What Does P006E Mean?
The ECM has detected that the supply voltage to the turbocharger/supercharger boost control "A" solenoid circuit is below the expected threshold. This solenoid controls the primary wastegate or bypass valve that regulates turbo boost pressure. Without proper supply voltage, the solenoid cannot actuate, leaving boost control to mechanical spring pressure only. The driver may experience reduced or uncontrolled boost, loss of power, or limp mode activation.
Common Causes
35%
Damaged or corroded wiring/connector in the boost control 'A' supply circuit
25%
Failed boost control solenoid with open or degraded coil
20%
Blown fuse or faulty relay in the boost control supply circuit
12%
Poor ground connection for the boost control circuit
8%
ECM/PCM internal driver circuit failure
Diagnostic Steps
1
Check the boost control circuit fuse in the underhood fuse box. This is the most common cause of supply voltage loss. If blown, test for shorts before replacing.
2
Measure supply voltage at the boost control 'A' solenoid connector with key on engine off. Should be battery voltage (12.0-14.5V). Below 10V indicates a supply-side issue.
3
Disconnect the solenoid and measure coil resistance (typically 10-30 ohms). An open circuit or very high resistance indicates a failed solenoid coil.
4
Inspect the wiring from the fuse box to the solenoid. Focus on areas near the turbocharger and exhaust where extreme heat can damage insulation and create opens or high-resistance connections.
5
Check ground continuity from the solenoid connector ground pin back to the ECM ground reference. Should be under 0.5 ohms.

The most common cause of P006E (Turbocharger/Supercharger Boost Control "A" Supply Voltage Circuit Low) is: Damaged or corroded wiring/connector in the boost control 'A' supply circuit
Typical repair costs for P006E range from $100 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive at reduced power. The vehicle will likely enter limp mode, limiting boost pressure and speed. Without electronic boost control, the wastegate operates on spring pressure alone, which provides a basic level of over-boost protection. Avoid heavy load situations. Repair within 1-2 weeks.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P006E to identify the root cause.
