Encountering a 'Check Engine' light on your dashboard can be a source of immediate concern for any vehicle owner. While numerous diagnostic trouble codes (DTCs) can trigger this warning, the P0244 code often points to a specific issue within your vehicle's turbocharger or supercharger system. This code, officially known as "Turbocharger Wastegate Solenoid A Range/Performance," indicates that your vehicle's Powertrain Control Module (PCM) has detected an anomaly in the operation of the wastegate solenoid.
What Exactly is the P0244 Code?
The P0244 code signifies a problem with the "Turbocharger Wastegate Solenoid A Range/Performance." In essence, it means that the engine's computer (ECM/PCM) has identified that the wastegate solenoid's input circuit range or its performance is outside the manufacturer's specified parameters. This assessment is typically made by comparing the solenoid's readings against data from other critical sensors, such as the turbo boost sensor, manifold absolute pressure (MAP) sensor, or the barometric pressure (BARO) sensor, particularly when the engine is idling.
The wastegate is a critical component in turbocharged and supercharged engines. Its primary function is to regulate the boost pressure produced by the turbocharger or supercharger. When the engine requires less boost, the wastegate opens to divert exhaust gases away from the turbine, preventing overboost conditions that could damage the engine. The wastegate solenoid is an electronic valve that controls the wastegate's operation.
Common Causes Behind the P0244 Code
| Cause | Description | Likelihood |
|---|---|---|
| Wastegate Solenoid Failure | Solenoid sticking open, closed, or failing to respond correctly | High |
| Wiring Issues | Frayed wires, loose connections, corrosion, or short circuits | Medium |
| Vacuum Leaks | Leaks in vacuum lines or blockages preventing proper operation | Medium |
| Sticking Wastegate Valve | Mechanical valve binding due to carbon buildup or damage | Medium |
| PCM Malfunction | Faulty powertrain control module sending incorrect signals | Low |
Recognizing the Symptoms of P0244
🚨 Primary Symptoms:
Illuminated Check Engine Light - The most obvious indicator
Lack of Turbo/Supercharger Boost - Reduced engine power during acceleration
Erratic Engine Turbo Boost - Inconsistent power delivery
Rough Idling or Stalling - Engine running roughly at idle
Reduced Fuel Efficiency - Increased fuel consumption
Unusual Noises - Hissing, whistling, or rattling from engine bay

Real-World User Examples
Sarah's Daily Commuter Fix
Sarah noticed her 2015 Ford EcoBoost felt sluggish during her morning commute. Using her iCarsoft CR-MAX BT, she quickly identified the P0244 code and discovered through live data monitoring that boost pressure was significantly lower than commanded. A visual inspection revealed a cracked vacuum line to the wastegate actuator. A simple $15 vacuum line replacement and code clearing with her CR-MAX BT restored her car's performance completely.
Mark's Overboost Prevention
Mark's 2017 Subaru WRX suddenly lost power and started running rough at idle during a spirited drive. The P0244 code appeared, and he was concerned about potential engine damage. His iCarsoft CR-MAX BT showed erratic boost pressure readings through live data streaming. After replacing the faulty wastegate solenoid, the CR-MAX BT confirmed stable boost pressure readings, preventing costly engine damage.
David's Persistent Problem Solution
David battled a recurring P0244 code on his 2013 Mercedes C-Class despite replacing the wastegate solenoid. Using the iCarsoft CR-MAX BT's advanced diagnostic capabilities, he monitored electrical parameters and discovered intermittent voltage drops. Further investigation revealed a corroded connector pin in the engine harness. Cleaning the connection finally resolved the persistent issue, saving him a costly dealership visit.
Frequently Asked Questions (FAQ)
Yes, P0244 can be serious. While you might be able to drive your car, it's not recommended for extended periods. The code indicates an issue with boost regulation, which can lead to reduced engine performance, increased fuel consumption, and potentially more severe engine damage if left unaddressed. It's best to diagnose and fix it as soon as possible.
P0244 typically refers to a range/performance issue with the wastegate solenoid circuit. P0245 (Turbocharger Wastegate Solenoid A Low) and P0246 (Turbocharger Wastegate Solenoid A High) usually indicate an electrical circuit issue where the voltage is either too low or too high, respectively. While related, P0244 is more about the functional performance being out of spec rather than a direct electrical short or open circuit.
The cost to fix a P0244 code varies widely depending on the underlying cause, your vehicle's make and model, and whether you do it yourself or take it to a mechanic. A simple vacuum line replacement might cost very little, while a new wastegate solenoid can range from $100-$300 for the part, plus labor. Using a diagnostic tool like the iCarsoft CR-MAX BT can save you money by accurately identifying the problem, potentially avoiding unnecessary parts replacements.
The iCarsoft CR-MAX BT is invaluable for P0244 diagnosis. It allows you to read and clear the P0244 code and freeze frame data, monitor live data streams (boost pressure, wastegate solenoid command, etc.) to pinpoint performance issues, perform OE-level full system diagnostics to check for related codes, and verify repairs by monitoring system performance after fixes. Its user-friendly interface and comprehensive vehicle coverage make it ideal for both DIY enthusiasts and professional mechanics.
While a dirty air filter can restrict airflow and affect engine performance, it's unlikely to directly cause a P0244 code. P0244 specifically points to the wastegate solenoid's range or performance. However, a severely restricted air filter could indirectly impact boost pressure, which might influence the wastegate's operation. It's always good practice to ensure your air filter is clean.
Yes, with an OBD-II scanner like the iCarsoft CR-MAX BT, you can clear the P0244 code. However, simply clearing the code without addressing the underlying issue will only result in the code reappearing. It's crucial to diagnose and fix the problem first before clearing the code.
