P0660 Code - Intake Manifold Tuning Valve Control Circuit Open Bank 1
Quick Answer
The P0660 diagnostic trouble code (DTC) refers to the intake manifold tuning valve control circuit being open on Bank 1. Common causes include Faulty Intake Manifold Tuning Valve: The intake manifold tuning valve itself may be faulty and need to be replaced, Wiring Issues: Damaged or corroded wiring in the control circuit can prevent proper communication between the valve and the engine control module, Electrical Short: An electrical short in the circuit can cause the valve to malfunction and trigger the P0660 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.

Code P0660 Description
The P0660 diagnostic trouble code (DTC) refers to the intake manifold tuning valve control circuit being open on Bank 1. This means that there is an issue with the electrical circuit that controls the intake manifold tuning valve on the first bank of cylinders in the engine. The intake manifold tuning valve is responsible for adjusting the length of the intake runners to optimize airflow and improve engine performance at different RPM ranges. When this circuit is open, it can lead to poor engine performance, reduced fuel efficiency, and potentially cause damage to other components of the engine.
Common Causes of P0660
- Faulty Intake Manifold Tuning Valve: The intake manifold tuning valve itself may be faulty and need to be replaced.
- Wiring Issues: Damaged or corroded wiring in the control circuit can prevent proper communication between the valve and the engine control module.
- Electrical Short: An electrical short in the circuit can cause the valve to malfunction and trigger the P0660 code.
- Failed Engine Control Module: A malfunctioning engine control module (ECM) can also cause issues with the intake manifold tuning valve control circuit.
- Vacuum Leaks: Vacuum leaks in the intake system can affect the operation of the intake manifold tuning valve and trigger the code.
Symptoms of P0660
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Rough Idle: The engine may experience rough idling or stalling at idle due to an improper air-fuel mixture.
- Decreased Power: The vehicle may have reduced power output when accelerating, especially at higher speeds.
- Poor Fuel Economy: A faulty intake manifold tuning valve control circuit can lead to decreased fuel efficiency as the engine struggles to operate efficiently.
- Engine Misfires: The engine may experience misfires due to an incorrect air-fuel mixture caused by the malfunctioning intake manifold tuning valve control circuit.
How to Fix P0660
- Diagnose the Issue: Use a scan tool to read the DTC and pinpoint the exact cause of the problem.
- Inspect Wiring and Connections: Check the wiring and connections related to the intake manifold tuning valve control circuit for any damage or corrosion.
- Test Intake Manifold Tuning Valve: Test the intake manifold tuning valve to ensure it is functioning properly.
- Replace Faulty Components: Replace any faulty components such as the intake manifold tuning valve, damaged wiring, or a malfunctioning ECM.
- Clear DTC: After repairing the issue, clear the DTC and reset the check engine light to ensure the problem has been resolved.
Cost to Fix P0660
The cost of repairing a P0660 code can vary depending on the specific cause of the issue and the labor rates at the auto repair shop. On average, replacing the intake manifold tuning valve or addressing wiring issues can range from $200 to $500, including parts and labor. However, this estimate may fluctuate based on the location, vehicle make and model, and the extent of the repairs needed. It's recommended to consult with a professional mechanic for a more accurate cost estimate tailored to your specific situation.
