TuningBot DTC Database · v4.37.15
10 manufacturer-specific interpretations across 6 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.
KiaThe control module detected a fault associated with the Heated oxygen sensor (HO2S) - front, bank 1 - control limit 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.
NissanThe control module detected a fault associated with the Heated oxygen sensor (HO2S) 2, bank 2 - minimum voltage 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.
PSAThe control module detected the fault condition "Measured rail pressure higher than the maximum pressure" for the High pressure fuel regulation. Documented for the Bosch EDC16C34 injection ECU (DV6TED4 1.6 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
The control module detected that the Fuel circuit was above its expected limit. Documented for the Bosch MED 17.4.x engine ECU (EP6 THP family) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
The control module detected the fault condition "Maximum rail pressure exceeded" for the Fuel circuit. Documented for the Continental SID 807 injection ECU (DV6C 1.6 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
The control module detected the fault condition "Maximum rail pressure exceeded" for the Fuel system. 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.
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 a fault associated with the Long term fuel trim 2, Bank 1 - above rich limit circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Audi.
The control module detected a fault associated with the Long term fuel trim above rich limit circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Volkswagen.
Powertrain: engine, transmission and driveline systems.
Manufacturer-defined range: the meaning can differ between brands.
Specific fault index within the subsystem.
Diagnostic Trouble Code (10 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.
P1166 is a manufacturer-specific code. In this database it is documented for: Chevrolet, Kia, Nissan, PSA, Suzuki, 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.
