Oil Pressure Sensor
This page provides detailed information about the FuelTech 0-150 PSI Oil Pressure Sensor used in the Honda RC51 custom ECU build, including its specifications, connector details, wiring, and visual references.
FuelTech 0-150 PSI Oil Pressure Sensor Overview
While an oil pressure sensor is not required for ECU operation, it is highly recommended for monitoring engine health and ensuring safe operation. The Honda RC51’s oem setup use a pressure switch not a sensor, so it doesn't actually read pressure. Adding an oil pressure sensor, such as the FuelTech 0-150 PSI sensor, is straightforward and provides critical real-time data for monitoring oil pressure. In this example, I used a FuelTech 0-150 PSI sensor (Part #5005100020-BLK), but any oil-compatible pressure sensor is acceptable, provided the input is correctly configured in FT Manager. This is the same sensor as the Fuel Pressure Sensor.
FuelTech 0-150 PSI Oil Pressure Sensor Specifications
The FuelTech PS-150 Pressure Sensor (Part #5005100020-BLK) is designed for accurate and reliable pressure readings in the range of 0-150 PSI. It is suitable for monitoring oil, fuel, or wastegate pressure, making it a versatile component for performance-driven setups.
Connector Data
The FuelTech PS-150 Oil Pressure Sensor uses a 3-pin Delphi connector (Part #12065287) for secure and reliable data transmission to the engine management system. Below are the details for the connector kit found on Fueltech's website:

Mounting the Pressure Sensor
To mount the PS-150 oil pressure sensor in place of the stock oil pressure switch, it is critical to note that the PS-150 uses 1/8"-27 NPT threads, while the stock switch has 1/8" BSPT threads with 28 TPI and a slightly smaller major diameter (0.383" vs. 0.405"). Due to differences in thread angle (55° for BSPT vs. 60° for NPT) and pitch, these threads are incompatible, requiring an adapter. A 1/8 BSPT to 1/8" NPT female adapter, e asily found on Amazon or eBay, allows the PS-150 sensor to be securely installed in the same location as the oil pressure switch.
ECU Setup
ECU configuration for the FuelTech 0-150 PSI sensor is very straightforward and identical to the Fuel Pressure Sensor setup. Follow the steps below and select the predefined sensor configuration.
- Open FT Manager.
- Navigate to Sensors and Calibration.
- Click on the Inputs tab.
- Locate your Oil Pressure input field.
- Select the correct default sensor parameter.
Wiring Diagram
The FuelTech PS-150 Oil Pressure Sensor uses a 3-pin connector with the following pinout: Pin A - Ground, Pin B - 5V, Pin C - Signal. Wiring is straightforward and can be connected to any available white input on the ECU. Refer to the FuelTech manuals for additional details if needed.
