Bosch 4000 PSI Fluid Pressure and Temperature Sensor

Overview

The Bosch 4000 PSI Fluid Pressure and Temperature Sensor delivers precision monitoring for high-performance fuel systems, oil circuits, and turbocharger installations. This dual-function sensor combines accurate pressure readings up to 4000 PSI with integrated temperature measurement, giving your Haltech ECU the critical data needed for optimal fuel delivery, oil pressure protection, and forced induction tuning.

Why You Need This

High-pressure fuel systems in performance builds demand accurate monitoring to prevent catastrophic failures. Whether you're running a direct injection conversion on a 2JZ, monitoring oil pressure in a high-boost RB26 build, or tracking fuel rail pressure in an E85 LS swap, this Bosch sensor provides the reliability your engine depends on. The integrated temperature monitoring adds crucial context — fuel temperature affects density and injection timing, whilst oil temperature data helps protect bearings under sustained high loads.

Many builders make the mistake of using cheap aftermarket pressure sensors that drift under heat or fail completely when exposed to ethanol fuels. Bosch OE sensors are designed for the harsh realities of modern performance applications — they maintain accuracy across temperature ranges, resist fuel contamination, and provide the stable signal your Haltech ECU needs for precise fuel and ignition mapping. The 4000 PSI rating handles even the most demanding applications, from nitrous-fed drag motors to high-pressure direct injection systems.

ECU & System Compatibility

Compatible with the full Haltech Elite and Nexus range, including Elite 550/750/1000/1500/2000/2500 and Nexus R3/R5 ECUs. The sensor connects directly to analogue inputs, with temperature monitoring via thermistor inputs. Contact our team to confirm optimal wiring and calibration for your specific ECU and application.
