OBD Code P0350

Ignition Coil Primary/Secondary Circuit

What’s mean?

OBD2 Code P0350 Definition:
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

Possible sumptoms of P0350
– Engine Light ON (or Service Engine Soon Warning Light) – Lack/Loss of Power – The engine may be harder to start – Engine hesitation

Possible Causes

Possible causes of P0350
– Open or short in the ignition coil circuit – Ignition coil circuit shorted to ground – Ignition coil connector – Damaged ignition coil – Damaged PCM or Possible solution- If damage, repair ignition coil circuit – Replaced ignition coil – Replaced PCM or ECMWhen is the code detected?The test fails when the Powertrain Control Module (PCM) or Electronic Control Module(ECM) does not receive a valid pulse signal from the ignition coil.P0350 DescriptionThe ignition signal from the Powertrain Control Module (PCM) or Electronic Control Module(ECM) is sent to and amplified by the power transistor.
