MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR FUNCTION [LF]

E5U014018210N01

• Detects intake air pressure in the intake manifold.

End Of Sie

MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR CONSTRUCTION/OPERATION [LF]

E5U014018210N02

• When pressure is applied to the piezoelectric 

element in the sensor, an electric potential 
difference occurs. Output voltage increases as 
the intake air pressure increases.

End Of Sie

BAROMETRIC PRESSURE (BARO) SENSOR FUNCTION [LF]

E5U014018211N01

• Detects the BARO.

End Of Sie

BAROMETRIC PRESSURE (BARO) SENSOR CONSTRUCTION/OPERATION [LF]

E5U014018211N02

• The BARO sensor is integrated in the PCM.

• The piezoelectric element is enclosed in the sensor and the electric potential difference changes as the BARO 

drops. The output voltage decreases as the BARO decreases.

KNOCK SENSOR (KS) FUNCTION [LF]

E5U014018920N01

• Detects abnormal combustion in the engine.

End Of Sie

KNOCK SENSOR (KS) CONSTRUCTION/OPERATION [LF]

E5U014018920N02

• Installed on the cylinder block (intake manifold 

side).

• Converts vibration from abnormal combustion in 

the engine to voltage using the piezoelectric effect 
in the semi-conductor and outputs it to the PCM.

• The piezoelectric effect is a phenomenon in which 

a difference in electric potential is produced on 
the surface of a piezoelectric element by the 
application of tensile load or pressure from a 
certain direction. Tensile load and pressure 
applied to the KS originates from engine vibration 
caused by abnormal combustion in the engine. 
The difference in electric potential, which results 
from the distortion by the vibration, is sent to the 
PCM as a knocking signal.
