P0082🔧 Variable valve timing (intake camshaft oil control solenoid)Stop and fix promptly

P0082: Intake Valve Control Solenoid Circuit Low Bank 2 (Meaning, Causes, Fixes)

Reviewed 2026-10-24 · Based on 2 cited source(s)

What P0082 means

On engines with variable valve timing, the engine computer (ECM/PCM) moves the camshaft by sending engine oil through a control solenoid. OBD-Codes.com explains that the computer drives this solenoid with a pulse width modulated (PWM) signal and watches that signal; if the voltage is below specification, it sets P0082 and turns on the check engine light. Bank 2 is the side of the engine that does not have cylinder number 1 (verify for your engine), so P0082 only applies to V-type and other engines with two cylinder banks. OBD-Codes.com says the intake valve control solenoid is usually on the intake manifold side of the cylinder head. It is a generic code that applies to all makes from 1996 on, though repair steps vary by model. RepairPal defines P0082 as Intake Valve Control Solenoid Circuit Low and describes a solenoid that uses oil pressure to let the PCM adjust valve timing, with the code set when the PCM finds an issue with the solenoid's signal. The sources differ in a few ways. OBD-Codes.com describes an electrical fault, a short to ground in the wiring or the solenoid, while RepairPal lists engine oil problems among the common causes and an oil and filter change as the common repair. RepairPal's description and cause list also say 'exhaust valve' even though the code and its title are about the intake solenoid, and its title leaves out the bank. RepairPal's severity (Urgent) and its 'engine may not start' symptom are stronger than anything OBD-Codes.com lists. OBD-Codes.com says this code is similar to P0081 and P0083 and may be accompanied by P0028; it is the bank 2 match for P0076.

Severity: can I keep driving?

Stop and fix promptly

Get it checked soon and avoid hard driving until then. RepairPal rates P0082 Urgent, meaning immediate action is needed, and lists decreased engine performance, higher fuel use and, in some cases, an engine that may not start. OBD-Codes.com gives no severity rating and lists milder symptoms: the check engine light, poor acceleration and lower fuel economy. Check your engine oil level right away, since RepairPal lists low or wrong-spec oil among the causes.

Common symptoms

Likely causes

Roughly most to least common, based on the sources below. Your vehicle may differ.

  1. Wiring harness shorted to ground (OBD-Codes.com), or another wiring issue (RepairPal)
  2. Intake valve control solenoid shorted to ground internally (OBD-Codes.com); RepairPal lists a failed solenoid but calls it the exhaust valve control solenoid
  3. Engine oil level too low (RepairPal only)
  4. Engine oil that doesn't meet the manufacturer's requirements (RepairPal only)
  5. Faulty engine computer (ECM/PCM) (OBD-Codes.com, RepairPal)

Diagnostic steps you can do

⚠ Before you start

Work on a cool engine, parked on level ground with the parking brake set. Never work under a car supported only by a jack.

  1. Check the engine oil level and make sure the oil matches your owner's manual spec; RepairPal lists low or wrong oil as common causes and an oil and filter change as the common repair.
  2. Find the bank 2 intake valve control solenoid, usually on the intake side of the cylinder head on the bank without cylinder 1, and look for chafed wires touching metal, damaged insulation or corroded connectors, since a low-circuit code usually points to a short to ground.
  3. OBD-Codes.com notes the solenoid can be switched on its power side or its ground side depending on the vehicle, so check a factory wiring diagram to see how your circuit works before testing.
  4. With the computer unplugged, OBD-Codes.com describes putting the meter's positive lead on battery positive and the negative lead on each solenoid wire to look for a short to ground. If you find one, unplug connectors one at a time and work back toward the solenoid to locate it.
  5. To check the solenoid itself, measure resistance from each solenoid terminal to a known good ground. OBD-Codes.com says low resistance to ground means the solenoid may be shorted internally.
  6. If wiring and solenoid test good, OBD-Codes.com suggests comparing the duty cycle commanded on an advanced scan tool with the actual signal at the solenoid using an oscilloscope or graphing multimeter at different engine speeds and loads. No signal from the computer may mean a computer fault.

Typical fixes

Repair costs vary widely by vehicle, region, parts brand and shop, so we don't quote prices. Get a written estimate after diagnosis.

🛠 When to call a pro

  • The engine won't start or runs poorly along with the code
  • You don't have a wiring diagram, multimeter or a scan tool that shows solenoid duty cycle
  • The code returns after an oil change and a wiring repair or new solenoid
  • Other camshaft timing codes such as P0028 or P0081 are also set
  • Tests point to the engine computer, which may need programming to your vehicle

FAQs

Can I drive with P0082?

Only carefully and for a short time. RepairPal rates it Urgent and says the engine may lose performance or even fail to start, while OBD-Codes.com lists poor acceleration and lower fuel economy. Check the oil level first and get it diagnosed soon.

What is the difference between P0076 and P0082?

Both mean the intake valve timing control solenoid circuit voltage is low. P0076 is bank 1, the side with cylinder number 1, and P0082 is bank 2, the other side, so P0082 only shows up on engines with two cylinder banks such as a V6 or V8.

What does 'circuit low' mean in P0082?

OBD-Codes.com says the computer saw the solenoid signal voltage below specification, and its listed causes are a wiring harness or solenoid shorted to ground, or a faulty computer.

How much does it cost to fix P0082?

Neither source gives a repair cost for P0082. It can be as simple as an oil change or a chafed wire, or it may need a new solenoid, so diagnose it before buying parts.
