What it means

P0083 is the generic code for a high signal in the intake valve control solenoid circuit on Bank 2, the side of the engine without cylinder number one. The engine control unit drives the solenoid for variable intake valve timing or lift and monitors the circuit. It set the code because the voltage or current was higher than expected, which points to a short to voltage, a fault in the driver or a faulty solenoid.

Symptoms

  • Engine warning light on
  • Rough idle or uneven running
  • Reduced power or poor acceleration
  • Poor fuel economy
  • Hesitation or stumbling at certain engine speeds
  • Engine may enter a limited performance mode

Possible causes

  • Intake valve control solenoid on Bank 2 faulty internally, for example a shorted or damaged coillikely
  • Wiring to the solenoid shorted to a voltage supply, chafed or damagedlikely
  • Corroded, loose or contaminated connector at the solenoid or control unitpossible
  • Poor earth or supply fault affecting the solenoid circuitpossible
  • Oil contamination or very dirty oil affecting the solenoid and its wiringpossible
  • Fault in the solenoid driver inside the engine control unitrare
  • Outdated control unit software where the manufacturer has issued a known correctionrare

How to diagnose

  1. Read all stored and pending codes and the freeze frame data to see engine speed, load and temperature when the fault set, and note any related valve timing codes.
  2. Check the engine oil level and condition, as the system relies on clean oil at the correct level.
  3. Inspect the Bank 2 solenoid wiring and connector for chafing, heat damage, oil ingress, corrosion and bent or pushed-back pins.
  4. Measure the solenoid coil resistance and compare it with the manufacturer's specification for your model and engine.
  5. Check the supply voltage and earth at the solenoid connector with the ignition on, following the wiring diagram for the engine.
  6. Test the wiring between the solenoid and control unit for a short to voltage and for continuity.
  7. Use a scan tool to command the solenoid if the vehicle supports it and watch whether the circuit and valve timing respond.
  8. Check for any applicable software updates or technical service bulletins for the model once the wiring and solenoid test good.

How to fix

  • Replace the Bank 2 intake valve control solenoid if its resistance or operation is out of specification.
  • Repair or replace damaged wiring, correcting any short to voltage.
  • Clean, repair or replace a corroded or damaged connector and terminals.
  • Restore a faulty supply or earth connection.
  • Change the oil and filter to the correct specification if the oil is dirty or contaminated.
  • Update the control unit software only if a known fault is documented, or replace the control unit if the driver is proven faulty.

Can I keep driving?

Medium severity

The car can usually be driven short distances, but have it checked soon because performance and economy may suffer. Avoid heavy loads or long trips, and stop if the engine runs very roughly or loses power badly.
