P0335 on Citroen by model: symptoms, diagnosis and fix
PSA/Stellantis PureTech 1.2 (EB2) engines run an oil-immersed ("wet") timing belt instead of a chain. The belt's outer rubber layer can delaminate and shed particles into the oil pickup, clogging the strainer and starving the engine of oil. Stellantis revised the belt material and shortened the service interval (now 60,000 mi or 6 years, whichever first) but earlier-spec belts still in service are at risk.
Common Symptoms
- Rattling on cold start
- Engine warning light
- Misfires
- Power loss
How to Fix
Replace the timing chain, tensioner, and sprockets with revised parts. Check eligibility for PSA extended warranty (10 years/200,000km). Use only manufacturer-specified oil.

Frequently asked questions
What does P0335 mean on a Citroen?
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 Citroen it is documented across 1 model: C3.
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 Citroen?
Published repair estimates on Citroen range from $800 to $2,000 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.
