What Does Code P1339 Mean?
OBD II fault code P1339 is a manufacturer-specific code that is defined on VAG group (VW, Audi, etc.) vehicles as “Crankshaft Position/Engine Speed Sensor Cross Connected”, and is set when the PCM (Powertrain Control Module) detects that the connectors for the Crankshaft Position Sensor and the Engine Speed Sensor are connected to the wrong harnesses. More precisely though, that the Crankshaft Position Sensor is connected to the harness of the Engine speed Sensor, and vice versa.
Modern automotive wiring harnesses are hugely complex and can consist of several miles of wire, and one hundred or more connectors, that are, for the most part, standardized and used on all vehicles. However, some connectors are proprietary to some vehicle manufacturers.
Nonetheless, wiring harnesses are designed both to minimize the total length of wiring used, as well as to make harnesses easy to install during vehicle assembly. To make this process easier for vehicle assemblers, and to eliminate the possibility that one or more sub-harnesses could be cross-connected, wiring harnesses are designed so that the connector on one sub-harness can only be connected to the correct connector on the rest of the harness.
This is accomplished by using different connector designs at each connection, but despite the best intentions of harness designers, there are instances where the same connectors are used on more than one sub-harness. One such instance is the connectors on some Crankshaft Position Sensors and Engine Speed Sensors on some VAG-group vehicles since these two harnesses are often routed along the same path in engine compartments. Because of this, it is sometimes easy to cross-connect the two different systems during or after routine repairs/servicing, since there is no difference in how the connectors on these systems fit together- even though one connector pair is typically black, and the other pair is typically gray.
If this happens, the PCM will detect the cross-connection, and set code P1339 as a result.
Where is the P1339 sensor located?
This image shows the relative positions of the Crankshaft Position Sensor and Engine Speed Sensor on an Audi engine. Since it is easy to get the connections wrong on this pair of sensors, it is recommended that reliable service information be consulted to avoid cross-connecting the two sensors and their respective wiring.
What are the common causes of code P1339?
The only cause of this code on VAG-group vehicles is a failure to pay proper attention to the correct installation and/or connection of the two sensors.
What are the symptoms of code P1339?
Typical symptoms could include one or more of the following-
- Stored trouble code and illuminated MIL (CHECK ENGINE) light
- In some cases, multiple additional codes may be present along with P1339
- Engine will crank normally, but will typically not start
