TuningBot DTC Database · v4.37.15
9 manufacturer-specific interpretations across 7 manufacturers in the TuningBot DTC database.
FordThe control module detected a fault associated with the Throttle Control Unit Unable To Control Desired Throttle Angle 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.
HondaThe control module detected a fault associated with the Motor power inverter module - current signal problem circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Honda.
Mercedes-BenzThe control module's internal test reported the Engine control module (ECM), bank 2, knock control as faulty. This is the manufacturer-specific definition used by Mercedes-Benz.
PSAThe control module detected that the Flowmeter signal was below its expected limit. 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 a short circuit to ground in the Oil pressure sensor supply fault circuit. Documented for the MCP 6-speed piloted manual gearbox ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models.
ToyotaThe control module detected a fault associated with the Acceleration Sensor Learning Value circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Toyota.
VAGThe control module detected a short circuit to ground in the AC/heater air temperature control switch circuit. This is the manufacturer-specific definition used by Audi.
The control module detected a short circuit to ground in the AC/heater air temperature control switch circuit. This is the manufacturer-specific definition used by Volkswagen.
VolvoThe control module judged the Electronic throttle system (ETS) behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Volvo.
Powertrain: engine, transmission and driveline systems.
Manufacturer-defined range: the meaning can differ between brands.
Specific fault index within the subsystem.
Diagnostic Trouble Code (9 interpretations). The control module detected a fault associated with the Throttle Control Unit Unable To Control Desired Throttle Angle 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.
P1589 is a manufacturer-specific code. In this database it is documented for: Ford, Honda, Mercedes-Benz, PSA, Toyota, VAG, Volvo. 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.
