Circuit Description

Manifold Absolute Pressure (MAP) sensor measures changes in intake manifold pressure (vacuum). A low voltage signal, about 2 volts, is sent to PCM on signal circuit at closed throttle (high vacuum) idle. A high voltage signal, about 4 volts, is sent at wide open throttle (low vacuum).
