P0335 on Saturn
Crankshaft Position Sensor A Circuit Malfunction
P0335 on Saturn vehicles indicates crankshaft position sensor a circuit malfunction. Au7o has documented this code across 2 Saturn models — most commonly on Astra, Vue. 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 Saturn range from $600 to $4,000, 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)
P0335 on Saturn by Model
Saturn Astra(1 issue)
- Astra 1.8L Z18XER Water Pump / Timing Chain Wear2008-2009
2008-2009 Saturn Astra is the Belgian-built Opel Astra H rebadged. The 1.8L Z18XER engine's water pump is driven from the timing chain — pump failure can jam the chain and bend valves. Common at 80,000-130,000 miles. Parts have become scarce in North America since Saturn / Opel withdrew.
Saturn Vue(1 issue)
- Vue 3.5L Honda V6 Timing Belt Service Interval2004-2007
2004-2007 Saturn Vue V6 used the Honda 3.5L J35 V6 (sourced from Honda) — same engine as the Honda Pilot/Odyssey/MDX. It uses a timing belt with a recommended replacement interval of 100,000 miles (or 7 years). Interference engine: failure to replace the belt risks catastrophic valve damage. Water pump should be replaced at the same time.

What does P0335 mean on Saturn?▼
P0335 stands for "Crankshaft Position Sensor A Circuit Malfunction."
