5% of P0245 cases are fixed by replacing the ECM/PCM
Check These First (Before Buying Parts)
- Visually inspect the wastegate solenoid's electrical connector for corrosion, bent pins, or a loose connection.
- Check the wiring harness leading to the solenoid for any visible damage, cuts, or signs of rodent chewing.
- Ensure any vacuum lines connected to the wastegate actuator (if applicable) are intact and not cracked or disconnected.
How to Diagnose P0245
- 1Visually inspect the wastegate solenoid and its electrical connector for damage, corrosion, or loose connections.
- 2Check the wiring harness leading to the solenoid for any signs of chafing, cuts, or breaks.
- 3Using a multimeter, test for proper voltage supply and ground at the wastegate solenoid connector.
- 4Test the resistance of the wastegate solenoid itself using a multimeter; compare to factory specifications.
- 5If available, use a scan tool with bidirectional control to command the wastegate solenoid on and off and listen for its operation.
P0245 on Popular Vehicles

Frequently Asked Questions
What does P0245 mean?
P0245 indicates that the engine's computer has detected a low voltage condition in the circuit for the turbocharger or supercharger wastegate solenoid 'A'. This means the computer isn't seeing the expected electrical signal from the component that controls boost pressure.
Can I drive with P0245?
Yes, for short trips only. Your vehicle will likely have reduced power and may be in 'limp mode' to protect the engine. Avoid long drives or heavy acceleration until the issue is resolved. Continued driving can lead to further damage.
Will P0245 clear itself?
No, P0245 will not clear itself. This code points to an electrical fault or a component failure that requires diagnosis and repair. The Check Engine Light will remain on until the underlying problem is fixed and the code is cleared, either manually or after several drive cycles once the repair is confirmed.
How do I fix P0245 myself?
Start by visually inspecting the wastegate solenoid and its wiring for obvious damage. If the wiring looks good, you'll need a multimeter to test the voltage at the solenoid connector and the resistance of the solenoid itself. Most often, replacing the wastegate solenoid resolves the issue.
How much does it cost to fix P0245?
A DIY fix for P0245 typically costs $100-$350 for a new wastegate solenoid. If you take it to a professional shop, expect to pay $200-$700, which includes parts and labor.
P0245 keeps coming back - why?
If P0245 keeps returning, it means the initial repair didn't address the root cause. Common reasons for recurrence include: a faulty replacement part, an intermittent wiring issue that wasn't fully resolved, or a rare problem with the engine computer itself.
Will P0245 fail emissions/smog test?
Yes, P0245 will cause your vehicle to fail an emissions or smog test. Any active Check Engine Light indicates a fault in the emissions control system or related components, which prevents the vehicle from passing inspection.
What's the difference between P0245 and P0246?
P0245 indicates a 'low' voltage condition in the wastegate solenoid 'A' circuit, meaning the computer sees less voltage than expected. P0246 indicates a 'high' voltage condition in the same circuit, meaning the computer sees more voltage than expected. Both point to an electrical issue with the solenoid or its wiring, but in opposite directions.
P0245 on Ford F-150 EcoBoost?
On Ford F-150 EcoBoost models, P0245 often points directly to a failing turbocharger wastegate solenoid or its associated vacuum lines. These solenoids can degrade over time, leading to incorrect boost control and triggering the code.
Questions to Ask Your Mechanic
Did you test the voltage and resistance of the wastegate solenoid?
Good answer: Yes, I confirmed the voltage supply is correct, but the solenoid's internal resistance is out of specification, indicating it's faulty.
What did you find when inspecting the wiring harness to the solenoid?
Good answer: I found a section of the wiring harness was chafed and shorting out, causing the low voltage reading. I've repaired the wiring.

Cost of Waiting
Ignoring P0245 can lead to severe engine damage. A malfunctioning wastegate can cause the turbocharger to overboost, potentially damaging the turbo itself, the engine's pistons, or other internal components. A $200 solenoid fix now prevents a $2,000-$5,000 turbo replacement or even a full engine rebuild.
While You're In There...
If your wastegate is vacuum-actuated, these lines are often brittle and can crack, causing boost control issues. They are easily accessible when working on the solenoid.
While not directly related to P0245, if you're diagnosing turbo issues, checking or cleaning the boost sensor can prevent future codes and ensure accurate boost readings.
Tools You'll Need
- OBD-II Scan Tool
- Multimeter
- Socket Set
- Wrench Set
- Screwdrivers
- Wire Strippers/Crimpers (if wiring repair is needed)
P0245 is a common turbocharger control code. Most repairs involve replacing a relatively inexpensive solenoid, and your engine's power will be fully restored afterward.

Your Next Steps
Step 1: Perform a thorough visual inspection of the wastegate solenoid, its electrical connector, and the wiring harness for any obvious damage. Check for loose connections or corrosion.
Step 2: If the visual inspection doesn't reveal the issue, use a multimeter to test the voltage at the solenoid connector and the resistance of the solenoid itself. Compare your readings to your vehicle's service manual specifications.
Step 3: If the solenoid tests faulty or the wiring is damaged, replace the wastegate solenoid or repair the wiring. After repair, clear the code with an OBD-II scan tool and test drive the vehicle.
