TuningBot DTC Database · v4.37.15
10 manufacturer-specific interpretations across 9 manufacturers in the TuningBot DTC database.
JaguarThe control module detected that the signal in the Pedal Position Sensor A circuit stayed above the expected operating range. This is the manufacturer-specific definition used by Jaguar.
KiaThe control module detected a fault associated with the Long Term Fuel Trim Adaptive Air System Low circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Kia.
Land RoverThe control module detected that the Throttle position (TP) voltage stayed below the expected range. This is the manufacturer-specific definition used by Land Rover.
LexusThe control module detected that the signal in the Coolant Flow Control Valve Position circuit stayed above the expected operating range. This is the manufacturer-specific definition used by Lexus.
MazdaThe control module determined that the Throttle position (TP) did not change state as commanded and appears stuck. This is the manufacturer-specific definition used by Mazda.
MINIThe control module detected that the Pedal Position 1 signal stayed above the expected range. This is the manufacturer-specific definition used by MINI.
PorscheThe control module detected a fault associated with the Oxygen Sensor Heating circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Porsche.
ToyotaThe control module detected that the signal in the Coolant Flow Control Valve Position circuit stayed above the expected operating range. This is the manufacturer-specific definition used by Toyota.
VAGThe control module detected that the air-fuel mixture stayed richer than the target despite full corrective control (Long Term Fuel Trim Adjustment Bank 1 System). This is the manufacturer-specific definition used by Audi.
The control module detected that the air-fuel mixture stayed richer than the target despite full corrective control (Long Term Fuel Trim Adjustment Bank 1 System). 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 (10 interpretations). The control module detected that the signal in the Pedal Position Sensor A circuit stayed above the expected operating range. This is the manufacturer-specific definition used by Jaguar.
P1123 is a manufacturer-specific code. In this database it is documented for: Jaguar, Kia, Land Rover, Lexus, Mazda, MINI, Porsche, 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. 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.
