P0335 on Saab
Crankshaft Position Sensor A Circuit Malfunction
P0335 on Saab vehicles indicates crankshaft position sensor a circuit malfunction. Au7o has documented this code across 1 Saab model — most commonly on 9-5. This code means the engine computer has lost or detected a faulty signal from the crankshaft position sensor (sensor A), which tells the computer exactly how fast and in what position the crankshaft is rotating. That signal is essential for timing the spark and fuel injection, so a problem here can cause hard starting, stalling, or a no-start condition. The computer sets this code when the crank sensor signal is missing, erratic, or out of its expected pattern. Causes range from a failed sensor or damaged wiring to a problem with the reluctor (tone) ring the sensor reads. Typical repair costs on Saab range from $100 to $350, depending on the specific model and root cause.
Common Causes of P0335
- •Failed crankshaft position sensor
- •Damaged, corroded, or loose sensor wiring/connector
- •Metal debris or oil contamination on the sensor tip
- •Damaged or misaligned reluctor (tone) ring
- •Excessive air gap between sensor and tone ring
- •Wiring shorted or open in the sensor circuit
- •Faulty PCM/ECM (rare)

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 P0335 mean on Saab?▼
P0335 stands for "Crankshaft Position Sensor A Circuit Malfunction." This code means the engine computer has lost or detected a faulty signal from the crankshaft position sensor (sensor A), which tells the computer exactly how fast and in what position the crankshaft is rotating.
