P064D Code - Internal Control Module O2 Sensor Processor Performance Bank 1
Quick Answer
The Powertrain Control Module (PCM) monitors the application-specific integrated circuit that controls and monitors the heated oxygen sensor (HO2S). Common causes include Faulty Powertrain Control Module (PCM), PCM harness is open or shorted, PCM circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
