Intake Valve Control Solenoid Circuit Bank 2
What it means
P0081 means the ECM detected an electrical fault in the circuit for the bank 2 intake valve control solenoid — the oil-control valve that adjusts intake variable valve timing. When the circuit fails, the ECM can't vary intake cam timing on that bank, so it defaults to a fixed position. The engine still runs, but you typically lose some power, smoothness, and fuel economy.
Can I keep driving? Usually yes — the car runs, but variable valve timing on bank 2 may be disabled, costing power and smoothness. Fix it promptly to avoid drivability and economy losses.
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.

Common causes
Most likely first
- Faulty intake valve control (VVT oil-control) solenoid on bank 2Likely
- Open or short in the solenoid control wiringCommon
- Corroded or loose connector at the solenoidCommon
- Blown fuse or lost feed to the solenoid circuitLess often
- Faulty ECM/PCM driver (rare — check wiring and solenoid first)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and confirm the fault is current.
- Inspect the bank 2 solenoid connector and wiring for damage, corrosion, or a loose pin.
- Measure the solenoid's resistance and compare to spec.
- Confirm power and ground reach the solenoid connector when commanded.
- Replace the solenoid if it's out of spec; repair wiring otherwise. Clear and re-test.
