TuningBot DTC Database · v4.37.15
11 manufacturer-specific interpretations across 10 manufacturers in the TuningBot DTC database.
ChevroletThe control module detected a fault associated with the HO2S Transition Time Ratio Bank 1 Sensor 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 Chevrolet.
DodgeThe control module detected a fault associated with the Vacuum Reservoir Solenoid Circuit Condition circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Dodge.
FordThe control module detected a fault associated with the Water In Fuel Condition circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Ford.
HyundaiThe control module detected a fault associated with the Rationality Check - Throttle Position Sensor (TPS), Mass Air Flow (MAF) Sensor circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Hyundai.
JeepThe control module detected a fault associated with the Vacuum Reservoir Solenoid Circuit Condition 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 Load Calculation Cross Check 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.
MINIThe control module judged the Mass or Volume Air Flow signal implausible: it stayed inside electrical limits but did not match the value expected for the current operating conditions. This is the manufacturer-specific definition used by MINI.
PorscheThe control module detected a fault associated with the Load Signal 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.
SubaruThe control module judged the Heated oxygen sensor (HO2S) 1, bank 2, heater behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Subaru.
VAGThe control module detected that the Heated oxygen sensor (HO2S) 2, Bank 2 - heater resistance value was above the expected limit. This is the manufacturer-specific definition used by Audi.
The control module detected that the Heated oxygen sensor (HO2S) heater resistance value was above the expected limit. This is the manufacturer-specific definition used by Volkswagen.

Diagnostic Trouble Code (11 interpretations). The control module detected a fault associated with the HO2S Transition Time Ratio Bank 1 Sensor 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 Chevrolet.
P1140 is a manufacturer-specific code. In this database it is documented for: Chevrolet, Dodge, Ford, Hyundai, Jeep, Kia, MINI, Porsche, Subaru, 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.
