P259F Turbocharger \'A\' Boost Control Position At High Limit - General Information

Component Location





General Description

Turbo charger controlled by ECU is being applied recently. ECU calculates the optimized fuel ratio by measuring the accurate air mass from turbo charger.
If the boost pressure from intake manifold reaches target pressure value, ECU makes a part of exhaust gas bypass.
Concentrated mix gas makes much higher horse power in explosion cycle.

DTC Description

ECU shows this DTC when opening PWM of EWGA motor control is higher than +98% because of the fault of EWGA position.
* Closing PWM is controlled by (-) duty and opening PWM is (+) duty.
