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:
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.
Several problems may cause a P2562 code including:
Symptoms of a P2562 code may include:
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
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.
Several repairs can fix a P2562 trouble code and include:
