P0082 OBD-II Trouble Code: Intake Valve Control Solenoid Circuit Low (Bank 2)

P0082 trouble code definition

P0082 indicates a fault within the intake valve control solenoid circuit. It may be seen with P0081. The car may have a bank 1 and bank 2 solenoids

What the P0082 code means

P0082 is a OBD2 code that is specific to the bank 2 intake valve control solenoid. The variable valve timing system has the ECM send a signal to try to control the intake valve control solenoid and has found solenoid performance to be out of range.

This sets a Check Engine Light on the dash and puts the vehicle into a failsafe mode. In addition, the variable valve timing system is disabled until the the intake valve solenoid bank 2 proper range is detected.

What causes the P0082 code?

  • Failed intake valve control solenoid bank 2
  • Open or short in solenoid wiring harness
  • Faulty ECM
  • Loose or poor electrical connection

What are the symptoms of the P0082 code?

  • The engine control module will detect low voltage in the bank 2 control solenoid and this causes a Check Engine Light to be displayed on the dashboard.

  • The ECM also puts the vehicle into a failsafe mode to protect the car and prevent damage. This failsafe mode disables the variable valve timing system causing a felt lack of power in acceleration and lowers fuel economy.

How does a mechanic diagnose the P0082 code?

  • A qualified mechanic will be begin by hooking up a scan tool into the vehicle's OBD2 port and checking for any codes present. Each code will have its own freeze frame data telling us under what conditions such as engine speed, load, coolant temperature, vehicle speed that the fault was detected at.

  • The code will then be cleared and a test drive performed. On the test drive the technician will do their best to follow the same conditions noted in the freeze frame data.

  • If the code comes back on a visual inspection will be needed. The visual inspection will look at all the wiring for the control solenoid harness and all connectors and the solenoid itself.

  • If the visual inspection is passed, a scan tool will be used to monitor live data on the solenoid and its operation.

  • If the solenoid is operating properly then the ECM will need to be tested by following a manufacturer specific test process.

Common mistakes when diagnosing the P0082 code

In general P0082 is a easy code to diagnose properly. In some scenarios the fault may only be found intermittently and seems to occur randomly. For both circumstances all steps must be followed in the proper order and no steps should be skipped.

Most of the time the solenoid is the cause of the fault but never make assumptions and test the solenoid for proper operation before condemning it.

How serious is the P0082 code?

Any code that initiates a failsafe mode should be taken care of as soon as possible to prevent damage to the vehicle and to ensure safe driving. With P0082 disabling the variable valve timing, driveability may change when compared to normal operation.

The car should have no trouble getting to a safe location or repair facility after the code is displayed on the dash.

What repairs can fix the P0082 code?

  • Replacing ECM
  • Repairing or replacing the wiring harness
  • Repairing connection issues
  • Replacing the bank 2 intake valve control solenoid

Additional comments for consideration regarding the P0082 code

It is not unusual to have intermittent codes present on higher mileage cars. In some cases the issue may be hard to track down without proper diagnosis and a qualified mechanic.

In cars equipped with variable valve timing the intake valve control solenoid is an important piece that is needed for proper operation of the valve timing system. Variable valve timing adds or pulls timing as needed by the ECM. This allows quicker acceleration when needed and improves fuel economy.

A scan tool will be needed to test for proper solenoid operation. These scan tools allow technicians to view live data from the solenoid such as ohms, voltage, and on/off operation. This information allows technicians to make an informed diagnosis instead of simply guessing.

P0082 will only be seen on vehicles with multiple engine banks such as V6 and V8 engines. The bank 2 is typically found on the passenger side of the engine block. The intake valve control solenoid is normally found near the intake portion of the engine cylinder head.
