What does P1306 mean?

P-code P1306 means "Boost Calibration High". It is a manufacturer-specific diagnostic trouble code (DTC) in the powertrain. A calibration or relearn procedure is required for the boost calibration high before normal operation can resume. This warning should be addressed within the next few days to avoid further damage. This code applies to OBD-II compliant electric and hybrid vehicles.

Possible Causes

  • Component replacement without performing the required calibration procedure
  • Battery disconnect or power interruption cleared calibration data
  • Software update changed calibration parameters
  • Mechanical adjustment required after part replacement or repair

Recommended Actions

  1. 1 Avoid aggressive driving and schedule a diagnostic appointment within the next 1–3 days
  2. 2 Scan for all DTCs with an OBD-II scanner — note any related codes stored alongside P1306
  3. 3 Perform the required calibration or relearn procedure using a compatible scan tool
  4. 4 Follow the manufacturer's specific calibration sequence for this component
  5. 5 Clear the DTC, road-test the vehicle, and re-scan to confirm whether the fault returns
  6. 6 If the fault persists after inspection and clearing, consult an EV-certified technician for component replacement
