P0336 on Saab by model: symptoms, diagnosis and fix
The crankshaft position sensor on the first-generation 9-5 (B235 engine) is a very common failure item. As it degrades it tends to fail when the engine is hot, producing the classic 'hot no-start': the engine cranks but will not fire when warm, then restarts after cooling. It can also cause intermittent stalling while driving, a real safety concern.
Common Symptoms
- Hot no-start (cranks but won't start when warm)
- Intermittent stalling
- Restarts after cooling down
- Check engine light
How to Fix
Replace the crankshaft position sensor with an OEM/Bosch-quality part - cheap unbranded aftermarket sensors are reported to fail again within months. The sensor is relatively inexpensive but located awkwardly near the bell-housing.

Frequently asked questions
What does P0336 mean on a Saab?
P0336 stands for "Crankshaft Position Sensor 'A' Circuit Range/Performance." P0336 means the engine control module detected a crankshaft position sensor signal that is present but outside the expected range or pattern — for example, intermittent dropouts, an erratic waveform, or extra/missing pulses. The crankshaft position sensor tells the computer the exact position and speed of the crankshaft, which is essential for timing fuel injection and ignition. When this signal is unreliable, the engine may stumble, stall, hesitate, or be hard to start. Because it underpins basic engine operation, this code should be addressed promptly. On Saab it is documented across 1 model: 9-5.
What are the most common causes of P0336?
The most common causes of P0336 are: Failing crankshaft position sensor, Damaged or contaminated reluctor/tone ring (debris, missing teeth), Wiring damage, chafing, or corroded connectors, Incorrect air gap or loose sensor mounting, Electrical interference from nearby high-voltage components, Metal shavings on the sensor tip, ECM/PCM fault (less common). The specific cause varies by vehicle.
How much does it cost to fix P0336 on a Saab?
Published repair estimates on Saab range from $100 to $350 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
