P0354 - Ignition Coil D Primary/Secondary Circuit Malfunction.
Description of DTC:
The ignition signal from the Powertrain Control Module (PCM) or Electronic Control Module(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.
Symptoms:
- Lack/Loss of Power
- The engine may be harder to start
- Engine hesitation
- Check Engine Light On
- No spark
Possible Causes:
- Open or short in the ignition coil circuit
- Ignition coil circuit shorted to ground
- Ignition coil connector
- Damaged ignition coil
- Damaged PCM or ECM
Possible Solutions:
- If damage, repair ignition coil circuit
- Replace ignition coil
- Replace PCM or ECM
P0355 - Ignition Coil E Primary/Secondary Circuit Malfunction.
P0356 - Ignition Coil F Primary/Secondary Circuit Malfunction.
