TuningBot DTC Database · v4.37.15
8 manufacturer-specific interpretations across 7 manufacturers in the TuningBot DTC database.
KiaThe control module detected a fault associated with the Electronic throttle system (ETS) - supply voltage 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 a fault associated with the Fuel trim (FT) lean mixture 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 judged the Direct injector fuel performance behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Lexus.
Mercedes-BenzThe control module judged the Engine oil sensor, level signal implausible when compared with other operating data. This is the manufacturer-specific definition used by Mercedes-Benz.
MINIThe control module detected a fault associated with the O2 Sensor Signal Circuit Slow Switching From Rich to Lean Bank 1 Sensor 1 circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by MINI.
VAGThe control module detected an interruption (open circuit) in the Heated oxygen sensor (HO2S) 1, Bank 1, pump current 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 Heated oxygen sensor (HO2S) pump current circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Volkswagen.
VolvoThe control module detected that the air-fuel mixture stayed richer than the target despite full corrective control (System). 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 (8 interpretations). The control module detected a fault associated with the Electronic throttle system (ETS) - supply voltage 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.
P1178 is a manufacturer-specific code. In this database it is documented for: Kia, Land Rover, Lexus, Mercedes-Benz, MINI, VAG, 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.
