What is the meaning of OBD-II code P0335, and what are the possible causes and solutions for this code to be generated?

The P0335 code is triggered when the PCM doesn't detect the proper crankshaft sensor function, resulting in the Check Engine Light appearing and failsafe mode being activated. There are several possible causes for a P0335 code, such as: -Defective wiring in the harness -Inadequate electrical connections -Crankshaft sensor malfunction -Signal plate damage -Timing belt or chain breakage -PCM malfunctioning To diagnose the problem, a mechanic will typically start by using a scan tool to check the PCM for codes. They will review current, history, and pending codes along with freeze frame data. After clearing the codes, they will do a road test and visual inspection of the crankshaft position sensor and wiring. The scan tool will monitor the sensor readings and RPM signal. If in range, the wiring will be tested, and the PCM will be checked under manufacturer guidelines. The resolution to the P0335 code will vary based on the underlying cause. Options may include replacing the crankshaft sensor, repairing or replacing the wiring harness, replacing the PCM, installing a new signal plate, or fixing any mechanical damage caused by the engine timing belt or chain. A crankshaft position sensor measures the speed of the crankshaft in RPM's for the computer to use for fuel mapping and timing. An advanced scan tool is crucial for diagnosing P0335 and allows technicians to monitor the sensor's operation and check engine RPM and camshaft position data to find the fault.
