P0028 P0028 Intake Valve Control Solenoid Circuit Range/Performance - Bank 2
What P0028 means for you
Both sources align on a medium severity.
Symptoms
- The check engine light is illuminated.
- You may experience a noticeable reduction in engine power.
- The variable valve lift system's malfunction can lead to decreased fuel efficiency.
- Engine performance may feel rough or unstable.
- You might notice hesitation or stuttering during acceleration.
- Increased fuel consumption could be observed.
Common causes
- Contaminated oil is a frequent culprit for triggering a P0028 code.
- The intake valve relies on oil pressure to function, and dirty oil can damage this system.
- Malfunctions can occur in components such as the camshaft actuator, control solenoid, timing chain, or timing belt.
- Issues with the engine control module (ECM) or powertrain control module (PCM) can also lead to solenoid signal problems.
- The Intake Valve Control Solenoid regulates the exhaust valve's position using oil pressure and electrical signals, which are crucial for variable valve timing (VVT) systems.

The P0028 code indicates that the engine control module (ECM) or powertrain control module (PCM) has detected a malfunction in the intake valve control solenoid's operation. This solenoid is essential for regulating the timing of the intake valve, and if it fails to operate correctly, it can severely impact engine performance and efficiency.
Frequently asked questions
It is not advisable to drive with a P0028 code as it can lead to further engine damage.
The repair costs for a P0028 code can vary, but expect to spend between $100 and $500 depending on the specific issue.
Common symptoms include a check engine light, reduced engine power, rough idling, and increased fuel consumption.
