3-Bar MAP Sensor

The AMP EFI LDM-899003 is a 3-Bar Manifold Absolute Pressure (MAP) sensor designed to accurately monitor manifold pressure across a wide range of boost levels. This sensor is ideal for performance vehicles, supporting both high-boost applications and more modest naturally aspirated or lightly boosted setups with its versatile 3-bar and 1-to-2 bar range. Constructed with a durable build, the sensor features a 1/8″ NPT screw-in design, which ensures a superior seal and greater longevity compared to standard nipple-style sensors. It requires a 5V reference voltage and outputs a signal ranging from 0.5V to 4.5V, providing precise data for engine management systems. The included 15-foot cable, equipped with a 90° boot, offers flexibility for mounting in tight or custom engine bays, simplifying installation. The wiring is straightforward: Red for 5V Vref, Black for Sensor Ground, and Yellow for the Signal Output to the ECU. The product is available as the sensor only or as a combo package that includes the sensor with the 15ft cable and 90° boot, offering convenience for various installation needs.
