Intake Valve Control Solenoid Circuit Range/Performance Bank 2
What it means
P0028 means the intake valve control (variable valve timing) solenoid on bank 2 is not responding the way the ECM expects for the commanded value. It is often caused by low or dirty oil, a sticking solenoid, or a wiring problem rather than total failure. The engine usually still runs and drives, but idle quality and power on that bank can suffer.
Can I keep driving? Generally driveable, but valve timing on bank 2 may not respond correctly — expect a rough idle and some power loss until repaired.
Real-world scan data
Figures reflect only diagnostic scans recorded through our own apps and tools. Cars are typically scanned because a symptom or warning light prompted it, so these counts describe our scan records — not the incidence of faults in any model, and not the quality, reliability, or safety of any vehicle.

- Failed ECM (least likely)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check engine oil level and condition — low or dirty oil is a common cause of poor solenoid response.
- Inspect the bank 2 solenoid connector and wiring for damage or corrosion.
- Remove and inspect/clean the solenoid and its oil screen; test its resistance and operation.
- Replace the solenoid if it fails to respond; consider the ECM only as a last resort. Clear and re-test.
