TuningBot DTC Database · v4.37.15
13 manufacturer-specific interpretations across 12 manufacturers in the TuningBot DTC database.
BMWThe control module detected that related sensor signals for 'A' Camshaft Position did not agree with each other (correlation/plausibility fault). This is the manufacturer-specific definition used by BMW.
ChevroletThe control module detected that the signal in the HO2S circuit stayed below the expected operating range. This is the manufacturer-specific definition used by Chevrolet.
FordThe control module detected a fault associated with the Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Lean 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 Ford.
HyundaiThe control module detected a fault associated with the Fuel Adjustment Resistor 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.
Land RoverThe control module detected that the air-fuel mixture stayed leaner than the target despite full corrective control (Heated oxygen sensor (HO2S), upstream, bank 1 - mixture). This is the manufacturer-specific definition used by Land Rover.
Mercedes-BenzThe control module detected an electrical fault in the Heated oxygen sensor (HO2S) 1 - signal/ circuit. This is the manufacturer-specific definition used by Mercedes-Benz.
MINIThe control module detected a fault associated with the Oxygen Sensor Behind Catalytic Converter 2 Ageing 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 solenoid. This is the manufacturer-specific definition used by Nissan.
SubaruThe control module detected improper operation of the Heated oxygen sensor (HO2S) 1 - short circuit. This is the manufacturer-specific definition used by Subaru.
SuzukiThe control module detected that the Heated oxygen sensor (HO2S) 1, bank 1 - output voltage stayed above the expected range. This is the manufacturer-specific definition used by Suzuki.
VAGThe control module detected that the Heated oxygen sensor (HO2S) 1, Bank 1 - heater resistance value was above the expected limit. This is the manufacturer-specific definition used by Audi.
The control module detected that the Oxygen/Lambda Sensor Bank 2 Sensor 1: Internal Resistance value was above the expected limit. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17539. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
Malfunction Indicator Light (MIL) ON
VolvoThe control module detected improper operation of the Heated oxygen sensor (HO2S) 1, bank 1. 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 related sensor signals for 'A' Camshaft Position did not agree with each other (correlation/plausibility fault). This is the manufacturer-specific definition used by BMW.
P1131 is a manufacturer-specific code. In this database it is documented for: BMW, Chevrolet, Ford, Hyundai, Land Rover, Mercedes-Benz, MINI, Nissan, 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.
