TuningBot DTC Database · v4.37.14
8 manufacturer-specific interpretations across 7 manufacturers in the TuningBot DTC database.
ChryslerThe control module detected improper operation of the Barometric Pressure circuit. This is the manufacturer-specific definition used by Chrysler.
FordFord documents P1450:00 for its 2024-2025 gasoline-engine OBD monitor strategy as "Unable to Bleed Up Fuel Tank Vacuum (excessive vacuum)". This three-byte interpretation is application-specific and identifies the detected monitor condition rather than a confirmed failed component.
Land RoverThe control module detected that related sensor signals for Evaporative emission (EVAP) pressure pump did not agree with each other (correlation/plausibility fault). This is the manufacturer-specific definition used by Land Rover.
LexusThe control module detected improper operation of the Fuel tank pressure circuit. This is the manufacturer-specific definition used by Lexus.
MINIThe control module detected an interruption (open circuit) in the Diagnostic Module Tank Leakage Switching Solenoid circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by MINI.
ToyotaThe control module detected a fault associated with the Fuel Tank Pressure Sensor circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Toyota.
VAGThe control module detected a short circuit to battery voltage in the Secondary air injection (AIR) system circuit. This is the manufacturer-specific definition used by Audi.
The control module detected a short circuit to battery voltage in the Secondary air injection (AIR) system circuit. This is the manufacturer-specific definition used by Volkswagen.
Powertrain: engine, transmission and driveline systems.
Manufacturer-defined range: the meaning can differ between brands.
Specific fault index within the subsystem.
Diagnostic Trouble Code (8 interpretations). The control module detected improper operation of the Barometric Pressure circuit. This is the manufacturer-specific definition used by Chrysler.
P1450 is a manufacturer-specific code. In this database it is documented for: Chrysler, Ford, Land Rover, Lexus, MINI, Toyota, VAG. The same number can mean something different on other brands.
If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry and, where the ECU needs it, corrects the checksum too. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
