What Does P1245 Mean?
DTC P1245 indicates the wastegate control solenoid valve has entered a fail-safe operating mode. The PCM has detected a persistent malfunction in the wastegate control system and has defaulted to a protective strategy that limits boost pressure to prevent engine damage. This typically means the system has locked boost at a safe, reduced level.
Safety Warning
The fail-safe mode significantly reduces engine power to protect the engine. While this is a protective measure, the sudden and significant loss of power can be dangerous in traffic. The underlying cause should be repaired promptly.
Common Causes
30%
Persistent wastegate solenoid electrical failure triggering fail-safe
25%
Wastegate actuator mechanically stuck requiring fail-safe intervention
20%
Boost pressure sensor providing implausible readings to the PCM
15%
Multiple failed attempts by PCM to control boost resulting in fail-safe mode
10%
Turbocharger bearing failure causing abnormal boost behavior
Diagnostic Steps
1
Check for companion DTCs — P1245 is typically a secondary code triggered after other boost control faults (P1233, P1244) have been detected. Diagnose those codes first.
2
Clear all codes and perform a road test to determine if the fail-safe re-engages immediately or after a specific operating condition.
3
Monitor boost pressure, wastegate solenoid duty cycle, and turbo speed (if available) with a scan tool during the test drive.
4
Physically inspect the wastegate actuator, linkage, and solenoid for mechanical and electrical integrity.
5
If the turbocharger shaft play exceeds specification (check with a dial indicator), the turbo may need rebuilding or replacement.
6
After repairing the root cause, clear codes and verify that the fail-safe does not re-engage during a complete drive cycle.

The most common cause of P1245 (Wastegate control solenoid valve malfunction (fail-safe)) is: Persistent wastegate solenoid electrical failure triggering fail-safe
Typical repair costs for P1245 range from $200 to $1,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The fail-safe mode significantly reduces engine power to protect the engine. While this is a protective measure, the sudden and significant loss of power can be dangerous in traffic. The underlying cause should be repaired promptly.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1245 to identify the root cause.
