Kia Cadenza YG: Engine Control System / Manifold Absolute Pressure Sensor (MAPS) Description and Operation
Kia Cadenza YG 2016-2021 Service Manual / Engine Control / Fuel System / Engine Control System / Manifold Absolute Pressure Sensor (MAPS) Description and Operation
| Description |
Manifold Absolute Pressure Sensor (MAPS) is a speed-density
type sensor and is installed on the surge tank. It senses absolute
pressure of the surge tank and transfers the analog signal proportional
to the pressure to the ECM.
By using this signal, the ECM calculates the intake air quantity and engine speed.
The MAPS consists of a piezo-electric element and a hybrid IC
amplifying the element output signal. The element is silicon diaphragm
type and adapts pressure sensitive variable resistor effect of
semi-conductor.
Because 100% vacuum and the manifold pressure apply to both
sides of the sensor respectively, this sensor can output analog signal
by using the silicon variation proportional to pressure change.
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the IATS connector. 3. Measure resistance between the IATS terminals 3 and 4. 4.
Specification Pressure [kPa (kgf/cm², psi)]Output Voltage (V)20.0 (0.20, 2.90)0.7946.66 (0.47, 6.77)1.84101.32 (1.03, 14.7)4.0
