– Ignition Coil 5 harness is open or shorted
– Ignition Coil 5 circuit poor electrical connection
– Faulty Powertrain Control Module (PCM)
– Lack/Loss of Power
– Engine may be harder to start
– Engine hesitation
– Rough engine idle
The ignition system on the vehicle uses individual ignition coils for each cylinder. The Powertrain Control Module (PCM) controls each ignition coil operation. The PCM sends a ON/OFF signal to energize the ignition coil to create a spark at the spark plug when a spark is required at the cylinder.
