Intake Valve Control Solenoid Circuit Low Bank 1
What it means
P0076 means the control circuit for the Bank 1 intake valve control solenoid is reading low — typically a short to ground or open in the wiring, or a failed solenoid. This solenoid is part of the variable valve timing system and uses oil pressure to adjust intake cam timing. When it can't be controlled, timing stays fixed, which can cause rough idle and reduced power. Clean oil at proper level is essential for the system to work.
Can I keep driving? The car usually drives, but you may feel rough idle or weaker power; valve timing that's stuck isn't ideal for long, so address it soon.
Common symptoms
What you'll notice
- Check-engine light on
- Rough idle
- Reduced power or sluggish acceleration
- Slightly poorer fuel economy
Common causes
Most likely first
- Faulty intake valve control (VVT oil-control) solenoid on Bank 1Likely
- Short-to-ground or open in the solenoid control wiring (reads low)Common
- Loose or corroded connector at the solenoidCommon
- Low or dirty engine oil affecting the VVT systemLess often
- Failed ECM (rare)Less often
How to diagnose & fix
Work through it in order
- Confirm the code and check engine oil level and condition — VVT needs clean oil at pressure.
- Inspect the solenoid connector and wiring for shorts or opens.
- Measure the solenoid resistance against spec.
- Replace the intake valve control solenoid if it's faulty.
- Repair wiring, clear the code, and retest.
