Plug and Pins Only – Bosch 4000psi Fluid Pressure and Temperature Sensor

Specialized Termination: Bosch 4000psi Sensor Connector Kit

Modern engine management relies on combined sensors to reduce wiring complexity and improve data density. The Bosch 4000psi Fluid Pressure and Temperature Sensor (commonly used for oil and fuel pressure monitoring) utilizes a specific compact automotive connector. This Plug and Pins Only kit provides the correct mating connector housing, terminals, and seals to fabricate a professional harness for this specific sensor (Suits Haltech HT-010925). Using the correct connector is vital; generic substitutes often fail to seal correctly against the sensor body, leading to water ingress, corrosion, and sensor failure—a catastrophic scenario if the sensor is monitoring critical oil pressure.

Connector Architecture

This kit features a 4-way compact housing designed to mate perfectly with the Bosch combined sensor. The connector includes individual wire seals to ensure IP-rated weatherproofing. The terminals are designed for high-vibration environments, featuring a dual-spring contact design that maintains continuity even under the severe harmonics of a race engine. This connector carries four distinct signals: 5V Reference, Sensor Ground, Pressure Signal (Analog), and Temperature Signal (NTC). Ensuring a low-resistance connection on the ground and reference lines is critical for measurement accuracy.

Application Notes

This connector is specifically keyed and shaped for the Bosch combined pressure/temp sensor typically found in high-pressure fuel systems (GDI) and aftermarket performance fluid monitoring. It allows for the repair of damaged harnesses or the creation of new sub-harnesses without splicing pigtails. The included terminals require a proper open-barrel crimping tool for a secure mechanical bond.
