Supercharger Disconnect Clutch Circuit Range/Performance
The supercharger clutch control current does not match the commanded value within tolerance. Either coil resistance has drifted or the driver feedback is implausible.
Affected components
- Supercharger clutch
- Clutch solenoid
- Wiring harness
Common causes
- Medium likelihood: Coil resistance increased due to thermal damage
- Medium likelihood: High-resistance contact in the clutch connector
- Low likelihood: Sensor element aged beyond calibration window
Possible symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
Diagnostic notes
- The malfunction indicator lamp may illuminate
