TuningBot DTC Database · v4.37.14
8 manufacturer-specific interpretations across 7 manufacturers in the TuningBot DTC database.
JeepThe control module judged the Diesel particulate filter (DPF) pressure differential sensor hose behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Jeep.
Land RoverThe control module detected a fault associated with the Evaporative emission (EVAP) pressure pump - low current circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Land Rover.
LexusThe control module detected improper operation of the Fuel tank pressure sensor, low input circuit. This is the manufacturer-specific definition used by Lexus.
MazdaThe control module detected a fault associated with the Evaporative emission (EVAP) system - fuel tank vacuum test failed circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Mazda.
MINIThe control module detected a condition consistent with a leak affecting the Diagnostic Module Tank. This is the manufacturer-specific definition used by MINI.
ToyotaThe control module detected that the Fuel Tank Pressure signal stayed below the expected range. This is the manufacturer-specific definition used by Toyota.
VAGThe control module detected an interruption (open circuit) in the Secondary air injection (AIR) system circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Audi.
The control module detected an interruption (open circuit) in the Secondary air injection (AIR) system circuit, so the expected electrical continuity was not present. 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 judged the Diesel particulate filter (DPF) pressure differential sensor hose behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Jeep.
P1452 is a manufacturer-specific code. In this database it is documented for: Jeep, Land Rover, Lexus, Mazda, 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.
