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
Internal short or failed coil can present high circuit voltage.
Chafed, corroded, loose, or shorted wires often cause high circuit voltage conditions.
Connector integrity affects voltage readings.
ECM supplying incorrect voltage or misinterpreting signal; rare but possible.
Some community sources misattribute P0083 to fuel rail pressure sensor circuit faults.
Diagnostic Steps
-
Connect a professional OBD‑II scanner and confirm P0083 on Bank 2Expected: Code P0083 present; note freeze frame and any related codesInterpretation: Verification of condition and context prior to electrical checks
-
Visually inspect wiring harness and connectors for damage or corrosionExpected: No exposed wires, corrosion, or loose connectorsInterpretation: Visible wiring issues often correlate with high circuit voltage
-
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
-
Measure solenoid coil resistance with harness disconnectedExpected: Resistance within manufacturer specInterpretation: Out‑of‑range resistance indicates solenoid internal fault
-
If wiring/solenoid tests normal, test ECM/PCM output and groundsExpected: Correct regulated voltage and ground continuityInterpretation: Abnormal readings indicate ECM/PCM issue
Repair Solutions
OEM replacement recommended; ensure correct part for Bank 2
Depends on extent of wiring damage
Use contact cleaner and dielectric grease
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)
