P0322 on Saab: Causes, Symptoms and Fix Cost
Quick Answer
Not safe to drive
P0322 on a Saab means the engine computer is not receiving any engine speed signal. On most modern cars that signal comes from the crankshaft position sensor, and on older cars it can come from the distributor or an ignition module. With no speed signal the computer cannot time spark or fuel, so the engine usually will not start or will stall.

The Quick Answer above is the generic definition. What follows is the model-specific detail for the Saab models that log P0322.
Saab 900
1994-1998
On the naturally aspirated 900 with Bosch Motronic 2.8.1, Saab's procedure logs P0322 when the engine fails to start because the crankshaft sensor input is missing. With the connector unplugged, the sensor should give about 2-5 V AC while the starter turns and measure 500-600 ohms; the procedure also checks that the toothed ring turns with the crankshaft, that its holes are not clogged and that the sensor gap is about 0.4-1.3 mm.
What causes P0322 on a Saab?
Beyond the generic causes listed on the main P0322 page, these are the patterns noted for Saab models:
Failed crankshaft position sensor
: Saab 900
Wiring fault between the sensor and the control module
: Saab 900
Clogged toothed ring or wrong sensor gap
: Saab 900
How to diagnose P0322 on a Saab with OBD2
Follow these steps to pinpoint the root cause of P0322:
- Read all codes and check whether P0335, P0336, P0339 or cam sensor codes are stored too
- Crank the engine while watching engine speed on a scan tool: a reading of zero while the starter turns means the signal is truly missing
- Inspect the sensor connector and wiring for oil, coolant, corrosion, chafing and broken wires
- Check that the sensor is fitted and tightly mounted and that its tip is clean
- Test the sensor supply, ground and signal against the manufacturer specification
- On older cars with a distributor, inspect the pickup and ignition module
- Inspect the toothed wheel for damage and check the engine control unit for water or coolant if the rest tests good
