Heated oxygen sensor (HO2S) 1, bank 2 mixture variation between cylinders
Chevrolet · emissions
Data confidence62%
The control module detected a fault associated with the Heated oxygen sensor (HO2S) 1, bank 2 mixture variation between cylinders 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.
System Too Rich Banks 1 And 2 (Suspect HO2S)
Jaguar · emissions
Data confidence62%
The control module detected that the air-fuel mixture stayed richer than the target despite full corrective control (System). This is the manufacturer-specific definition used by Jaguar.

The control module detected a fault associated with the Heated oxygen sensor (HO2S) 1, bank 2 mixture variation between cylinders 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.
Is P1175 generic or manufacturer-specific?
P1175 is a manufacturer-specific code. In this database it is documented for: Chevrolet, Ford, Jaguar, Kia, Land Rover, MINI, Suzuki, VAG, Volvo. The same number can mean something different on other brands.
Can TuningBot remove P1175 at file level?
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.
