what does obd code p1320 mean?

coil issue. here is the description. 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 Harness or connectors (The ignition primary circuit is open or shorted.) Power transistor unit built into ignition coil Condenser Crankshaft position sensor (REF) Crankshaft position sensor (REF) circuit Roy
