What P0245 means
The wastegate lets exhaust bypass the turbine to limit boost; actuator A is either a pulse-width-modulated solenoid on a pneumatic wastegate can or an electric actuator with a position sensor. P0245 means the control circuit of actuator A reads low – typically the ground-switched control wire shorted to ground, so the valve would be permanently energised. GM checks with the driver off for less than 0.5 Ω to ground, 10 of 20 samples, warning light in the first trip; Ford's driver chip reports it after 2–5 s, and on pneumatic wastegates Ford also includes the open circuit here. A shorted supply shared with the bypass valve can set it together with P0033/P0034. Boost control is then switched off and only the spring-set base boost remains – less power, but no risk of overboost.
P0245 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0245
- Check engine light on
- Clearly less power, boost only at base level
- Sluggish acceleration, turbo lag
- Reduced engine power message possible
Common causes of P0245
- Most likelyControl wire to the wastegate valve chafed through to ground
- PossibleSolenoid shorted internally
- PossibleShared supply shorted (e.g. by the bypass valve)
- Less likelyDriver stage in the engine module faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0245 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 2 | Area: fuel and air metering (injector circuit). |
| 45 | The exact fault in that area. |
What to do next
- Note P0245 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0245
What does P0245 mean?
P0245 means "Turbocharger/Supercharger Wastegate Actuator A Low". The wastegate lets exhaust bypass the turbine to limit boost; actuator A is either a pulse-width-modulated solenoid on a pneumatic wastegate can or an electric actuator with a position sensor. It is a generic code, so it means the same on every make.
Is it safe to drive with P0245?
Drive gently and only to a workshop. With P0245 the car can go into limp mode (reduced power) to protect itself.
Will P0245 fail an emissions test?
Yes, it can. P0245 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0245 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0245 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
