Turbocharger/Supercharger Wastegate Solenoid A Low
What does P0245 mean?
The P0245 code means the vehicle's onboard diagnostic system has detected: Turbocharger/Supercharger Wastegate Solenoid A Low. This is a moderate severity code.
Common Symptoms
- Check Engine Light illuminated
- Overboost condition -- excessive turbo pressure
- Engine enters limp mode
- Reduced power output
- Possible engine knock under boost
Probable Causes (Ranked by Likelihood)
- Short to ground in wastegate solenoid circuit Very High
- Faulty wastegate solenoid coil (shorted internally) High
- Corroded or damaged solenoid connector pins High
- Damaged wiring harness grounding against metal body Moderate
- PCM internal driver circuit fault Low
Step-by-Step Diagnostic Procedure
-
Disconnect the wastegate solenoid and measure coil resistance -- below 15 ohms typically indicates an internal short
-
Check for continuity between the solenoid signal wire and ground -- should be open (no continuity) with solenoid disconnected
-
Inspect wiring harness for bare wires contacting the engine block or frame
-
Test the PCM output by measuring voltage at the solenoid connector with solenoid disconnected -- should pulse between 0V and battery voltage
-
Replace the solenoid if shorted; repair wiring if a ground fault is found in the harness
Frequently Asked Questions
Can I drive with code P0245?
You can drive short distances, but the solenoid may not properly control the wastegate. This can lead to overboost conditions that risk engine damage. Repair promptly.
What does a low solenoid circuit mean?
It means the PCM detects lower than expected voltage or resistance in the wastegate solenoid circuit, usually due to a short to ground in the wiring or an internally shorted solenoid coil.
Can I test the solenoid with a battery?
Yes. Applying 12V directly to the solenoid terminals should produce an audible click and open the valve. If it does not click, the solenoid is faulty and needs replacement.
