P0082 — Intake Valve Control Solenoid Circuit Low (Bank 2)

Severity: medium Drive with care, to a shop

What P0082 means

The engine control module drives a solenoid that adjusts variable valve timing on the bank 2 intake side and monitors the voltage in its circuit. P0082 sets when that voltage stays lower than expected, for example from a short to ground or a poor connection. Without proper control of valve timing, the engine loses performance and efficiency.

Symptoms

  • Check Engine light on
  • Reduced power and sluggish acceleration
  • Worse fuel economy
  • Rough idle or hesitation
  • Hard starting
  • Possible limp mode

Possible causes

  1. Faulty bank 2 intake valve control solenoid
  2. Damaged wiring harness or poor connector contact
  3. Control wire shorted to ground
  4. Low, dirty or incorrect engine oil
  5. ECM driver fault or software issue
  6. Corroded or damaged solenoid connector pins

How to diagnose

  1. Scan all codes and freeze frame data, and look for other valve timing codes.
  2. Check oil level, condition and viscosity against the manufacturer spec.
  3. Inspect the bank 2 solenoid connector and wiring for chafing, oil contamination, corrosion and loose pins.
  4. Measure the solenoid coil resistance and compare it to the service manual spec.
  5. Check power and control signal at the connector and test the signal wire for a short to ground.
  6. Run a scan tool actuator test and see whether the solenoid responds.
  7. If wiring and solenoid test good, evaluate the ECM and check for a software update.

Common fixes

  • Replace the bank 2 intake valve control solenoid
  • Repair wiring or replace a damaged connector
  • Change the oil and filter with the correct grade
  • Reflash or replace the ECM if confirmed faulty

Questions and answers

What does P0082 mean?

It means low voltage in the circuit of the solenoid that controls intake valve timing on bank 2. The module cannot control the system correctly, so the check engine light comes on.

Can I drive with P0082?

Often for a short time if the car runs acceptably, but don't put off repair. You may see power loss, higher fuel use and extra wear if oil is part of the problem.

Can oil cause P0082?

Poor or low oil can affect variable valve timing, but a low-voltage circuit code more often points to wiring or the solenoid itself.

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.
