Frequently Asked Questions about P0660 2000 Ford F150 Code

1. What does the OBDII code P0660 mean on a 2000 Ford F150?

P0660 indicates a malfunction in the Intake Manifold Tuning Valve (IMTV) circuit, which controls airflow through the intake manifold for optimal engine performance.

2. What are the common symptoms of a P0660 code on a 2000 Ford F150?

Common symptoms include reduced engine performance, poor fuel economy, hesitation during acceleration, and an illuminated Check Engine Light.

3. What causes the P0660 code to appear on a 2000 Ford F150?

The code can be triggered by a faulty IMTV solenoid, damaged wiring or connectors in the circuit, a vacuum leak, or a failure in the PCM (Powertrain Control Module).

4. How do I diagnose the P0660 code on my Ford F150?

Start by inspecting the IMTV solenoid, wiring, and connectors for damage or corrosion. Use a multimeter to test for proper voltage and continuity in the circuit. A scan tool may also help monitor the IMTV’s operation.

5. Can I drive my 2000 Ford F150 with a P0660 code?

While the truck may still be drivable, you may experience reduced performance and fuel efficiency. Driving for an extended period with this code could lead to further engine issues.

6. How do I fix the P0660 code on a 2000 Ford F150?

Repairs may include replacing the IMTV solenoid, repairing damaged wires or connectors, cleaning intake manifold components, or reprogramming or replacing the PCM if it's faulty.

7. How much does it cost to repair the P0660 code on a Ford F150?

The cost can vary depending on the issue. Replacing the IMTV solenoid typically costs $100–$300, while wiring repairs or PCM replacement may increase the cost.
