Turbocharger/Supercharger Wastegate Solenoid A Intermittent
What does P0244 mean?
The P0244 code means the vehicle's onboard diagnostic system has detected: Turbocharger/Supercharger Wastegate Solenoid A Intermittent. This is a moderate severity code.
Common Symptoms
- Boost pressure fluctuates unpredictably
- Check Engine Light comes on intermittently
- Occasional limp mode activation
- Sporadic loss of power during acceleration
- Inconsistent turbo performance
Probable Causes (Ranked by Likelihood)
- Loose or corroded wastegate solenoid connector Very High
- Intermittent break in solenoid wiring harness High
- Wastegate solenoid with intermittent internal coil failure High
- Heat-damaged wiring near turbocharger Moderate
- PCM intermittent driver circuit fault Low
Step-by-Step Diagnostic Procedure
-
Perform a wiggle test on the solenoid connector and wiring while monitoring boost pressure with a scan tool
-
Check solenoid resistance when cold and after the engine is at operating temperature -- intermittent coils often fail when hot
-
Inspect wiring harness near the turbocharger for heat damage, melted insulation, or chafed wires
-
Monitor the PCM wastegate duty cycle during a road test for erratic signal drops
-
Replace the solenoid and repair any damaged wiring found during inspection
Frequently Asked Questions
Can I drive with code P0244?
You can drive short distances with caution. The intermittent nature means boost control is unpredictable, and the vehicle may suddenly enter limp mode during driving.
Why is an intermittent code harder to diagnose?
The fault only occurs under certain conditions like heat, vibration, or specific engine loads. Standard testing in the shop may not reproduce the problem, requiring extended monitoring or road testing.
Can heat from the turbo damage the solenoid wiring?
Yes. Turbochargers generate extreme heat that can melt or degrade nearby wiring insulation over time. This is one of the most common causes of intermittent wastegate solenoid codes.
