P0083
Intake Valve Control Solenoid Circuit High Bank 2
Variable valve timing / lift
Generic OBD-II
High
What it means
P0083 means the ECM detected a high-voltage (short-to-power or open) condition in the intake valve control solenoid circuit on bank 2. This solenoid drives the variable valve system; a circuit fault leaves it stuck, causing rough running and reduced power. The problem is electrical — wiring, connector, or the solenoid — not a starting fault.
High
Can I keep driving? Usually yes, with reduced performance — a valve-control circuit fault causes rough running and lost power but won't normally strand you.
Common symptoms
What you'll notice
- Check-engine light on
- Reduced power or acceleration
- Rough or unstable idle
- Slightly poorer fuel economy
Common causes
Most likely first
- Short-to-power or open (high-voltage fault) in the intake valve control solenoid circuit, bank 2Likely
- High resistance in the solenoid circuitCommon
- Failed intake valve control solenoidCommon
- Loose or corroded connectorLess often
- ECM control-circuit driver faultLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data to confirm the operating conditions.
- Inspect the bank 2 solenoid connector and wiring for a short-to-power or high resistance.
- Measure the solenoid resistance against spec.
- Check engine oil level and condition, since these solenoids are oil-actuated.
- Replace the solenoid if faulty; suspect the ECM only after wiring is verified good.
FAQ
Quick answers
Is it safe to drive with P0083?+
Short-term, usually yes, though with reduced performance and rough running. Fix it before the valve control problem worsens.
Can I just clear P0083?+
It returns until the high-voltage circuit fault or the solenoid is repaired.
