Key Features:

  • Pressure Range: 20 kPa to 250 kPa absolute
    – Equivalent to 2.9 PSI to 36.3 PSI absolute
    – Supports up to approximately 21 PSI of boost pressure (relative to atmospheric)

  • Supply Voltage: 5V ±0.25V

  • Output Voltage: 0.2V to 4.9V (typical)

  • Accuracy: ±1.5% (typical at 25°C)

  • Temperature Range: -40°C to +125°C

  • Response Time: <1 ms

  • Package Type: Small Outline Package (SOP)

  • Port Style: Single port, top-mounted vacuum fitting (for 3/16” ID hose)

Can this be used as an external MAP sensor?

  • We do not recommend this. To protect the sensor from vibration, you both solder its pins to a circuit board and bolt the pins to the same board. The pins are not intended to connect directly to a wiring harness.

What MegaSquirt units can I use this sensor with?

  • This one works with V2.2, V3.0, and V3.57 main boards, as well as the DIYPNP.  It does not fit the MSPNP Gen 2 or MSPNP Pro units, and we do not recommend it for systems with an external MAP sensor, as noted above.
