What C057E means

C057E
Brake Booster Temperature Sensor A/B Correlation Generic · engine Data confidence 65%

The control module detected a fault associated with the Brake Booster Temperature Sensor A/B Correlation circuit or function; the stored code identifies the affected component rather than a single failure mode.

Symptoms

  • Possible reduced power or limp mode
  • MIL illuminated
  • Possible abnormal turbocharger noise

Possible causes

  • Turbocharger actuator or position sensor fault
  • Sticking variable geometry mechanism
  • Charge-air or vacuum leak
  • Wiring or connector fault

Recommended checks

  • Compare specified vs actual boost with live data
  • Check actuator movement over the full range
  • Check hoses and vacuum lines
  • Inspect wiring and connectors

Frequently asked questions about C057E

What does C057E mean?

Brake Booster Temperature Sensor A/B Correlation. The control module detected a fault associated with the Brake Booster Temperature Sensor A/B Correlation circuit or function; the stored code identifies the affected component rather than a single failure mode.

Is C057E generic or manufacturer-specific?

C057E is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove C057E at file level?

Not guaranteed. Powertrain (P) codes can be reliably disabled in the ECU calibration, but body, chassis and network codes depend on the specific control unit and how the fault is implemented - some can be handled, some cannot. Ask for a quote and our engineers will check your file and tell you, free of charge, whether C057E is removable in your case.
