OBD-II Trouble Code Description for P0350 GMC

Ignition Coil Primary/Secondary Circuit

What does this mean?

OBD2 Code P0350 GM 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 OBD code P0350 GM
– Engine Light ON (or Service Engine Soon Warning Light) – Lack/Loss of Power – The engine may be harder to start – Engine hesitation

Causes
