OBD-II Generic P0662: Intake Manifold Tuning Solenoid Circuit High B1 - How to Fix

Q: What does code P0662 mean?

P0662 indicates a high voltage condition in the intake manifold tuning solenoid circuit for bank 1. It often means a short to voltage or a faulty solenoid.

Q: Can I drive with code P0662?

You may notice reduced engine performance or fuel economy. It's safe to drive short distances, but have it diagnosed soon to prevent further issues.

Q: How much does it cost to fix P0662?

If DIY, the solenoid part costs $50-$150. Professional repair costs $150-$300 including labor and diagnostics.

Q: What tools do I need to fix P0662?

You'll need a multimeter, an OBD2 scanner, and basic hand tools to access the solenoid.

Q: Can a bad PCM cause code P0662?

Rarely, but a faulty PCM can cause a high circuit code. Exhaust all wiring and solenoid checks before considering PCM replacement.

Abstract

Error code P0662 indicates that the powertrain control module (PCM) has detected a high voltage condition in the intake manifold tuning solenoid circuit for bank 1. This solenoid controls airflow in the intake manifold to optimize engine performance. A high circuit signal typically points to a short to voltage, faulty solenoid, or wiring issue.
