P010A MANIFOLD ABSOLUTE PRESSURE SENSOR

P010A MANIFOLD ABSOLUTE PRESSURE SENSOR

Description

INFOID:0000000005597971

The manifold absolute pressure (MAP) sensor is placed at intake
manifold collector. It detects intake manifold pressure and sends the
voltage signal to the ECM.
The sensor uses a silicon diaphragm which is sensitive to the
change in pressure. As the pressure increases, the voltage rises.

DTC Logic

INFOID:0000000005597979

DTC DETECTION LOGIC

NOTE:
If DTC P010A is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643. 
Refer to 

EC-965, "DTC Logic"

.

DTC CONFIRMATION PROCEDURE
