A rare internal fault within the engine computer's driver circuit for the VVT solenoid can cause this code.
2% of P0082 cases are fixed by replacing the ECM/PCM
Check These First (Before Buying Parts)
- Check your engine oil level and condition. Low or dirty oil can sometimes affect VVT operation, though P0082 is an electrical circuit fault.
- Visually inspect the intake VVT solenoid's electrical connector for corrosion, bent pins, or a loose fit.
- Inspect the wiring leading to the solenoid for any obvious damage, cuts, or signs of rodent chewing.
How to Diagnose P0082
- 1Visually inspect the intake VVT solenoid and its electrical connector for any obvious damage, corrosion, or loose connections.
- 2Check the wiring harness leading to the solenoid for any signs of chafing, cuts, or shorts to ground.
- 3Using a multimeter, test the resistance of the intake VVT solenoid. Compare the reading to factory specifications (usually 6-15 ohms).
- 4With the engine off and key on, check for proper voltage (usually battery voltage) and ground at the VVT solenoid connector.
- 5If the solenoid and wiring test good, use a scan tool to monitor VVT solenoid operation and check for any other related codes.
P0082 on Popular Vehicles
Toyota Camry
2007-2024Toyota's VVT-i systems are generally reliable, but the intake VVT solenoid can fail electrically, leading to P0082. Ensure proper oil maintenance, as sludge can indirectly affect solenoid operation, though P0082 is an electrical fault.
65% fixed by replacing the intake VVT solenoid
Honda Accord
2003-2024Honda's VTEC/VTC systems are sensitive. P0082 on an Accord often indicates an electrical fault with the intake VTC solenoid itself or its connector. Always check for clean oil, as VTEC relies on it, but focus on electrical tests for this specific code.
60% fixed by replacing the intake VVT solenoid
Ford F-150
2004-2024Ford's VCT (Variable Cam Timing) solenoids are known to fail. For P0082, the intake VCT solenoid on Bank 1 is the primary suspect. Wiring damage due to engine bay heat or vibration is also a factor on these trucks.

Frequently Asked Questions
What does P0082 mean?
P0082 indicates that the engine's computer has detected a low voltage condition in the electrical circuit that controls the intake valve timing solenoid for Bank 1. This solenoid is crucial for the variable valve timing system.
Can I drive with P0082?
Yes, you can drive with P0082, but you should fix it within a few days. You will experience reduced engine performance, poor fuel economy, and potentially a rough idle. Continued driving can lead to further engine issues or increased emissions.
Will P0082 clear itself?
No, P0082 will not clear itself. The underlying electrical fault or component failure must be repaired. The Check Engine Light will remain on until the issue is resolved and the code is cleared, either manually or after several drive cycles once the fault is gone.
How do I fix P0082 myself?
Start by visually inspecting the intake VVT solenoid and its wiring for damage. If no obvious issues are found, test the solenoid's resistance with a multimeter. If the solenoid is faulty, replace it. If the wiring is damaged, repair it. Replacing the solenoid is a common DIY fix.
How much does it cost to fix P0082?
The cost to fix P0082 yourself is typically $50-$200 for a new intake VVT solenoid. If you take it to a professional shop, expect to pay $200-$500, which includes parts and 1-2 hours of labor.
P0082 keeps coming back - why?
If P0082 keeps returning, it means the root cause was not fully addressed. Common reasons include: a faulty replacement solenoid, an intermittent wiring issue that wasn't properly repaired, a corroded connector that was overlooked, or, in rare cases, an ECM/PCM fault.
Will P0082 fail emissions/smog test?
Yes, P0082 will cause your vehicle to fail an emissions or smog test. Any active Check Engine Light indicates a fault in the emissions system, which is an automatic failure in states with such inspections.
What's the difference between P0082 and P0010?
P0082 specifically indicates a 'low' voltage condition in the intake VVT solenoid circuit for Bank 1, pointing to a short or open circuit. P0010 is a more general 'malfunction' in the intake VVT solenoid circuit for Bank 1, which could encompass various electrical issues beyond just a low voltage.
P0082 on Honda Accord
On Honda Accords, P0082 often points directly to a faulty VTEC/VTC intake solenoid. While less common than oil pressure-related VTEC codes, an electrical fault in the solenoid or its wiring is a direct cause. Always check oil level and condition first, then proceed with electrical diagnostics of the solenoid.
Questions to Ask Your Mechanic
Did you test the resistance of the intake VVT solenoid and compare it to specifications?
Good answer: Yes, I measured the resistance at [X ohms], and the factory spec is [Y-Z ohms]. It's either within spec or out of spec, indicating a faulty solenoid.
What did you find when inspecting the wiring harness and connector for the intake VVT solenoid?
Good answer: I found no visible damage to the wiring or connector, and I confirmed good voltage and ground at the connector using a multimeter.

Intermediate - requires basic hand tools and a multimeter for electrical testing. Replacing the solenoid is typically accessible.
Cost of Waiting
Ignoring P0082 can lead to continued poor engine performance, reduced fuel economy, and increased emissions. Prolonged operation with a faulty VVT system can put additional stress on other engine components, potentially leading to premature wear or more expensive repairs down the line.
While You're In There...
Variable valve timing systems rely on clean engine oil for proper operation. If your oil is due for a change, it's a good time to do it.
If your engine has a history of infrequent oil changes or sludge buildup, an engine oil flush can help clean out passages that affect VVT operation.
Tools You'll Need
- Basic hand tools (sockets, wrenches)
- Multimeter
- Wire strippers/crimpers (if wiring repair is needed)
- Scan tool (optional, for clearing codes and monitoring)
P0082 is a common electrical code related to your engine's valve timing. Most repairs involve replacing an accessible solenoid and are straightforward, restoring your engine's performance and fuel efficiency.

Your Next Steps
Step 1: Visually inspect the intake VVT solenoid and its wiring/connector for any damage. Ensure the connector is securely seated.
Step 2: If no visual issues, use a multimeter to test the resistance of the intake VVT solenoid. If it's outside the manufacturer's specified range (check your service manual), replace the solenoid.
Step 3: If the solenoid tests good, check for proper voltage and ground at the solenoid connector. If power or ground is missing, trace the wiring back to the ECM/PCM to find the fault.
