TuningBot DTC Database · v4.37.14
10 manufacturer-specific interpretations across 9 manufacturers in the TuningBot DTC database.
ChryslerThe control module detected a fault associated with the Closed loop fuel control not achieved - bank 2 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 2 signal error". This is the manufacturer-specific definition used by Dodge.
HondaThe control module detected that the MAP sensor value was higher than expected for the current conditions. This is the manufacturer-specific definition used by Honda.
HyundaiThe control module detected improper operation of the 2nd Lock Solenoid. This is the manufacturer-specific definition used by Hyundai.
JeepThe control module detected a fault associated with the Closed loop fuel control not achieved - bank 2 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.
Land RoverThe control module detected a fault associated with the Heated oxygen sensors (HO2S) 1 - sensors 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
MitsubishiThe control module detected a fault associated with the Closed Loop Fueling Not Achieved Bank 2 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.
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 richer than the target despite full corrective control (Long term fuel trim, entire speed/load range, Bank 2 - system). This is the manufacturer-specific definition used by Audi.
The control module detected that the air-fuel mixture stayed richer than the target despite full corrective control (Long term fuel trim, system). This is the manufacturer-specific definition used by Volkswagen.
Powertrain: engine, transmission and driveline systems.

Specific fault index within the subsystem.
Diagnostic Trouble Code (10 interpretations). The control module detected a fault associated with the Closed loop fuel control not achieved - bank 2 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.
P1129 is a manufacturer-specific code. In this database it is documented for: Chrysler, Dodge, Honda, Hyundai, Jeep, Land Rover, Mitsubishi, 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 and, where the ECU needs it, corrects the checksum too. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
