TuningBot DTC Database · v4.37.15
11 manufacturer-specific interpretations across 9 manufacturers in the TuningBot DTC database.
BMWThe control module detected an electrical fault in the Battery temperature sensor circuit. This is the manufacturer-specific definition used by BMW.
DodgeThe control module detected a fault associated with the Cabin Heater 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 Dodge.
HondaThe control module detected that the Motor torque signal signal stayed above the expected range. This is the manufacturer-specific definition used by Honda.
Land RoverThe control module detected improper operation of the Fuel pump (FP) circuit. This is the manufacturer-specific definition used by Land Rover.
MazdaThe control module detected improper operation of the Fuel pump circuit. This is the manufacturer-specific definition used by Mazda.
Mercedes-BenzThe control module detected a fault associated with the Engine control module (ECM), bank 1 & 2 - TP signal circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Mercedes-Benz.
PSAThe control module detected the fault condition "ECU internal fault" for the Engine ECU. 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 the fault condition "Failure of the initialisation of the injector bank, or harness fault" for the ECU. 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 "Power stage, injector control" for the Injection electronic control unit. Documented for the Siemens SID 803 injection ECU (DW10BTED4 2.0 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
RenaultThe control module detected a fault associated with the Heater relay control circuit 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 Renault. Renault diagnostic tools (CLIP) report this fault as DF032.
VAGThe control module detected a fault associated with the Check DTC Memory Of Air Condition ECU 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 (11 interpretations). The control module detected an electrical fault in the Battery temperature sensor circuit. This is the manufacturer-specific definition used by BMW.
P1641 is a manufacturer-specific code. In this database it is documented for: BMW, Dodge, Honda, Land Rover, Mazda, Mercedes-Benz, PSA, Renault, 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.
