Exhaust Valve Control Solenoid Circuit High Bank 1
What it means
P0080 means the engine computer detected an abnormally high voltage in the bank 1 exhaust valve control solenoid circuit — typically a short to voltage, an open, or a failed solenoid. This solenoid operates a variable exhaust/valve control feature, so the fault is electrical and usually affects performance rather than stopping the engine.
Can I keep driving? Usually drivable — the engine runs, though you may notice reduced performance or rougher running on engines that rely on the exhaust valve control.

Common symptoms
What you'll notice
- Check-engine light on
- Reduced performance or rougher running on affected engines
- Slightly reduced fuel economy
- Often no obvious driving symptom beyond the light
Common causes
Most likely first
- Short to voltage or open in the exhaust valve control solenoid circuitLikely
- Failed exhaust valve control solenoidCommon
- Damaged, loose, or corroded connector at the solenoidCommon
- Chafed or pinched wiring pulling the signal highLess often
- Faulty engine control module (ECM) — rareLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and note any companion valve-control codes.
- Inspect the exhaust valve control solenoid connector and wiring for a short to voltage or damage.
- Measure the solenoid resistance and check its control and ground circuits against spec.
- Repair shorted or chafed wiring and clean corroded terminals.
- Replace the solenoid if it fails testing; consider the ECM last. Clear and re-test.
