P0083 — Intake Valve Control Solenoid Circuit High (Bank 2)

Severity: medium Drive with care, to a shop

What P0083 means

The engine control module drives a solenoid that adjusts intake valve operation (timing or lift) on the Bank 2 side of the engine. P0083 sets when the voltage in that control circuit is higher than expected. Typical causes are a short to power, a bad solenoid, a wiring fault, or a failing driver inside the ECM.

Symptoms

  • Check Engine light on
  • Rough or unstable idle
  • Reduced power and sluggish acceleration
  • Worse fuel economy
  • Possible stalling

Possible causes

  1. Faulty Bank 2 intake valve control solenoid
  2. Damaged or shorted wiring or connector, including a short to positive
  3. Poor connection from corrosion or a loose terminal
  4. Faulty ECM (solenoid driver or internal regulator)
  5. Low or dirty oil affecting the valve timing system

How to diagnose

  1. Scan all codes and freeze frame data, clear the code and see if it returns
  2. Inspect the Bank 2 solenoid connector and wiring for chafing, melting and corrosion
  3. Check oil level and condition
  4. Measure solenoid coil resistance and compare it with the service specification
  5. Test the circuit for a short to power and for wire continuity back to the ECM
  6. Check supply voltage and the control signal at the connector with a multimeter or scope
  7. Command the solenoid with a scan tool and watch the response
  8. If wiring and solenoid test good, evaluate the ECM

Common fixes

  • Replace the Bank 2 intake valve control solenoid
  • Repair or replace damaged wiring and connectors
  • Clean and secure electrical terminals
  • Change oil and filter if needed
  • Repair, reprogram or replace the ECM as a last resort

Questions and answers

What does P0083 mean?

The ECM sees too high a voltage in the intake valve control solenoid circuit for Bank 2. The solenoid, wiring or a connection is usually to blame.

Can I drive with P0083?

Briefly and carefully, just to get it checked. Power loss, rough idle and occasional stalling are possible, so don't put it off.

How do I fix P0083?

Start by inspecting the solenoid wiring and connector, checking the oil, and testing solenoid resistance. Repairing the harness or replacing the solenoid fixes most cases.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
