Intake Valve Control Solenoid Circuit Low (Bank 2)
P0082 indicates the intake valve control solenoid circuit on Bank 2 is detecting a low voltage condition. This solenoid controls variable valve timing and when it malfunctions, the engine cannot properly adjust valve timing, affecting performance and emissions.
What You Might Notice
- Check engine light illuminated
- Poor acceleration and sluggish throttle response
- Decreased fuel economy
- Rough idle or engine hesitation
- Potential difficulty starting in cold conditions
Most Common Causes
- 1
Wire harness shorted to ground
The wiring between the PCM and solenoid is damaged or corroded, creating an unintended ground connection. This causes the circuit voltage to drop below acceptable levels.
- 2
Faulty intake valve control solenoid
The solenoid coil has failed internally or the solenoid is shorted to ground, preventing proper circuit voltage and current flow.
- 3
Poor electrical connection or corrosion
Corroded connector pins or loose connections at the solenoid or PCM reduce circuit voltage and cause intermittent or continuous low voltage signals.
- 4
Faulty PCM or ECM
The engine control module has failed or its solenoid driver circuit is malfunctioning, unable to properly supply voltage to the solenoid.
How to Diagnose It
- 1
Check Wire harness shorted to ground — The wiring between the PCM and solenoid is damaged or corroded, creating an unintended ground connection. This causes the circuit voltage to drop below acceptable levels.
- 2
Check Faulty intake valve control solenoid — The solenoid coil has failed internally or the solenoid is shorted to ground, preventing proper circuit voltage and current flow.
- 3
Check Poor electrical connection or corrosion — Corroded connector pins or loose connections at the solenoid or PCM reduce circuit voltage and cause intermittent or continuous low voltage signals.
- 4
Check Faulty PCM or ECM — The engine control module has failed or its solenoid driver circuit is malfunctioning, unable to properly supply voltage to the solenoid.
How to Fix It
- 1
Inspect and repair wiring harness
Disconnect the PCM and solenoid connectors. Using a wiring diagram, locate and inspect the control wires for damage, corrosion, or shorts to ground. Repair or replace damaged sections of the harness.
- 2
Clean or replace solenoid connectors
Remove corrosion and oxidation from connector pins using electrical contact cleaner and a soft brush. If pins are severely damaged, replace the connector terminal set.
- 3
Replace intake valve control solenoid
If testing confirms the solenoid is faulty or shorted, remove and install a new solenoid assembly. Torque all fasteners according to manufacturer specifications.
- 4
Reprogram or replace PCM/ECM
If wiring and solenoid test normal, the PCM/ECM may require reprogramming or replacement. Have a professional programmer or dealer reprogram the module, or replace if damaged.
