DPP GM Style 3 Bar Map Sensor can measure up to 44.1psi, which translates to 29.7psi boost from a Turbo/supercharger. Supplied complete with 3 Pin Plug
These are top quality 100% tested electronic sensors manufactured to the highest quality standards.
The ECU uses the manifold absolute pressure (MAP) sensor to determine the absolute pressure (not the relative to atmospheric pressure) of the air inside the intake manifold and the atmosphere (barometric pressure).
Pinouts are:
Wiring Pinout
Pin A = Ground
Pin B = Sensor output
Pin C = +5VDC
Linear Output
0.3V = 20kpa
4.9V = 300kpa
