TuningBot DTC Database · v4.37.15
5 manufacturer-specific interpretations across 4 manufacturers in the TuningBot DTC database.
FordThe control module detected an unstable or intermittent signal in the Output Shaft Speed circuit. This is the manufacturer-specific definition used by Ford.
HyundaiThe control module detected an interruption (open circuit) in the Clutch Actuator “B” circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Hyundai.
MazdaThe control module detected a fault associated with the Turbine shaft speed (TSS) sensor - intermittent 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.
VAGThe control module detected an interruption (open circuit) in the Engine coolant blower motor, speed 2 circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Audi.
The control module detected an interruption (open circuit) in the Engine coolant blower motor, speed 2 circuit, so the expected electrical continuity was not present. 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 (5 interpretations). The control module detected an unstable or intermittent signal in the Output Shaft Speed circuit. This is the manufacturer-specific definition used by Ford.
P1900 is a manufacturer-specific code. In this database it is documented for: Ford, Hyundai, Mazda, 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.
