P0083: Intake Valve Control Solenoid Circuit High Bank 2

What does P0083 mean?

A solenoid valve on the cylinder head controls oil flow for the variable valve control on the intake side of bank 2. Depending on the manufacturer it drives a camshaft phaser (for example on Nissan engines) or a valve lift changeover (for example on Subaru engines). This code family reports electrical faults in its control circuit; P0083 means the voltage in the control circuit is too high, typically a short to battery voltage. Other manufacturers report the same valve under the "camshaft position actuator" codes instead. Valve control is then switched off or stays in its base position. Bank 2 exists only on V and boxer engines.

The code tells you which monitor failed, not which part is broken. Test before replacing parts.

Symptoms

• Check engine light on
• Less power, especially at high engine speed with lift changeover
• Rough idle possible
• Follow-up codes for camshaft timing or misfire possible

Common causes

• High Control wire shorted to battery voltage
• Medium Solenoid coil faulty
• Medium Water or corrosion in the connector
• Low Output driver in the engine control module faulty

Likelihood is a general estimate across vehicles; your make and model may differ.
