Component Description
IGNITION COIL & POWER TRANSISTOR
The ignition signal from the ECM is sent to and amplified by the power transistor. The power transistor turns
on and off the ignition coil primary circuit. This on-off operation induces the proper high voltage in the coil
secondary circuit.
On Board Diagnosis Logic
Malfunction is detected when the ignition signal in the primary circuit
is not sent to ECM during engine cranking or running.
Possible Cause
I Harness or connectors (The ignition primary circuit is open or
shorted.)
I Power transistor unit built into ignition coil
I Condenser
I Crankshaft position sensor (REF)
I Crankshaft position sensor (REF) circuit
DTC Confirmation Procedure
NOTE:
I If “DTC Confirmation Procedure” has been previously
conducted, always turn ignition switch “OFF” and wait at least
10 seconds before conducting the next test.
I If DTC P1320 is displayed with DTC P0335, P0340, P1335
or P1336, perform trouble diagnosis for DTC P0335,
P0340, P1335 or P1336 first. Refer to EC-391, EC-399,
EC-596 or EC-602.
