What Does P0083 Mean?
The ECM has detected a high voltage or short-to-power condition in the bank 2 intake valve control solenoid circuit. The VVT oil control valve signal line is reading higher than expected, which may cause the solenoid to remain energized or behave erratically. The driver may notice rough idle, engine knock, poor performance, or illuminated check engine light.
Common Causes
35%
Short to battery voltage in the wiring harness between the ECM and VVT solenoid
25%
Faulty VVT solenoid with open or high-resistance coil on bank 2 intake
20%
Damaged or melted connector at the solenoid due to heat exposure
12%
ECM output driver stuck high or internal ECM fault
8%
Incorrect solenoid installed (wrong resistance value for application)
Diagnostic Steps
1
Disconnect the bank 2 intake VVT solenoid and measure coil resistance. Spec is typically 6.9–7.9 ohms. An open reading (OL) or significantly high resistance indicates a failed solenoid.
2
With the solenoid unplugged, use a DVOM to check for voltage on the ECM control wire at the harness connector. Any voltage present with the key on indicates a short to power in the harness.
3
Inspect the wiring harness routing near exhaust manifolds and hot engine components for melted insulation that could cause shorts to adjacent power wires.
4
Check the solenoid connector for heat damage, melted terminals, or pin spread that could cause intermittent high-resistance connections.
5
If wiring is intact, back-probe the ECM connector and check the solenoid driver output. If the ECM is commanding low but the circuit reads high, the ECM driver may be faulty.
Estimated Repair Cost
$120 - $550

The most common cause of P0083 (Intake Valve Control Solenoid Circuit High (Bank 2)) is: Short to battery voltage in the wiring harness between the ECM and VVT solenoid
Typical repair costs for P0083 range from $120 to $550, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Driving is generally safe for short trips. However, if the solenoid is stuck fully energized, the cam timing may advance too far, potentially causing engine knock or pre-ignition under load. Avoid heavy acceleration or towing until repaired.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0083 to identify the root cause.
