P1434 Diagnose-Fehlercode (10 Interpretationen)

The control module detected a fault associated with the Cold start idle air control (IAC) system - RPM lower then expected circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by BMW.

The control module detected that the signal in the A/C Refrigerant Temperature circuit stayed above the expected operating range. This is the manufacturer-specific definition used by Ford.

The control module detected a fault associated with the Voltage converter module - high voltage 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.

The control module detected a condition consistent with a leak affecting the Diagnostic Module Tank. This is the manufacturer-specific definition used by MINI.

The control module detected the fault condition "Excessive temperature or open circuit" for the Particle filter additive system. 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 "Pump fault" for the Multiplexed additive pump. 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 "Additive pump fault" for the Multiplexed additive pump. 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 the fault condition "Excessive temperature or open circuit" for the Particle filter additive system. 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 detected a short circuit to battery voltage in the Secondary air injection (AIR) pump relay circuit. This is the manufacturer-specific definition used by Audi.

The control module detected a short circuit to battery voltage in the Secondary Air Pump Relay (J299) circuit. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17842. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
