P1339 Diagnostic Trouble Code (5 interpretations)
5 manufacturer-specific interpretations across 2 manufacturers in the TuningBot DTC database.
PSA
3 interpretationsThe stored code identifies a fault of the 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 stored code identifies a fault of the High combustion misfiring on cylinder 3. Documented for the Magneti Marelli MM6KP engine ECU (EW7A/EW10A) on Peugeot applications; the same PSA control units are also fitted to Citroën models. PSA documentation does not characterise the failure mode further.
VAG
2 interpretationsThe control module detected a fault associated with the Crankshaft position (CKP) sensor/ engine speed (RPM) sensor - interchanged circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Audi.
Possible causes
Multi - plugs incorrectly connected
