P1178 Code défaut de diagnostic (8 interprétations)

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.

The 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.

The control module judged the Direct injector fuel performance behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Lexus.

The 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.

The 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.

The 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.

The 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.
