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 ECMP0355 - Ignition Coil E Primary/Secondary Circuit Malfunction.
P0356 - Ignition Coil F Primary/Secondary Circuit Malfunction.
