12 manufacturer-specific interpretations across 12 manufacturers in the TuningBot DTC database.

BMW

1 interpretation
P1300
Heated Catalyst Heater Power Supply Open Circuit Bank 2 BMW · emissions Data confidence 62%

The control module detected an interruption (open circuit) in the Heated Catalyst Heater Power Supply circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by BMW.

Dodge

1 interpretation
P1300
Ignition timing adjustment Dodge · engine Data confidence 62%

The control module detected a fault associated with the Ignition timing adjustment circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Dodge.

Possible causes

  • Wiring
  • ignition timing connector short to ground
  • ECM

Ford
