P0335 on Citroen
Crankshaft Position Sensor A Circuit Malfunction
P0335 on Citroen vehicles indicates crankshaft position sensor a circuit malfunction. Au7o has documented this code across 1 Citroen model — most commonly on C3. 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 Citroen range from $800 to $2,000, 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)

- PureTech 1.2 Wet Timing Belt Delamination2014-2026
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.

What does P0335 mean on 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 specifically, this code is documented across 1 model.
What causes P0335 on Citroen vehicles?▼
