P0083 medium Severity

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

Check Engine Light illumination, possible rough idle, reduced performance

Overview

P0083 indicates that the engine control module has detected a high voltage condition in the intake valve control solenoid circuit for Bank 2 on vehicles with variable valve timing.

Common Symptoms

  • Check Engine Light (MIL) illuminated
  • Rough or unstable idle
  • Reduced engine performance and sluggish acceleration
  • Decreased fuel economy
  • Possible engine stalling

Most Common Causes

Faulty intake valve control solenoid (Bank 2) high

Internal short or failed coil can present high circuit voltage.

Damaged or shorted wiring harness/connectors in solenoid circuit high

Chafed, corroded, loose, or shorted wires often cause high circuit voltage conditions.

Poor electrical connection (corrosion/loose terminal) medium

Connector integrity affects voltage readings.

Faulty ECM/PCM or internal regulator issue medium

ECM supplying incorrect voltage or misinterpreting signal; rare but possible.

Alternative interpretation involving fuel rail pressure sensor circuit low

Some community sources misattribute P0083 to fuel rail pressure sensor circuit faults.

Diagnostic Steps

  1. Connect a professional OBD‑II scanner and confirm P0083 on Bank 2
    Expected: Code P0083 present; note freeze frame and any related codes
    Interpretation: Verification of condition and context prior to electrical checks
  2. Visually inspect wiring harness and connectors for damage or corrosion
    Expected: No exposed wires, corrosion, or loose connectors
    Interpretation: Visible wiring issues often correlate with high circuit voltage
  3. Measure voltage at solenoid connector with ignition ON (engine OFF)
    Expected: Voltage within OEM specified range (typically 12V reference)
    Interpretation: Voltage above specification supports high circuit fault
  4. Measure solenoid coil resistance with harness disconnected
    Expected: Resistance within manufacturer spec
    Interpretation: Out‑of‑range resistance indicates solenoid internal fault
  5. If wiring/solenoid tests normal, test ECM/PCM output and grounds
    Expected: Correct regulated voltage and ground continuity
    Interpretation: Abnormal readings indicate ECM/PCM issue

Repair Solutions

Replace intake valve control solenoid (Bank 2) medium
Estimated Cost: $150 - $350

OEM replacement recommended; ensure correct part for Bank 2

Repair or replace damaged wiring/connectors medium
Estimated Cost: $50 - $200

Depends on extent of wiring damage

Clean and secure electrical connections easy
Estimated Cost: $10 - $50

Use contact cleaner and dielectric grease

ECM/PCM inspection, update, or replacement hard
Estimated Cost: $800 - $1400

Rare; confirm other causes ruled out first

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Fuel rail pressure sensor circuit fault
  • General fuel delivery problem (fuel pump, filter)
