P1339 Code failures by brands

P1339 AUDI, VOLKSWAGEN: CRANKSHAFT POSITION/ENGINE SPEED SENSOR CROSS CONNECTED

Description of DTC code P1339

Modern automotive wiring harnesses are complex. They consist of wires and connectors. Most of them meet a standard for use, although certain connectors are proprietary to some manufacturers. However, the design of the wires is to minimize the overall length of wiring used, as well as to make installation easier.

Different connector designs are used for each connection. Despite the best efforts of harness manufacturers, sometimes the same connectors are used in more than one sub-harness. This case occurs with the connectors of some CKP (Crankshaft Position Sensor) and Engine Speed Sensors of VAG group vehicles. The reason is that both harnesses are usually routed along the same place of the engine compartments. For this reason, it is easier to interconnect two different systems during or after certain routine repairs or services.

The P1339 OBDII fault code is set on VW and Audi vehicles when the PCM (Powertrain Control Module) detects the connectors for the CKP Sensor and Engine Speed Sensor are connected on incorrect wiring harnesses. Specifically, the CKP Sensor is connected to the Engine Speed Sensor harness and vice versa.
