P0245 Code: Turbocharger/Supercharger Wastegate Solenoid “A” Low

If your OBD scan tool retrieved a P0245 code, it’s pointing to a problem in your turbocharger/supercharger wastegate solenoid. This solenoid is responsible for controlling your turbocharger/supercharger’s wastegate valve so that it can reduce the boost pressure of the air flowing to the engine. Read on to learn more about what the P0245 error code means. 

What Does a P0245 Code Mean? 

Diagnostic trouble code (DTC) P0245 stands for “Turbocharger/Supercharger Wastegate Solenoid “A” Low.” 

Vehicles with a turbocharger have a wastegate valve that allows the boost control system to adjust the boost pressure in the engine. The wastegate valve opens when there’s a need to lower boost pressure. This is crucial because an overboost condition can damage the engine.

In modern vehicles, the powertrain control module (PCM) controls the wastegate operation. The PCM monitors the signal from the turbocharger/supercharger wastegate solenoid in the “A” position regularly. It provides a power supply or a ground to the wastegate solenoid to energize it. Once the PCM detects a problem with the solenoid or its circuit, it’ll trigger the P0245 code.

Your vehicle’s PCM might also disable your turbocharger to prevent the risk of overboosting and further damaging the boost pressure system. This code usually points to an electrical fault.

Note: The definition of code P0245 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

What are the Common Causes of the P0245 Code?

• Bad wastegate solenoid
• Faulty wiring
• Defective PCM

What are the Common Symptoms of the P0245 Code?

• Illuminated check engine light
• Lack of boost from the turbocharger/supercharger
• Vehicle stuck in “limp” mode

How to Diagnose the P0245 Code

DTC P0245 is a generic trouble code. However, the steps for diagnosing this code will vary depending on the specific vehicle that you own. If you don’t have the DIY experience to get the job done, it’s best to take your vehicle to an auto repair shop.
