TuningBot DTC Database · v4.37.15
7 manufacturer-specific interpretations across 7 manufacturers in the TuningBot DTC database.
Alfa RomeoThe control module detected a fault associated with the Heated oxygen 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 Alfa Romeo.
ChevroletThe control module detected improper operation of the Injector 1 circuit. This is the manufacturer-specific definition used by Chevrolet.
FordThe control module detected a fault associated with the Throttle Position Sensor 'B' Out of Self - Test 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 Ford.
JaguarThe control module registered the fault condition described as "Electronic Throttle Control Position Error". This is the manufacturer-specific definition used by Jaguar.
MazdaThe control module detected a fault associated with the Throttle Position Sensor 'B' Out of Self - Test 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 Mazda.
NissanThe control module detected that the Throttle position (TP) sensor 2 voltage stayed above the expected range. This is the manufacturer-specific definition used by Nissan.
VolvoThe control module judged the Throttle position (TP) sensor 8 behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Volvo.
Powertrain: engine, transmission and driveline systems.
Manufacturer-defined range: the meaning can differ between brands.
Specific fault index within the subsystem.
Diagnostic Trouble Code (7 interpretations). The control module detected a fault associated with the Heated oxygen 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 Alfa Romeo.
P1224 is a manufacturer-specific code. In this database it is documented for: Alfa Romeo, Chevrolet, Ford, Jaguar, Mazda, Nissan, Volvo. 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.
