P006F: Turbo/Supercharger Boost Control Supply Voltage High
Code P006F indicates that the Engine Control Module (ECM) has detected a voltage higher than expected on the boost control solenoid supply circuit. This circuit provides power to the solenoid that regulates boost pressure. High voltage can result from a short to power, faulty wiring, or a defective solenoid. The ECM monitors this voltage to ensure proper boost control; an out-of-range reading triggers the code and may cause the ECM to limit boost or enter fail-safe mode.
01. Most Common Causes
- Short to power in the boost control solenoid circuit
- Faulty boost control solenoid
- Damaged wiring or connector
- Corroded terminals
- ECM internal fault (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine power or limp mode
- Poor acceleration
- Possible overboost or underboost conditions
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to confirm P006F and check for related codes.
Step 2: Visually inspect the boost control solenoid wiring and connector for damage, corrosion, or shorts.
Step 3: Measure voltage at the solenoid connector with key on; should be battery voltage (12-14V). If higher, trace short to power.
Step 4: Test the solenoid resistance with a multimeter; compare to manufacturer specs.
Step 5: If wiring and solenoid are okay, check for ECM issues by testing circuit continuity and voltage at ECM connector.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended. The vehicle may enter limp mode, reducing power and potentially causing unsafe driving conditions. Have it diagnosed promptly.
How much does it cost to fix?▼
Typically $50-$150 for parts and labor, depending on the cause. A new boost control solenoid costs around $30-$80, plus diagnostic time.
