The Manifold Absolute Pressure (MAP) sensor reacts to absolute pressure
in the intake manifold. It provides an input voltage to the
Powertrain Control Module (PCM). As engine load changes, manifold
pressure varies. The change in manifold pressure causes MAP sensor
voltage to change. The change in MAP sensor voltage results in a
different input voltage to the PCM (computer). The input voltage
level supplies the PCM with information about ambient barometric
pressure during engine start-up and engine load while the engine is
running. The PCM uses this input along with inputs from other sensors
to adjust air-fuel ratio.
The MAP sensor is mounted on the frontward side of the engine throttle body.
The sensor is connected to the throttle body with a rubber L-shaped fitting.
The PCM is attached to the passenger inner fender side of the engine bay.
Good luck.
B.T.
