Corvette Manifold Absolute Pressure Sensor and Tool 1984-1995

Corvette engine performance depends heavily upon the manifold absolute pressure sensor which measures the variances in intake manifold pressures. This information is fed to the ECM, which uses it to adapt fuel mixture to different driving conditions. It even adapts to different altitudes. This Corvette Manifold Absolute Pressure Sensor Test Tool allows you to test the function of this sensor with a digital voltmeter. Instructions included.
