9 manufacturer-specific interpretations across 8 manufacturers in the TuningBot DTC database.
Chevrolet
1 interpretation
Chrysler
1 interpretationThe control module detected a fault associated with the HO2S Bank 2 Sensor 3 Lean System 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.
Recommended checks
- Perform a full module scan
- Review freeze-frame and occurrence data
- Confirm the exact vehicle, ECU and software context
- Inspect relevant wiring and connectors
- Check applicable OEM service information
Land Rover
1 interpretationThe control module detected improper operation of the Heated oxygen sensor (HO2S), too rich, bank 2 circuit. This is the manufacturer-specific definition used by Land Rover.
Possible causes
- Wiring
- H025
- ECM
Mercedes-Benz
1 interpretationThe control module detected improper operation of the Engine oil level switch. This is the manufacturer-specific definition used by Mercedes-Benz.
Possible causes
- Wiring
- engine oil level switch
- ECM
MINI
1 interpretationThe control module detected a fault associated with the Fuel Trim Additive Per Ignition Bank 1 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 MINI.
Nissan
1 interpretationThe control module detected a fault associated with the Heated oxygen sensor (HO2S) 1, bank 2 - lean shift monitoring circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Nissan.
Possible causes
- Wiring
- HO2S
- fuel system
- injector
- air leak
- ECM
PSA
1 interpretationThe control module detected the fault condition "The engine has not encountered the conditions to reset the injector dead times (Rail pressure low)" for the Injectors control. Documented for the Delphi DCM 3.5 injection ECU (DW10C 2.0 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
VAG
2 interpretationsThe control module detected an interruption (open circuit) in the Fuel temperature circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Audi.
Possible causes
- Wiring open circuit/short to positive
- fuel temperature sensor
The control module detected a short circuit to battery voltage in the Fuel Temp Sensor (G81): Open or circuit. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17571. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
Symptoms
- Fuel consumption higher then normal
- Starting the engine is not as easy as normal
- Emission Levels not met
Possible causes
- Wiring/Connectors from/to Fuel Temp Sensor (G81) faulty
- Fuel Temp Sensor (G81) faulty
Recommended checks
- Check Wiring/Connectors from/to Fuel Temp Sensor (G81)
- Check Fuel Temp Sensor (G81)
