What Does P0082 Mean?
The ECM has detected a low voltage or short-to-ground condition in the bank 2 intake valve control solenoid circuit. This means the VVT oil control valve signal wire is reading lower than expected, preventing proper camshaft timing adjustment. The driver may experience rough idle, reduced power, and the check engine light will illuminate.
Common Causes
35%
Short to ground in the wiring harness between the ECM and VVT solenoid
30%
Internally shorted VVT solenoid coil on bank 2 intake
20%
Corroded or water-damaged electrical connector at the solenoid
15%
ECM driver circuit failure pulling signal low
Diagnostic Steps
1
With the VVT solenoid disconnected, measure resistance across the solenoid terminals. Spec is typically 6.9–7.9 ohms. A reading significantly below spec indicates an internal short.
2
With the solenoid unplugged, check for continuity between each solenoid harness wire and chassis ground. Any continuity indicates a short to ground in the harness that must be traced and repaired.
3
Inspect the solenoid connector for water intrusion, bent pins, corrosion, or damaged seals. Clean or replace the connector as needed.
4
Using a lab scope, monitor the ECM's PWM duty cycle signal to the solenoid. The signal should modulate between 0–100% duty cycle. A flat-lined low signal with solenoid disconnected points to an ECM output driver failure.
5
If wiring checks pass, swap the bank 1 and bank 2 intake VVT solenoids to determine if the fault follows the solenoid or stays with the circuit.
Estimated Repair Cost

The most common cause of P0082 (Intake Valve Control Solenoid Circuit Low (Bank 2)) is: Short to ground in the wiring harness between the ECM and VVT solenoid
Typical repair costs for P0082 range from $120 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive short distances but the VVT system will default to a fixed timing position. Expect reduced power and efficiency. Extended driving in this condition increases fuel consumption and emissions.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0082 to identify the root cause.
