What Does P0335 Mean?
P0335 indicates a problem with the crankshaft position sensor circuit. This sensor provides critical timing information to the ECM for fuel injection and ignition.No-Start Potential
This is one of the sensors that can cause a complete no-start condition. Without a crank signal, the ECM doesn't know the engine position.Heat Sensitivity
Crank sensors often fail when hot and work again when cooled. If your car won't restart when hot but starts fine cold, suspect this sensor.Related Codes
