P0082 — Intake Valve Control Solenoid Circuit Low Bank 2

Generic OBD-II · all makesPowertrain (engine & transmission)

P0082 indicates that the Powertrain Control Module (PCM) has detected a low voltage condition in the intake valve control solenoid circuit for bank 2. This typically means the solenoid is not receiving enough voltage to operate properly.

Symptoms

What causes it — most likely first

1. Faulty intake valve control solenoid (bank 2)

The solenoid may have an internal short or open circuit that prevents it from drawing the proper voltage.

2. Wiring harness damage or poor connections

Corroded pins, broken wires, or loose connectors in the solenoid circuit can cause a voltage drop.

3. Blown or weak fuse/relay for the intake valve control circuit

A partially failed fuse or a faulty relay may allow insufficient voltage to reach the solenoid.

4. Ground circuit problem for bank 2 solenoid

A high‑resistance ground path can cause the PCM to read a low voltage condition.

5. PCM internal voltage regulation fault (rare)

Only after ruling out the solenoid, wiring, fuses, and grounds should the PCM be considered, as internal regulator failures are uncommon.

How it's diagnosed

  1. Verify the Check Engine Light code and confirm that P0082 is present with no other conflicting codes.
  2. Inspect the solenoid connector for corrosion, looseness, or damaged pins; clean and reseat if necessary.
  3. Measure voltage at the solenoid supply wire with the ignition on; it should be close to battery voltage (≈12 V).
  4. Check continuity and resistance of the solenoid coil and wiring back to the PCM; compare to service specifications.
  5. Test the related fuse and relay for proper operation; replace if out of spec.
  6. If all component tests are within spec, perform a PCM voltage output test or swap with a known good PCM to confirm.

Frequently asked

Can the PCM be the cause of a P0082 code?

It is possible but rare. Most P0082 cases are caused by a faulty solenoid, wiring, or related fuse/relay. Replacing the PCM should be a last resort after all other possibilities have been ruled out.

Will a bad intake valve control solenoid cause the engine to run poorly even if the Check Engine Light is not on?

Yes, a failing solenoid can cause intermittent low voltage conditions that affect valve timing, leading to rough idle or loss of power before the PCM logs a permanent code.

Is it necessary to replace the entire wiring harness for this code?

Usually not. Most wiring issues are localized to a connector or a short section of wire. Repair or replace only the damaged portion after thorough inspection.

Should I clear the code after fixing the problem, or let the PCM re‑learn automatically?

After correcting the fault, clear the code with a scan tool. The PCM will then monitor the circuit and set the code again only if the problem persists.
