P006E
Turbocharger/Supercharger Boost Control A Supply Voltage Circuit Low
Turbo / boost control
Generic OBD-II
High
What it means
P006E means the supply voltage feeding the turbo or supercharger boost control circuit has dropped too low. It usually points to a wiring, connector, ground or fuse problem on the power feed rather than the boost hardware itself. The engine keeps running, but with the boost control unpowered it often falls back to a reduced-power limp mode until the supply fault is repaired.
High
Can I keep driving? Driveable, but boost control loses its supply voltage and the engine may enter reduced-power limp mode; repair before hard driving.
Common symptoms
What you'll notice
- Check-engine light on
- Lack of power or turbo lag
- Reduced-power (limp) mode
Common causes
Most likely first
- Open or shorted supply-voltage wiring to the boost control circuitLikely
- Poor electrical connection or corroded connectorCommon
- Blown fuse or bad ground on the supply feedCommon
- Faulty boost control solenoid/moduleLess often
- Failed ECM (least likely)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data, then check the supply-voltage feed to the boost control circuit for an open, short or blown fuse.
- Inspect the connector and grounds for corrosion or looseness and confirm voltage at the solenoid with the key on.
- Measure the boost control solenoid resistance; replace it if out of spec.
- Consider the ECM only after the supply circuit and solenoid test good. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P006E?+
Briefly, but without a proper supply voltage the boost system may be disabled and the engine limited in power, so fix it soon.
Can I just clear P006E?+
It returns as soon as the ECM re-checks the supply voltage; repair the wiring, fuse or ground first.
