Bosch 0261230118 Pressure and Temperature Sensor

Bosch 0261230118 Pressure and Temperature Sensor

The Bosch 0261230118 is a high‑performance pressure and temperature sensor designed for automotive intake manifolds. It delivers precise MAP (Manifold Absolute Pressure) readings combined with ambient air temperature data, enabling the engine control unit to optimize fuel injection, ignition timing, and boost pressure management.

Key Functionalities

• Dual‑parameter sensing: Simultaneously measures intake manifold pressure and air temperature.
• Wide operating range: Accurate from vacuum to high boost pressures, suitable for naturally aspirated and turbocharged engines.
• Robust construction: Sealed housing resists oil, coolant, and combustion gases.
• Fast response time: Millisecond‑level signal delivery ensures real‑time engine control.

Electrical Characteristics

The sensor outputs a 4–20 mA current loop, a standard automotive interface that provides immunity to electrical noise over long wiring runs. The device operates on the vehicle’s 12 V or 24 V supply, with typical consumption below 50 mA.

Installation Compatibility

This unit is engineered for Mitsubishi Smart Forfour, Colt Lancer, and other models that use the Bosch 0 261 230 118 reference. It fits directly into the intake manifold’s pressure port, replacing OEM MAP sensors without modification.

Calibration and Tuning Benefits

• Accurate fuel mapping: Precise pressure data allows the ECU to calculate exact air mass flow.
• Enhanced throttle response: Real‑time temperature readings help adjust idle speed and acceleration curves.
• Improved emissions control: Correct sensor data reduces knock risk and ensures optimal combustion.

Durability Features

The sensor’s hermetic seal protects against moisture ingress, while its high‑temperature ceramic diaphragm withstands the harsh environment of the intake manifold. The rugged metal housing resists vibration and mechanical shock during operation.

Typical Applications

• Performance tuning: Enthusiasts use it to fine‑tune boost controllers and fuel maps.
• Diagnostic replacement: Mechanics replace faulty MAP sensors in vehicles that originally shipped with this Bosch model.
• Engine management upgrades: It is a common choice for aftermarket ECU setups requiring reliable pressure and temperature inputs.

Maintenance Tips

• Inspect the sensor connector for corrosion before installation.
• Use a calibrated pressure source to verify output during troubleshooting.
• Avoid exposing the sensor to oil or coolant; if contact occurs, clean with isopropyl alcohol and re‑seal.

Conclusion

The Bosch 0261230118 Pressure and Temperature Sensor delivers reliable, high‑accuracy data essential for modern engine management systems. Its dual‑parameter capability, robust construction, and compatibility with a wide range of Mitsubishi models make it an indispensable component for both OEM installations and aftermarket performance projects.
