Common Causes of P0081
Parts most likely causing this code, ranked by probability
The solenoid itself has an internal electrical fault or is mechanically stuck, preventing proper camshaft timing adjustment.
70% of P0081 cases are fixed by replacing this part
Damaged, corroded, or loose wiring or connector to the Bank 2 intake VVT solenoid prevents proper electrical signal transmission.
20% of P0081 cases are fixed by repairing this part
The VVT system relies on clean, sufficient oil pressure to operate, and dirty or low oil can prevent the solenoid from functioning correctly.
8% of P0081 cases are fixed by addressing this issue
The engine computer itself has an internal fault affecting the VVT solenoid circuit, sending incorrect signals.

Check These First (Before Buying Parts)
- Check your engine oil level and condition. Low or dirty oil can directly cause VVT issues.
- Visually inspect the electrical connector to the intake VVT solenoid on Bank 2 for any signs of damage, corrosion, or looseness.
How to Diagnose P0081
- 1Check engine oil level and condition. Ensure it is full and clean.
- 2Visually inspect the intake VVT solenoid on Bank 2 and its electrical connector for damage, corrosion, or loose connections.
- 3Using a multimeter, test the resistance of the intake VVT solenoid and compare it to factory specifications.
- 4Check for continuity and proper voltage at the VVT solenoid connector using a multimeter.
- 5If available, use a professional scan tool to command the VVT solenoid on and off and monitor its operation.
P0081 on Popular Vehicles
Toyota Camry
2007-2024P0081 on V6 Toyota engines (like the 2GR-FE) often points to the Bank 2 intake VVT-i solenoid. These can fail electrically or get clogged with dirty oil.
75% fixed by replacing the VVT solenoid
Honda Accord
2003-2024Honda's VTEC/VTC systems are sensitive to oil quality. P0081 on V6 Accords can be caused by the intake VTC solenoid or a clogged oil passage to the solenoid.
70% fixed by replacing the VTC solenoid
Ford F-150
2011-2024Ford's Ti-VCT systems are common. P0081 on these engines typically indicates a faulty intake VCT solenoid on Bank 2. Oil sludge can also contribute to solenoid failure.
65% fixed by replacing the VCT solenoid
Frequently Asked Questions
What does P0081 mean?
P0081 indicates an electrical circuit problem with the intake valve timing control solenoid on engine bank 2. This solenoid adjusts camshaft timing for optimal performance and efficiency.
Can I drive with P0081?
Yes, for short trips only. You will experience reduced engine performance and fuel economy. Continued driving can lead to increased engine wear or further damage.
Will P0081 clear itself?
No, P0081 will not clear itself. The underlying electrical or mechanical fault must be repaired, and then the code can be cleared with a scan tool.
How do I fix P0081 myself?
First, check your engine oil level and condition. Then, inspect the VVT solenoid and its connector on Bank 2 for damage. If the solenoid tests faulty, you can replace it.
How much does it cost to fix P0081?
DIY repair costs $100-$300 for a new VVT solenoid. Professional repair costs $200-$600, including parts and 1-2 hours of labor.
P0081 keeps coming back - why?
The code keeps returning because the root cause was not fully addressed. This often means a wiring issue was missed, the replacement solenoid was faulty, or there's an underlying oil pressure problem.
Will P0081 fail emissions/smog test?
Yes, P0081 will cause your vehicle to fail an emissions or smog test. The Check Engine Light indicates a fault in the emissions-related system.
What's the difference between P0081 and P0082?
P0081 indicates an 'open circuit' or electrical fault with the intake VVT solenoid on Bank 2. P0082 indicates a 'low circuit' condition, meaning the voltage is too low for the same solenoid.
P0081 on Toyota Camry?
On many Toyota V6 engines, P0081 points directly to the Bank 2 intake VVT-i solenoid. These solenoids can get clogged with sludge or fail electrically, requiring replacement.
Questions to Ask Your Mechanic
Did you check the resistance of the VVT solenoid on Bank 2?
Good answer: Yes, the resistance was [X ohms], which is outside the factory specification of [Y ohms]. This confirms an internal solenoid fault.
What did you find when you inspected the wiring and connector for the Bank 2 intake VVT solenoid?
Good answer: I found no visible damage or corrosion on the wiring or connector, and I confirmed proper voltage and continuity to the solenoid.

Intermediate. Accessing the solenoid can be tricky on some engines, and testing requires a multimeter.
Cost of Waiting
Continued driving with P0081 can lead to reduced fuel economy, increased engine wear due to incorrect valve timing, and potentially damage to the catalytic converter if the engine runs too rich or lean. A $150 solenoid fix now prevents a $1,000+ engine repair later.
While You're In There...
If the oil is dirty or low, replacing it ensures proper VVT operation and prevents future issues, as the VVT system relies on clean oil.
If the VVT solenoid is located under the valve cover and requires its removal for access, replacing the gasket prevents oil leaks and avoids repeat labor.
Tools You'll Need
- Basic socket set
- Ratchet
- Screwdriver set
- Multimeter
- Engine oil (if needed)
- Oil filter (if needed)
- Scan tool (optional but helpful)
P0081 is a common VVT system code. The repair is usually straightforward, and replacing the solenoid often resolves the issue, restoring your engine's performance.

Your Next Steps
Step 1: Check your engine oil level and condition. If low or dirty, perform an oil and filter change.
Step 2: Visually inspect the Bank 2 intake VVT solenoid's electrical connector and wiring for damage. If no obvious issues, use a multimeter to test the solenoid's resistance.
Step 3: If the solenoid tests faulty or shows no obvious wiring issues, replace the Bank 2 intake VVT solenoid. You'll likely need a new VVT solenoid.
