P2562 OBD-II Trouble Code: Turbocharger Boost Control Position Sensor Circuit

Check Engine Light

P2562 Code Definition

The P2562 code is a generic powertrain code related to vehicle speed control and the idle control system. It appears when the turbocharger boost control position sensor circuit has sent a reading to the engine control module outside of set parameters.

Codes related to the P2562 code include:

What the P2562 Code Means

Turbocharging is a type of forced air induction, which adds excessive amounts of air to increase vehicle horsepower. Turbochargers force the air and fuel into the combustion chambers, using the pressure from engine exhaust. The pressure moves impellers in two separate chambers (A and B). Elevated air pressure levels, called “boost pressure,” are specified based on manufacturer in a vehicle’s ECM.

If the ECM receives sensor input voltage signals that the pressure is higher or lower than the set allowed variances, typically under 9 pounds or more than 14 pounds, a P2562 code will be stored. When this happens, the ECM cannot effectively control boost levels.

What Causes the P2562 Code?

Several problems may cause a P2562 code including:

  • Damaged or defective wastegate solenoid (stuck in either the open or closed position)
  • Damaged or defective intercooler
  • Damaged or defective turbocharger boost sensor
  • Possible vacuum leak at the intake manifold
  • Damaged or leaking actuator
  • Other internal oil leaks that can (or have) damaged the turbo housing

What are the Symptoms of the P2562 Code?

Symptoms of a P2562 code may include:

  • Warning or Check Engine Light may illuminate
  • Decreased engine power
  • Unusual noises from the turbocharger or pipes
  • Darker or strange looking smoke from the exhaust
  • Increased engine temperature
  • Increased transmission temperature
  • “Hissing” noises from hoses or the wastegate
  • Possible cylinder detonation
  • High or unusual boost pressure levels

How Does a Mechanic Diagnose the P2562 Code?

A mechanic may use several methods to diagnose a P2562 trouble code, including:

  • Utilize an OBD-II scanner to check for a stored P2562 trouble code

  • Check for any engine misfire or knock codes, which may signify an alternate problem

  • Visually inspect the turbocharger for any damage, including hose clamps and the hoses themselves for leaks

  • Check for any give in the turbo housing

  • Check the boost pressure

  • Visually inspect the electrical wiring and connectors for any damage

  • Remove and test the wastegate

  • Check for oil in the turbo housing

  • Check for signs of damage in the turbo housing

  • Check for loose or damaged bearings

  • Check the vacuum with a vacuum gauge

  • Test turbocharger electrical circuitry

How Serious is the P2562 Code?

Due to the fact that a vehicle’s operation can be affected, this is considered a potentially serious issue. When this code appears, have your vehicle diagnosed and repaired as soon as possible to prevent further damage.

What Repairs can Fix the P2562 Code?

Several repairs can fix a P2562 trouble code and include:

  • Replace any damaged or leaking hoses and clamps related to the turbocharger system
  • Tighten any loose hoses
  • Tighten all nuts and bolts connecting the turbo to the intake flange
  • Repair or replace a damaged wastegate
  • Repair or replace any damaged or corroded wiring or connectors
  • Repair or replace damaged impellers
  • Repair or replace any loose or damaged bearings
  • Repair or replace a damaged or defective catalytic converter
  • Repair or replace the damaged or defective turbocharger
  • Clear all codes, test-drive the vehicle, and rescan to see if any codes reappear

Additional Comments for Consideration Regarding the P2562 Code

There have been technical service bulletins (TSBs) related to the P2562 code. It is recommended to always check for any related bulletins prior to any vehicle repairs.
