P0335 on Saturn by model: symptoms, diagnosis and fix
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.
Common Symptoms
- timing belt chirping
- whine from front of engine
- oil leak at front
- service due
How to Fix
Full timing belt + water pump + tensioner + idler service kit ($600-$1,000 at independent). Use OEM Honda or quality aftermarket Gates/Aisin parts. Do NOT exceed the interval — this is an interference design. Some owners replaced at 90,000 miles for extra margin.

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.
Common Symptoms
- coolant weep
- whine from front of engine
- timing chain rattle
- misfire
How to Fix
Replace water pump WITH timing chain kit as preventive service ($1,200-$2,000 at independent specialist). Parts may need to be sourced through Opel/Vauxhall channels (UK, Germany). Catastrophic pump seize means head rebuild ($3,500+). Do not delay if there is any whining or coolant weep from the front of the engine.

Frequently asked questions
What does P0335 mean on a Saturn?
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. 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. On Saturn it is documented across 2 models: Vue, Astra.
What are the most common causes of P0335?
The most common causes of P0335 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P0335 on a Saturn?
Published repair estimates on Saturn range from $600 to $4,000 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.
