TuningBot DTC Database · v4.37.14
10 manufacturer-specific interpretations across 6 manufacturers in the TuningBot DTC database.
BMWThe 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.
ECM
FordThe 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.
HondaThe 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.
system is OK
MINIThe control module detected a condition consistent with a leak affecting the Diagnostic Module Tank. This is the manufacturer-specific definition used by MINI.
PSAThe 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.
VAGThe 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).

Diagnostic Trouble Code (10 interpretations). 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.
P1434 is a manufacturer-specific code. In this database it is documented for: BMW, Ford, Honda, MINI, 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 and, where the ECU needs it, corrects the checksum too. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
