P1128 Code défaut de diagnostic (12 interprétations)

The control module detected a fault associated with the Closed loop fuel control not achieved - bank 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 Chrysler.

The control module registered the fault condition described as "Heated oxygen sensor (HO2S) 1, bank 1 signal error". This is the manufacturer-specific definition used by Dodge.

The control module detected that the MAP sensor value was lower than expected for the current conditions. This is the manufacturer-specific definition used by Honda.

The control module detected a fault associated with the Closed loop fuel control not achieved - bank 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 Jeep.

The control module detected a fault associated with the Long Term Fuel Trim Multiplicative Air System High 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 Heated oxygen sensor (HO2S), upstream - transposed 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 detected improper operation of the Throttle actuator control (TAC) lock. This is the manufacturer-specific definition used by Lexus.

The control module detected a fault associated with the Closed Loop Fueling Not Achieved Bank 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 Mitsubishi.

The control module detected improper operation of the Throttle valve position motor - short circuit. This is the manufacturer-specific definition used by Nissan.

The control module detected a fault associated with the Oxygen Sensing 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.

The control module detected that the air-fuel mixture stayed leaner than the target despite full corrective control (Long term fuel trim, entire speed/load range, Bank 1 - system). This is the manufacturer-specific definition used by Audi.

The control module detected that the air-fuel mixture stayed leaner than the target despite full corrective control (Fuel Trim; Bank 1 (Mult): System). This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17536. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
