P0244
HighP0244 — Turbocharger Wastegate Solenoid A Range/Performance (Bank
Description
What the Code Means
P0244 flags incorrect operation of the turbocharger wastegate control solenoid (circuit A). Normally the solenoid meters vacuum to the wastegate actuator, which opens the bypass port to cap boost pressure. If the solenoid sticks closed, the wastegate stays shut and boost climbs unchecked — overboost.
The cause can be mechanical sticking of the solenoid itself or a vacuum leak in the control circuit.
Symptoms
Symptoms
- Overboost — boost pressure exceeds the target value;
- Check Engine light on the instrument cluster;
- reduced engine power;
- surging and pulsing in thrust.
Causes and fixes
Diagnosis and Repair
- Read the fault codes with a scanner.
- Check the solenoid for sticking; tap it gently to free it.
- Check the vacuum lines to the solenoid and to the wastegate actuator for leaks.
- Test solenoid operation with a diagnostic scanner (actuator activation).
- If the solenoid is stuck, replace it with a new one, OEM part number
11657588856.
Possible secondary damage
Secondary Problems
- Overboost causes engine knock and potential damage to the pistons and turbocharger;
- prolonged overboost can also destroy the catalytic converter.
Don't put off the repair: the longer the engine runs in overboost, the higher the risk of costly damage to the piston assembly, turbo, and exhaust.
