P1300 Diagnostic Trouble Code (12 interpretations)
12 manufacturer-specific interpretations across 12 manufacturers in the TuningBot DTC database.
BMW
1 interpretation
Dodge
1 interpretationThe 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
1 interpretationThe control module detected improper operation of the Boost Pressure. This is the manufacturer-specific definition used by Ford.
Honda
1 interpretationThe control module detected a fault associated with the Random misfire 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
- lgnition/fuei/EGR system
- MAP sensor
- lAC valve
Land Rover
1 interpretationThe control module detected crankshaft speed fluctuations consistent with combustion misfire (Random/multiple cylinder(s)). This is the manufacturer-specific definition used by Land Rover.
Possible causes
- Engine mechanical fault
- wiring
- ignition/fuel system
- injector
- ECT/MAF sensor
- ECM
Mercedes-Benz
1 interpretationThe control module detected improper operation of the Crankshaft position (CKP) sensor(s). This is the manufacturer-specific definition used by Mercedes-Benz.
Possible causes
- Wiring
- flywheel ring gear damaged
- CKP sensor(s)
MINI
1 interpretationThe control module detected a fault associated with the Camshaft Sensor Inlet Gap Loss circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by MINI.
Mitsubishi
1 interpretationThe control module detected improper operation of the Ignition timing adjustment circuit. This is the manufacturer-specific definition used by Mitsubishi.
Possible causes
- Wiring short to ground
- ECM
Opel
1 interpretationThe control module detected a fault associated with the Fuel tank - empty circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Opel.
Subaru
1 interpretationThe control module detected improper operation of the Crankshaft Position Sensor 2 circuit. This is the manufacturer-specific definition used by Subaru.
VAG
1 interpretationThe control module detected crankshaft speed fluctuations consistent with combustion misfire (Random/multiple cylinder(s)). This is the manufacturer-specific definition used by Audi.
Possible causes
- Fuel level low
- fuel gauge tank sensor

Frequently asked questions about P1300
What does P1300 mean?
Diagnostic Trouble Code (12 interpretations). 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.
Is P1300 generic or manufacturer-specific?
P1300 is a manufacturer-specific code. In this database it is documented for: BMW, Dodge, Ford, Honda, Land Rover, Mercedes-Benz, MINI, Mitsubishi, Opel, Subaru, VAG, Volvo. The same number can mean something different on other brands.
Can TuningBot remove P1300 at file level?
If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry. Checksum correction is not included: it is a separate, optional service. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
