Turbo Wastegate Solenoid A Range/Performance
The P0244 code indicates that the Engine Control Module (ECM) has detected a performance or range issue with the turbocharger wastegate solenoid 'A'. This solenoid controls the boost pressure by regulating the vacuum or pressure to the wastegate actuator. When the actual boost pressure does not match the desired boost pressure within a specified range, the ECM sets this code. Common causes include a faulty solenoid, vacuum leaks, wiring issues, or a stuck wastegate.
01. Most Common Causes
- Faulty turbocharger wastegate solenoid A
- Vacuum or boost leak in the wastegate control system
- Wiring or connector issues to the solenoid
- Stuck or malfunctioning wastegate actuator
- Carbon buildup on wastegate components
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine power or boost
- Poor acceleration
- Possible overboost or underboost condition
- Hissing noise from turbo area
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect wastegate solenoid, vacuum lines, and wiring for damage or disconnection.
Step 3: Test solenoid resistance and operation using a multimeter and vacuum pump.
Step 4: Check for boost leaks using a smoke machine or boost leak tester.
Step 5: Verify wastegate actuator movement and linkage operation.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as reduced engine power and potential overboost can cause engine damage. Have it diagnosed promptly.
How much does it cost to fix?▼
Repair costs typically range from $50 to $150 for a solenoid replacement, but can be higher if there are additional issues like vacuum lines or wiring repairs.
