TuningBot DTC Database · v4.37.15
12 manufacturer-specific interpretations across 11 manufacturers in the TuningBot DTC database.
ChryslerThe 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.
DodgeThe 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.
HondaThe 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.
JeepThe 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.
KiaThe 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.
Land RoverThe 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.
Wiring transposed
LexusThe control module detected improper operation of the Throttle actuator control (TAC) lock. This is the manufacturer-specific definition used by Lexus.
MitsubishiThe 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.
NissanThe control module detected improper operation of the Throttle valve position motor - short circuit. This is the manufacturer-specific definition used by Nissan.
PorscheThe 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.
VAGThe 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).

Diagnostic Trouble Code (12 interpretations). 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.
P1128 is a manufacturer-specific code. In this database it is documented for: Chrysler, Dodge, Honda, Jeep, Kia, Land Rover, Lexus, Mitsubishi, Nissan, Porsche, 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.
