P1444 Diagnostic Trouble Code (14 interpretations)

The control module detected that the Purge Flow Sensor signal stayed below the expected range. This is the manufacturer-specific definition used by Ford.

The control module detected improper operation of the High voltage short circuit. This is the manufacturer-specific definition used by Honda.

The control module detected a fault associated with the EVAP Canister Purge Control 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 Jaguar.

The control module detected improper operation of the Secondary air injection (AIR) switching valve, valve stuck open, bank 2 circuit. This is the manufacturer-specific definition used by Lexus.

The control module detected that the Evaporative emission (EVAP) canister purge flow signal stayed below the expected range. This is the manufacturer-specific definition used by Mazda.

The control module's internal test reported the Catalytic converter temperature sensor, bank 2 as faulty. This is the manufacturer-specific definition used by Mercedes-Benz.

The control module detected an interruption (open circuit) in the Diagnostic Module Tank Leakage Pump Control circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by MINI.

The control module detected a short circuit to battery voltage in the Particle filter additive system circuit. 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 battery voltage in the Control of the additive pump by wire circuit. 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 a short circuit to battery voltage in the Wired additive pump circuit. Documented for the Delphi DCM 3.5 injection ECU (DW10C 2.0 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected a short circuit to battery voltage in the Particle filter additive system circuit. 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.

The control module determined that the Secondary Air Injection System Switching Valve did not change state as commanded and appears stuck. This is the manufacturer-specific definition used by Toyota.

The control module judged the Exhaust gas recirculation (EGR) valve position behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Audi.

The control module judged the Exhaust gas recirculation (EGR) valve position behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Volkswagen.
