P2312 Mercury Code - Ignition Coil 'E' Primary Control Circuit Low
Quick Answer
The current flow, or dwell, through the primary ignition coil is controlled by the Powertrain Control Module (PCM) by providing a switched ground path through the ignition coil driver to ground. Common causes include Faulty Ignition Coil 'E', Ignition Coil 'E' harness is open or shorted, Ignition Coil 'E' 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.
