31 vehicles · 17 makes · $40-$5,000 repair
Most Reported On
P0335 is an OBD-II diagnostic trouble code meaning “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. This code is most commonly reported on 2010-2018 Mercedes-Benz E-Class (E350, E400, E550), 2005-2013 Land Rover Range Rover Sport, and 2012-2018 Mercedes-Benz CLS-Class (CLS400, CLS550), plus 28 other vehicles, with repair costs ranging from $40 to $5,000.
