Porsche lineup. It matches the specifications required by models such as:

• Porsche 911 (997) – both coupe and convertible variants.
• Porsche Boxster and Cayman series (987/987).
• Porsche Cayenne (9PA) – including turbocharged engines up to 4.8 L.

Its universal 4‑wire, 0–5 V output allows seamless integration with most modern engine control units that support dual oil pressure and temperature inputs.

Performance Benefits

• Enhanced Engine Protection: By continuously monitoring oil pressure and temperature, the sensor enables early detection of potential lubrication failures, preventing costly damage to bearings and pistons.
• Improved Fuel Efficiency: Accurate temperature data allows the engine control unit to optimize combustion timing, reducing fuel consumption without compromising performance.
• Reduced Maintenance Intervals: Reliable sensor readings help technicians diagnose issues more quickly, leading to fewer unnecessary oil changes and filter replacements.

Quality Assurance & Compliance

The Bosch 0261230147 undergoes rigorous testing in accordance with automotive industry standards. It complies with:

• ISO/TS 16949: Automotive quality management system.
• SAE J1349: Standard for oil pressure sensors.
• DIN 70020: European standard for automotive sensor performance.

Maintenance & Troubleshooting

While the sensor is designed to be maintenance-free, periodic checks can ensure continued reliability:

• Visual Inspection: Look for cracks, corrosion, or loose connections.
• Signal Verification: Use a multimeter or diagnostic scanner to confirm voltage output matches expected values at idle and under load.
• Replace if Faulty: If readings are inconsistent or the sensor fails to respond, replace with an identical Bosch unit to maintain system integrity.

Conclusion

The Bosch 0261230147 Pressure/Temperature Sensor delivers precise, reliable monitoring of oil pressure and temperature in high-performance engines. Its robust construction, accurate measurement range, and compatibility with a wide array of Porsche models make it an essential component for maintaining engine health and performance.
