Honda

1 interpretation
P1446
Hybrid battery pack - individual voltage input deviation Honda · hybrid Data confidence 62%

The control module detected a fault associated with the Hybrid battery pack - individual voltage input deviation circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Honda.

Possible causes

  • Wiring
  • hybrid battery pack
  • motor control module (MCM) programming
  • MCM

Kia

P1446
Evaporative emission (EVAP) leak detection module solenoid - circuit malfunction Kia · emissions Data confidence 62%

The control module detected improper operation of the Evaporative emission (EVAP) leak detection module solenoid circuit. This is the manufacturer-specific definition used by Kia.

Possible causes

  • Wiring
  • EVAP leak detection module solenoid

MINI

1 interpretation
P1446
Diagnostic Module Tank Leakage Pump Control Circuit Signal High MINI · engine Data confidence 62%

The control module detected a condition consistent with a leak affecting the Diagnostic Module Tank. This is the manufacturer-specific definition used by MINI.
