P0662 Lincoln Code - Intake Manifold Tuning Valve Control Circuit High Bank 1
Quick Answer
The P0662 diagnostic trouble code (DTC) for Lincoln vehicles specifically refers to the intake manifold tuning valve control circuit being high on bank 1. Common causes include Faulty Intake Manifold Tuning Valve: The intake manifold tuning valve itself may be malfunctioning, causing the control circuit to register as high voltage, Wiring Issues: Damaged or corroded wiring in the control circuit can lead to excessive voltage readings, PCM Malfunction: A problem with the powertrain control module (PCM) can also trigger the P0662 code. 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.
