P0028: Intake Valve Control Solenoid Circuit Range/Performance — Bank 2
What to do
Usually driveable with reduced performance. Start with oil level and service interval.
What this code means
The bank 2 intake valve control solenoid is underperforming. Where this appears together with P0026 on bank 1, the shared cause is almost always oil supply rather than two solenoids failing simultaneously — check pressure and condition before replacing either.
Likely causes
Start here
- Failed valve control solenoid · moderate
- Low or dirty engine oil · easy
- Clogged camshaft solenoid oil screen · easy
Less common
- Corroded or loose connector · easy
- Collapsed or stuck valve lifter · specialist

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
