What is P0660 : Engine Error code Causes Explained
The P0660 engine fault code indicates an intake manifold tuning valve control circuit issue. Understanding the causes, symptoms, and repair options of this defect is crucial to engine performance, fuel efficiency, and drivability.
How to Identify a DTCs Number
Understand, this trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
To identify a DTC’s number like P0660, you need an OBD-II scanner connected to the vehicle’s diagnostic port, which retrieves stored codes from the PCM, allowing you to confirm the exact number and proceed with proper troubleshooting.
Causes of P0660 Error Code:
- Damaged or Faulty Intake Manifold Tuning Valve:
The valve itself might be defective, contaminated, or have broken components. - Electrical Issues:
Loose connectors, frayed wiring, or corrosion in the circuit can trigger P0660. - Stuck Valve:
The valve could be stuck in an open or closed position, preventing proper airflow control. - Engine Control Module (ECM) Issues:
Problems with the ECM itself, which controls the valve, can also trigger this code. - Cold Weather.
Cold temps can worsen intake manifold tuning valve issues, causing P0660.
Risk Level of P0660 Error Code:
The P0660 engine error code is considered a high-risk level fault because it relates to the intake manifold tuning valve control circuit, which directly affects air and fuel mixture in the engine.
Ignoring this code can lead to expensive repairs or even complete engine failure, so it’s best to diagnose and fix the issue as soon as possible.
Common Car Brands Affected by P0660 Code:
The P0660 code can affect various vehicles; it is most commonly associated with:
- Chrysler
- Vauxhall
- Porsche
- Dodge
- Land Rover
