P0335 on Renault
Crankshaft Position Sensor A Circuit Malfunction
P0335 on Renault vehicles indicates crankshaft position sensor a circuit malfunction. Au7o has documented this code across 1 Renault model — most commonly on Megane. 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 Renault range from $100 to $500, 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 Renault by Model
Renault Megane(1 issue)
- Injection System Fault Warning2003-2023
The Megane displays an "Injection Fault" warning on the dashboard, which can be triggered by numerous sensors and components. Common causes include the crankshaft position sensor, throttle body, and fuel pressure regulator.
