Frequently asked questions
What does P0335 mean on a Renault?
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 Renault it is documented across 1 model: Megane.
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.
