TuningBot DTC Database · v4.37.14
11 manufacturer-specific interpretations across 10 manufacturers in the TuningBot DTC database.
ChevroletThe control module detected a fault associated with the Barometric pressure (BARO) sensor performance range circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chevrolet.
ChryslerThe control module judged the Barometric Pressure behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Chrysler.
DodgeThe control module judged the Diesel Particulate Filter System behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Dodge.
FordThe control module detected improper operation of the EVAP Control System Canister Vent Solenoid circuit. This is the manufacturer-specific definition used by Ford.
JeepThe control module judged the Diesel particulate filter (DPF) behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Jeep.
Land RoverThe control module detected that the signal in the Evaporative emission (EVAP) pressure pump circuit stayed above the expected operating range. This is the manufacturer-specific definition used by Land Rover.
LexusThe control module detected improper operation of the Fuel tank pressure sensor, range/performance problem circuit. This is the manufacturer-specific definition used by Lexus.
SuzukiThe control module judged the Barometric pressure (BARO) behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Suzuki.
ECM
ToyotaThe control module judged the Fuel Tank Pressure behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Toyota.
VAGThe control module detected a short circuit to ground 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 ground 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 (11 interpretations). The control module detected a fault associated with the Barometric pressure (BARO) sensor performance range circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chevrolet.
P1451 is a manufacturer-specific code. In this database it is documented for: Chevrolet, Chrysler, Dodge, Ford, Jeep, Land Rover, Lexus, Suzuki, 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.
