Bosch 0261230011 Pressure/Temperat Sensor

BOSCH 0261230011 Pressure/Temperature Sensor

The BOSCH 0261230011 is a high‑performance intake manifold pressure (MAP) sensor that also measures the temperature of the air entering an internal combustion engine. Designed for modern gasoline and diesel engines, it delivers precise data to the engine control unit (ECU), enabling optimal fuel injection, ignition timing, and overall power delivery.

Key Functionalities

• Dual‑parameter measurement: Simultaneously captures pressure within the intake manifold and the temperature of the incoming air.
• Wide operating range: Handles pressures from vacuum to high boost levels, making it suitable for naturally aspirated engines as well as turbocharged or supercharged units.
• High accuracy and stability: Bosch’s proprietary sensor technology ensures minimal drift over time, maintaining reliable engine performance across a wide temperature spectrum.
• Compact design: The small footprint allows easy installation in tight engine bay spaces without compromising airflow or cooling.

Technical Specifications

Installation Overview

Installing the BOSCH 0261230011 involves a few straightforward steps:

1. Remove the old sensor: Disconnect the electrical connector, unscrew or unclip the existing MAP/temperature sensor from the intake manifold.
2. Prepare the mounting surface: Clean the thread area to ensure a proper seal and avoid contamination.
3. Attach the new sensor: Screw in the Bosch sensor, tightening it to the manufacturer’s torque specification (typically 5–7 Nm).
4. Reconnect wiring: Plug the connector into the ECU or dedicated MAP/temperature input port.
5. Verify operation: Use an OBD‑II scanner or diagnostic tool to confirm that pressure and temperature readings are within expected ranges.

Compatibility Highlights

The sensor is engineered for a broad range of vehicles, including but not limited to:

• Volkswagen & Seat models: Golf, Polo, Caddy, Arosa, and many others.
• Audi and Skoda platforms: Various engine families that require MAP input.
• BYD, Changan, Chang’an, Great Wall, Hafei, and other OEMs: Engines with intake manifolds that support a MAP sensor.

Its standardized connector and signal output make it a drop‑in replacement for many factory sensors across these brands.

Benefits to Engine Management

• Enhanced fuel efficiency: Accurate pressure data allows the ECU to calculate the exact amount of fuel needed, reducing waste.
• Improved throttle response: Real‑time temperature readings help adjust air–fuel ratios for smoother acceleration.
• Reduced emissions: Precise sensor input leads to cleaner combustion and lower exhaust pollutants.
• Longevity: Bosch’s robust construction resists corrosion, vibration, and thermal cycling, extending service life.

Maintenance Tips

While the sensor is designed for long‑term reliability, periodic checks can preempt issues:

• Inspect the connector for corrosion or loose pins; clean with contact cleaner if necessary.
• Verify that the mounting surface remains free of oil or debris to maintain a proper seal.
• Use diagnostic software after any major engine work (e.g., turbocharger replacement) to ensure sensor readings remain accurate.

Conclusion

The BOSCH 0261230011 Pressure/Temperature Sensor is a critical component for modern engines that demand precise control over air intake and combustion. Its dual‑parameter capability, wide compatibility range, and proven durability make it an indispensable part of any vehicle’s engine management system.
