P0028 fault code: Intake Valve Control Solenoid Circuit Range/Performance

P0028 means “Intake Valve Control Solenoid Circuit Range/Performance” — a fuel and air metering fault in the powertrain.

Can I DIY?

Professional-only boundary. Do not fit a Bank 1 intake solenoid onto Bank 2 for P0028.

What to tell the garage about P0028

Do not drive until checked. Bank 2’s intake valve-control solenoid failed its own range test (P0028). The SAE short title matches P0026, but this is the other bank’s intake path, not a spare-part clone.

Take these reviewed, code-specific details with you. They help the garage confirm the fault without turning this page into a repair procedure.

What does P0028 mean?

P0028 is a generic (SAE standard) powertrain code reported by your car’s engine control unit. It sits in the P00xx block, which covers fuel and air metering. The stored description is “Intake Valve Control Solenoid Circuit Range/Performance”. The code itself tells you which circuit or system tripped the fault — not always the exact part that failed.

Will P0028 fail an MOT?

A lit engine management light is a Major MOT defect until the lamp stays off. P0028 is Bank 2 intake valve-control range/performance, not P0026 and not P0029 (exhaust).
