P0690 2009 Ford Fusion Code - Electronic Control Module Power Relay Sense Circuit High
Quick Answer
The Powertrain Control Module (PCM) monitors the voltage on the Ignition Switch Position Run (ISP-R) and the Fuel Injector Power Monitor (INJPWRM) circuits. Common causes include Weak battery, Low voltage while cranking, Faulty Powertrain Control Module (PCM) relay. 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.
