P0339 on Saab: Causes, Symptoms and Fix Cost
Quick Answer
Not safe to drive
P0339 on a Saab means the crankshaft position signal reaching the engine computer keeps dropping out and returning. The crankshaft signal times spark and fuel injection, so every dropout can cause a stumble, a stall or a no-restart. Because the fault comes and goes, it often points to a connector, a wire that breaks under heat or vibration, or a marginal sensor.

The Quick Answer above is the generic definition. What follows is the model-specific detail for the Saab models that log P0339.
Saab 9-5
2010-2012
Saab's factory procedure for P0339 on the 1.6 litre turbo petrol sets the code when the crankshaft sensor signal is not continuous while the engine runs. Its checks are a steady 200-300 rpm on the scan tool while cranking, and moving the sensor harness and connectors with the engine running to see whether it stumbles, stalls or changes speed. If the sensor lead is damaged in any way, the procedure replaces the sensor.
What causes P0339 on a Saab?
Beyond the generic causes listed on the main P0339 page, these are the patterns noted for Saab models:
Intermittent connection in the crankshaft sensor harness or connector
: Saab 9-5
Damaged sensor lead or O-ring
: Saab 9-5
How to diagnose P0339 on a Saab with OBD2
Follow these steps to pinpoint the root cause of P0339:
- Read all codes and freeze-frame data, and note the engine temperature and speed when P0339 was stored, because that shows whether heat or vibration is involved
- Check for P0335, P0336 and cam sensor codes, since a crank fault is often logged beside them
- Inspect the sensor connector and wiring for oil, coolant or corrosion, chafed insulation, and check for heat damage near the exhaust
- With the engine idling, gently wiggle the harness and connector while watching engine speed on a scan tool and listening for a stumble. A generic OBD2 reader shows the engine speed reading only, so a very short dropout may need an oscilloscope to catch
- Check that the sensor is firmly mounted and that no metal debris is stuck to its tip
- Test the sensor supply, ground and signal against the manufacturer specification, ideally while the engine is hot
- Inspect the toothed wheel on the crankshaft for damage if the sensor and wiring are good
