P0244
Turbocharger/Supercharger Wastegate Solenoid A Range/Performance
If your code reader dashboard displays the generic DTC error code P0244, your vehicle is currently experiencing an active failure related to "Turbocharger/Supercharger Wastegate Solenoid A Range/Performance". Proper system troubleshooting is required to safely clear this warning.
Driver's Summary
The diagnostic trouble code P0244 indicates an active fault in the turbocharger/supercharger wastegate solenoid a range/performance circuit or component. Typical symptoms include erratic boost levels, engine surging, limp mode. This is a serious fault — avoid extended driving and have your vehicle inspected by a mechanic as soon as possible to prevent further damage.
Symptoms
Erratic boost levels, engine surging, limp mode
Common Causes
- Failed wastegate control solenoid
- Torn wastegate actuator diaphragm
- Clogged vacuum lines to solenoid
- Damaged wiring circuit
How to Fix
- 1 Replace wastegate solenoid
- 2 Test and replace wastegate actuator
- 3 Clear or replace vacuum lines
- 4 Repair solenoid wiring
Technical Explanation
Code P0244 is confirmed when the ECM's diagnostic algorithm detects a parameter deviation that persists across a defined number of consecutive drive cycles. For injector-specific codes, the ECM monitors the injector control circuit voltage drop during each pulse; a shorted or open injector presents a characteristic resistance signature that differs measurably from a healthy unit. The fault remains stored in memory even after the MIL is cleared; it becomes a confirmed DTC after failing two consecutive drive cycles, and the PCM logs a freeze frame record of the engine's exact operating state at the moment of detection.
Is It Safe to Drive?
With P0244 active, your engine or transmission is not operating within design parameters. Short-term driving may seem fine, but internal damage is accumulating — particularly to failed wastegate control solenoid.
Mechanic's Pro Tip
For P0244, test the solenoid's coil resistance with a multimeter before ordering parts — most solenoids should read between 14 and 40 ohms; an open (infinite resistance) or short (near zero) confirms it's failed electrically. Also verify the PCM is commanding the solenoid by backprobing the connector with a test light during the relevant operating condition — if there's no command signal, the fault is in the PCM or wiring, not the solenoid itself.
