P0245

Turbocharger/Supercharger Wastegate Actuator A Low

Q: Is it safe to drive with P0245?

Yes, at reduced power. The engine protects itself by limiting boost, so it's fine to drive gently to a shop, but avoid hard acceleration until it's fixed.

Q: Can I just clear P0245?

It returns as soon as the ECM re-checks the circuit unless the solenoid or its wiring is repaired.

Turbocharger / boost control Generic OBD-II High

What it means

P0245 means the ECM has detected a low-voltage (short-to-ground or open) fault in the control circuit for the turbo/supercharger wastegate solenoid — the valve that regulates boost. With boost control impaired the engine usually falls back to a safe, reduced-power mode. It's an electrical fault in the boost-control system, not an engine mechanical problem, and only applies to forced-induction engines.

High

Can I keep driving? Drivable but down on power — a wastegate control fault typically puts the engine into reduced-boost limp mode. It won't strand you, but performance is limited until fixed.

Common symptoms

What you'll notice

Check-engine light on
Noticeably reduced power and sluggish acceleration
Possible limp/reduced-boost mode
Higher fuel consumption or emissions

Common causes

Most likely first

Failed wastegate control solenoid (low-side circuit fault)Likely
Short to ground or open in the solenoid control wiringCommon
Corroded or loose connector at the solenoidCommon
Failed engine control module driver (rare)Less often

How to diagnose & fix

Work through it in order

Confirm the code and check the boost-control solenoid's command and feedback on a scan tool.
Inspect the solenoid connector and wiring for a short to ground, open, or corrosion.
Measure the solenoid's resistance against spec.
Replace the wastegate control solenoid if it's out of spec, or repair the circuit. Clear and re-test.
