TuningBot DTC Database · v4.37.15
8 manufacturer-specific interpretations across 7 manufacturers in the TuningBot DTC database.
ChevroletThe control module detected a fault associated with the HO2S Heater Control Circuit 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 Chevrolet.
ChryslerThe control module detected a fault associated with the HO2S Bank 1 Sensor 2 Average Voltage Level 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 improper operation of the Fuel Restriction Indicator circuit. This is the manufacturer-specific definition used by Ford.
HyundaiThe control module detected improper operation of the Slow Duty Solenoid. This is the manufacturer-specific definition used by Hyundai.
MazdaThe control module detected that the signal in the Heated oxygen sensor (HO2S) 2, bank 1, heater control circuit stayed below the expected operating range. This is the manufacturer-specific definition used by Mazda.
SubaruThe control module judged the Mass air flow (MAF) behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Subaru.
MAF sensor
VAGThe control module judged the Load calculation signal implausible when compared with other operating data. This is the manufacturer-specific definition used by Audi.
The control module judged the Load Calculation Cross Check signal implausible when compared with other operating data. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17549. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).

Diagnostic Trouble Code (8 interpretations). The control module detected a fault associated with the HO2S Heater Control Circuit 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 Chevrolet.
