TuningBot DTC Database · v4.37.15
13 manufacturer-specific interpretations across 12 manufacturers in the TuningBot DTC database.
ChevroletThe control module detected that the Heated oxygen sensor (HO2S) 2, bank 1 voltage stayed below the expected range. This is the manufacturer-specific definition used by Chevrolet.
ChryslerThe control module detected a fault associated with the HO2S Bank 1 Sensor 2 Lean Or Low 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 Chrysler.
FordThe control module detected a fault associated with the Lack Of O2 Switches Bank 1 Sensor 2 Lean 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.
Land RoverThe control module detected a fault associated with the Heated oxygen sensor (HO2S) 2 - cylinders 1, 2, 3 - mixture lean 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.
Mercedes-BenzThe control module detected an electrical fault in the Heated oxygen sensor (HO2S) 2 - signal/ circuit. This is the manufacturer-specific definition used by Mercedes-Benz.
MINIThe control module detected a fault associated with the O2 Sensor Heater Circuit Signal Intermittent 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 MINI.
NissanThe control module detected improper operation of the Intake manifold air control actuator position 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.
SubaruThe control module judged the Heated oxygen sensor (HO2S) 1 behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Subaru.
SuzukiThe control module detected that the signal in the HO2S circuit stayed below the expected operating range. This is the manufacturer-specific definition used by Suzuki.
VAGThe control module detected that the air-fuel mixture stayed richer than the target despite full corrective control (Long term fuel trim, idling, Bank 1 - 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 (Fuel Trim: Bank 1 (Add): System). This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17545. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
Malfunction Indicator Light (MIL) active
VolvoThe control module detected a fault associated with the Heated oxygen sensor (HO2S) 1, bank 2 - lean circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Volvo.
Powertrain: engine, transmission and driveline systems.
Manufacturer-defined range: the meaning can differ between brands.
Specific fault index within the subsystem.
Diagnostic Trouble Code (13 interpretations). The control module detected that the Heated oxygen sensor (HO2S) 2, bank 1 voltage stayed below the expected range. This is the manufacturer-specific definition used by Chevrolet.
P1137 is a manufacturer-specific code. In this database it is documented for: Chevrolet, Chrysler, Ford, Land Rover, Mercedes-Benz, MINI, Nissan, Porsche, Subaru, Suzuki, VAG, Volvo. 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.
