Galant VR4 AWD L4-1997cc 2.0L DOHC Turbo (1992)
Component Overview
LOCATION
The power transistor is located on the intake manifold.
OPERATION
The ECU controls ignition timing through the power transistor. The power transistor is a type of switch that allows a very low Voltage (from the ECU) to
control a larger amount of Voltage (negative side of coil).
It is actually two power transistors combined into one unit, controlling each circuit of the dual ignition coil. During engine cranking, the ignition timing
is fixed at 5°BTDC.
