P0662 Dodge Code - Intake Manifold Tuning Valve Control Circuit High Bank 1
Quick Answer
The P0662 diagnostic trouble code for Dodge vehicles indicates a problem with the intake manifold tuning valve control circuit on bank 1. Common causes include Faulty Intake Manifold Tuning Valve: The intake manifold tuning valve itself may be malfunctioning, causing the circuit to register a high voltage condition, Wiring or Connector Issues: Corrosion, damage, or poor connections in the wiring or connectors related to the intake manifold tuning valve control circuit can trigger this code, Malfunctioning Engine Control Module (ECM): A problem with the ECM responsible for controlling the intake manifold tuning valve circuit can lead to 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.
