TuningBot DTC Database · v4.37.15
4 manufacturer-specific interpretations across 2 manufacturers in the TuningBot DTC database.
ChevroletThe control module detected a fault associated with the Fuel pump speed circuit - high duty cycle circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chevrolet.
PSAThe control module detected that the Injector 1 is jammed or locked. Documented for the Bosch MED 17.4.x engine ECU (EP6 THP family) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
The control module detected that the No. 1 cylinder is jammed or locked. 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 "Fuel injector wear" for the Correction of injector flow rate cylinder 1. 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.
