DTC Confirmation Test

Malfunction is detected when ECM does not receive signal from ignition primary circuit during engine cranking or running. Possible causes are:

• Ignition primary circuit open or shorted.
• Defective power transistor (integral with ignition coil).
• Defective Camshaft Position (CMP) sensor.
• CMP sensor circuit open or shorted.

To set DTC, turn ignition on. Select DATA MONITOR with scan tool. Start engine and let it idle for at least 4 seconds. If engine does not start, crank engine for at least 5 seconds.
