Power Transistor: Description and Operation
IGNITION SIGNAL (DTC: P1320)
Ignition Coil & Power Transistor (Built Into Distributor)
The ignition coil is a small molded type. The ignition signal from the Engine Control Module (ECM) is sent to the power transistor. The power
transistor switches on and off the ignition coil primary circuit. As the primary circuit is turned on and off, the proper high voltage is induced in the
coil secondary circuit.
