P0082: Intake Valve Control Solenoid Circuit Low (Bank 2)
Reduced engine performance, poor fuel economy, possible rough idle or hesitation
Overview
OBD-II P0082 Intake Valve Control Solenoid Circuit Low Bank 2 low voltage condition in intake valve control solenoid circuit affecting variable valve timing
Common Symptoms
- Check engine light illuminated
- Reduced engine power or performance
- Poor fuel economy
- Rough idle or hesitation
- Difficulty starting the engine
Most Common Causes
Internal electrical failure or mechanical degradation leading to low circuit voltage
Corroded, broken, or loose connectors causing low voltage circuit fault
Insufficient oil pressure affecting VVT system and solenoid operation
ECM internal regulator fault or corrupted calibration misreading normal voltage as low
Diagnostic Steps
-
Use professional OBD-II scanner to retrieve P0082 and any related codesExpected: Confirmation of code P0082 and note any additional codesInterpretation: Helps isolate whether other systems or codes are involved
-
Visually inspect intake valve control solenoid wiring and connectors (Bank 2)Expected: No damaged wires, corrosion, or loose connectorsInterpretation: Any damage may explain low circuit voltage
-
Measure voltage at the solenoid power lead with ignition onExpected: Voltage within manufacturer specification (approx 4.5–5V)Interpretation: Low voltage confirms circuit issue upstream of solenoid
-
Check resistance of the solenoid coil with multimeterExpected: Resistance within typical rangeInterpretation: Out-of-spec resistance indicates failed solenoid requiring replacement
-
Verify battery and charging system voltageExpected: Battery ~12.6V at rest; alternator output ~13.8–14.4VInterpretation: Low system voltage may mimic solenoid circuit faults
-
If wiring and solenoid are good, evaluate ECM output or reprogram calibrationExpected: Proper PWM signal and voltage reference from ECMInterpretation: Lack of correct signal suggests ECM fault or calibration issue
Repair Solutions
Part and labor vary by vehicle; confirm OEM specifications
Cost depends on extent of wiring harness damage
Useful if oil condition contributing to VVT issues
Considered after confirming other components are good
Common Misdiagnoses
Avoid these common diagnostic mistakes:
- Confusing P0082 with fuel rail pressure codes (e.g., P0087)
- Assuming only sensor fault without checking wiring or ECM output
