TuningBot DTC Database · v4.37.14
9 manufacturer-specific interpretations across 6 manufacturers in the TuningBot DTC database.
ChryslerThe control module detected a fault associated with the Engine coolant blower motor relay circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chrysler.
Mercedes-BenzThe control module's internal test reported the Evaporative emission (EVAP) canister purge valve(s) as faulty. This is the manufacturer-specific definition used by Mercedes-Benz.
MitsubishiThe control module detected a fault associated with the Low Speed Radiator Fan Control Relay Condition circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Mitsubishi.
PSAThe control module detected the fault condition "Regeneration request too frequent" for the Regeneration not achieved. 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 "Detected overloaded" for the Particle filter. 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 "Detected overloaded" for the Particle filter. 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.
SubaruThe control module detected improper operation of the Thermostat. This is the manufacturer-specific definition used by Subaru.
VAGThe control module detected a short circuit to ground in the EVAP Canister Purge Regulator Valve 2 circuit. This is the manufacturer-specific definition used by Audi.
The control module detected a short circuit to ground in the EVAP Canister Purge Regulator Valve 2 circuit. This is the manufacturer-specific definition used by Volkswagen.

Diagnostic Trouble Code (9 interpretations). The control module detected a fault associated with the Engine coolant blower motor relay circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chrysler.
P1490 is a manufacturer-specific code. In this database it is documented for: Chrysler, Mercedes-Benz, Mitsubishi, PSA, Subaru, 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.
