Operation Section 1 ± 23 (3) Manifold Absolute Pressure (MAP) sensor ‡ The construction and operational characteristics of the MAP sensor equipped with the J05D/J08E engines are identical to the conventional sensor. The MAP sensor uses the "Piezoelectric Resistance Effect" to detect air pressure inside the intake manifold. Under the Piezoelectric Resistance Effect, changes in electrical resistance accompany changes in voltage applied to the silicon element inside the sensor. )\XIVREP:MI[(MEKVEQ" 1SHIP 1SHIP :G 4 & +2( :G 4 & +2( 86-1 1SHIP 1SHIP 4VIWWYVI'LEVEGXIVMWXMGW" 3YXTYX:EPXEKI: 3YXTYX:EPXEKI:
