MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR
The powertrain control module (PCM) supplies 5
volts direct current to the MAP sensor. The MAP
mospheric air pressure from the MAP sensor volt-
sensor converts intake manifold pressure into volt-
age. While the engine operates, the PCM deter-
age. The PCM monitors the MAP sensor output
mines intake manifold pressure from the MAP sen-
voltage. As vacuum increases, MAP sensor voltage
sor voltage. Based on MAP sensor voltage and
decreases proportionately. Also, as vacuum de-
inputs from other sensors, the PCM adjusts spark
advance and the air/fuel mixture.
creases, MAP sensor voltage increases proportion-
ately.
At wide-open-throttle and during cranking, before
the engine starts running, the PCM determines at-
The MAP sensor mounts to the intake manifold.
INTAKE AIR TEMPERATURE SENSOR
The intake air temperature sensor measures the
temperature of the air as it enters the engine. The
sensor supplies one of the inputs the PCM uses
to determine injector pulse width and spark advance.
