P1454 Code défaut de diagnostic (7 interprétations)

The control module judged the Fuel tank pressure signal implausible: it stayed inside electrical limits but did not match the value expected for the current operating conditions. This is the manufacturer-specific definition used by Honda.

The control module detected a fault associated with the Evaporative Emission Control System Vacuum Test 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 that the Diesel particulate filter (DPF) pressure differential sensor - flow value was above the expected limit. This is the manufacturer-specific definition used by Jeep.

The control module detected a fault associated with the Secondary Air Injection Pump With Series Resistor Control Circuit Electrical circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by MINI.

The control module detected a short circuit to battery voltage in the EGR electrovalve control circuit. Documented for the Magneti Marelli MM6KP engine ECU (EW7A/EW10A) 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 Exhaust gas recirculation temperature (EGRT) sensor 1/Bank 1 circuit. This is the manufacturer-specific definition used by Audi.

The control module detected a short circuit to ground in the Exhaust gas recirculation temperature (EGRT) circuit. This is the manufacturer-specific definition used by Volkswagen.
