Bosch 145 PSI Fluid Pressure and Temperature Sensor Thread: M10 x 1.0

Integrated Telemetry: Bosch 145 PSI Fluid Pressure & Temp Sensor

The Bosch 145 PSI Fluid Pressure and Temperature Sensor is a revolutionary all-in-one instrument designed for critical low-pressure systems. Capable of measuring pressures up to 145 PSI (10 Bar) and temperatures from -40°C to 140°C, this sensor is the professional standard for monitoring fuel rail pressure, engine oil pressure, and transmission health. By consolidating two essential data points into a single M10 x 1.0 threaded port, this sensor simplifies harness integration and reduces plumbing complexity in high-performance 2JZ, LS-swap, and RB26 builds. It is a vital component for enabling ECU safety strategies and detonation protection through pressure monitoring.

Engineering Principles: Dual Signal Logic

This Bosch sensor uses a high-precision silicon sensing element for pressure and a calibrated NTC thermistor for temperature. The Analogue-to-Digital interface allows your standalone ECU integration to receive a precise 0-5V pressure signal and a resistive temperature signal simultaneously. This is foundational for advanced engine management; the ECU can correlate oil pressure with oil temperature to identify mechanical wear or pump cavitation that a simple pressure switch would miss. Because it is a genuine Bosch unit, the calibration is incredibly stable, providing the deterministic feedback required for a robust fuel map calibration and protection map setup.

Operational Benefits: Compact System Integrity

One of the most significant advantages of this sensor is its ability to be installed in tight locations where two separate sensors would not fit. For builds utilizing closed-loop boost control, monitoring fuel pressure is mandatory; if the rail pressure drops relative to boost, the ECU can instantly trigger a safety limiter to prevent a lean-out event. The sensor includes an M10 x 1.0 to 1/8 NPT adaptor, making it compatible with almost all aftermarket fuel regulators and oil filter blocks. This versatility ensures that your harness integration remains clean and modular, with all critical fluid data centralized on your iC-7 Digital Display.

Installation and Critical Wiring Notes

Warning: Please take care when wiring this sensor as incorrect wiring will damage this sensor! The unit requires a regulated 5V supply and careful pin assignment for the pressure and temperature outputs. The kit includes the matching plug and pins for a professional, moisture-proof connection. For high-vibration applications, Haltech recommends remote mounting the sensor via a flexible hose (such as HT-039103) to prevent the sensing diaphragm from fracturing due to engine harmonics. This sensor is individually electronically tested before packaging to ensure laboratory-grade accuracy from day one.
