P0336 on Saab
Crankshaft Position Sensor 'A' Circuit Range/Performance
P0336 on Saab vehicles indicates crankshaft position sensor 'a' circuit range/performance. Au7o has documented this code across 1 Saab model — most commonly on 9-5. 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. Typical repair costs on Saab range from $100 to $350, depending on the specific model and root cause.
Common Causes of P0336
- •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)
P0336 on Saab by Model
Saab 9-5(1 issue)
- Crankshaft Position Sensor (CPS) Hot No-Start1999-2009
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.

What does P0336 mean on Saab?▼
P0336 stands for "Crankshaft Position Sensor 'A' Circuit Range/Performance."
