Kia Niro 2017 (DE HEV) Service Manual / Engine Control/Fuel System / Engine Control System / Manifold Absolute Pressure Sensor (MAPS) Repair procedures

Inspection

1.	Connect the KDS/GDS on the Data Link Connector (DLC).

Measure the output voltage of the MAPS during idle with IG ON.

Pressure [kPa (kgf/cm², psi)]	Output Voltage (V) [Vref = 5V]
20.0 (0.20, 2.9)	0.79
46.7 (0.47, 6.77)	1.84
101.3 (1.03, 14.7)	4.0

Removal

1.	Switch "OFF" the ignition and disconnect the negative (-) battery terminal.

2.	Disconnect the manifold absolute pressure sensor connector (A).

Remove the sensor (B) after loosening the mounting bolt from the intake manifold.

Manifold absolute pressure sensor mounting bolt:

9.8 - 11.8 N·m (1.0 - 1.2 kgf·m, 7.2 - 8.7 lb·ft)

Installation

•	Install the component to the specified torque.

•	Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.

•	Insert the sensor in the installation hole and be careful not to damage it.

1.	Install in the reverse order of removal.
