Show original supplier description
The AMP EFI LDM 0-150 PSI Pressure Sensor offers precise pressure monitoring for critical engine systems, making it ideal for measuring fuel, oil, or boost pressures. Designed for compatibility with a wide range of aftermarket engine management systems such as MegaSquirt and MS3Pro, this sensor delivers a consistent and linear 0-5V output signal that integrates smoothly with your ECU. Its robust construction is built to withstand harsh environmental conditions, ensuring reliability and longevity. Installation is straightforward thanks to its 1/8” NPT screw-in design. The sensor boasts high accuracy, with a tolerance of ±1% of the full scale, and operates within a working temperature range of -40°F to 257°F (-40°C to 125°C). Depending on the firmware version of your ECU, specific configuration settings may be required: for Firmware 1.6, select the “Linear .5v-4.5v” option for a pressure range of 0 to 150 PSI. For Firmware 1.5 or older, select the “Linear” option, which corresponds to a pressure range of -18.75 PSI to 168.75 PSI. The sensor features a simple wiring scheme: Red connects to 5V Vref, Black to Sensor Ground, and Yellow to the Signal Output to your ECU. Customers can purchase the sensor individually or with an optional 15ft cable that includes a 90° boot.
