Manifold Pressure/Vacuum Sensor: Description and Operation
1998 Suzuki Esteem GLX Sedan Plus L4-1.6LSECTION Description and Operation
Manifold Absolute Pressure Sensor (MAP Sensor)
This sensor senses pressure change in the intake manifold and converts it into voltage change. It consists of a semi-conductor type pressure converting element which converts a pressure change into an electrical change and an integrated circuit which amplifies and corrects the electric change.
The ECM sends a 5-volt reference voltage to the pressure sensor. As the manifold pressure changes, the electrical resistance of the sensor also changes.
By monitoring the sensor output voltage, ECM knows the manifold pressure (intake air volume).
ECM uses the voltage signal from the pressure sensor as one of the signals to control various devices.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
