Atmospheric Pressure Sensor
Atmospheric pressure is monitored by the atmospheric pressure sensor. The sensor is located on the mounting for the ECM. A 5.0 ± 0.5 VDC supply voltage is provided by the ECM. The output of the atmospheric pressure sensor is a DC signal. The signal has a range of 0.2 volts to 4.8 volts. The ECM interprets the output voltage as atmospheric pressure.
