MAP - GM 3 Bar MAP Sensor

  Add to Wish List  


MAP - GM 3 Bar MAP Sensor part# GM3bar-map


Standard GM style 3-bar MAP Sensor (Manifold Absolute Pressure Sensor), compatible with all flavors of the MegaSquirt EMS as well as the MicroSquirt EMS. We've changed suppliers - these are assembled in the USA, unlike the current Delphi production.

Calibration is linear with 1.1 kPa at 0 volts and 315.5 kPa at 5 volts.

Note this is just for the sensor, the wiring harness connector is sold separately as we give you a choice of a ready-to-crimp connector , or a pre-crimped pigtail . (Click the previous linked text for more info)

The new USA-assembled sensor uses a universal keying that is compatible with pigtails for 1, 2, and 3 bar MAP sensors. Older sensors used a specific keying:

Again, connector is shown here just to illustrate the proper keying. The wiring harness connector is sold separately as we give you a choice of a ready-to-crimp connector, or a pre-crimped pigtail. (Click the previous linked text for more info)
