TuningBot DTC Database · v4.37.15
5 manufacturer-specific interpretations across 1 manufacturer in the TuningBot DTC database.
PSAPSAThe control module detected that the expected Fault was absent. Documented for the Bosch ESP 8.1 stability control ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models.
The stored code identifies a fault of the Engine torque information fault. 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. PSA documentation does not characterise the failure mode further.
The stored code identifies a fault of the Engine torque fault. Documented for the Bosch MEV17.4 engine ECU (EP6 1.6 VTi) on Peugeot applications; the same PSA control units are also fitted to Citroën models. PSA documentation does not characterise the failure mode further.
The control module detected the fault condition "Error in length or prohibited value on the gearbox datastream" for the Intersystems CAN. 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 an internal control-unit fault (Length or prohibited value error of the frame BV). 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.
Network: communication between control units.
Manufacturer-defined range: the meaning can differ between brands.
Specific fault index within the subsystem.
Diagnostic Trouble Code (5 interpretations). The control module detected that the expected Fault was absent. Documented for the Bosch ESP 8.1 stability control ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models.
U1309 is a manufacturer-specific code. In this database it is documented for: PSA. The same number can mean something different on other brands.
Not guaranteed. Powertrain (P) codes can be reliably disabled in the ECU calibration, but body, chassis and network codes depend on the specific control unit and how the fault is implemented - some can be handled, some cannot. Ask for a quote and our engineers will check your file and tell you, free of charge, whether U1309 is removable in your case.
