TuningBot DTC Database · v4.37.15
10 manufacturer-specific interpretations across 9 manufacturers in the TuningBot DTC database.
BMWThe control module detected a communication fault involving Secondary Pressure Solenoid on the vehicle network. This is the manufacturer-specific definition used by BMW.
DodgeThe control module detected that the signal in the Transmission Throttle Valve Position circuit stayed below the expected operating range. This is the manufacturer-specific definition used by Dodge.
FordThe control module detected a fault associated with the Electronic Pressure Control Solenoid Failed Low Conditions circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Ford.
HyundaiThe control module detected an open circuit or short circuit condition in the Serial Communication Link circuit. This is the manufacturer-specific definition used by Hyundai.
Land RoverThe control module detected a fault associated with the Transmission fluid pressure (TFP) solenoid - low pressure circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Land Rover.
MazdaThe control module detected a fault associated with the AT - electronic pressure control solenoid system circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Mazda.
PorscheThe control module detected a fault associated with the Version coding circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Porsche.
PSAThe control module detected that the Gear selection actuator target position not reached fault was not coherent with related operating data. Documented for the Automated manual gearbox electric control ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models.
The stored code identifies a fault of the Gearbox fault - The gear does not remain engaged. Documented for the MCP 6-speed piloted manual gearbox ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models. PSA documentation does not characterise the failure mode further.
VAGThe control module detected that the Transmission Control Unit state or value did not match what was expected. 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 a communication fault involving Secondary Pressure Solenoid on the vehicle network. This is the manufacturer-specific definition used by BMW.
P1749 is a manufacturer-specific code. In this database it is documented for: BMW, Dodge, Ford, Hyundai, Land Rover, Mazda, Porsche, PSA, 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.
