Customer Concern: No start condition with trouble code P0335 present. Customer said it started to sputter and then would not start after they shut it off. Tests/Procedures: 1. Check the hall effect sensor while cranking on the Yellow/Green wire. A 5 volt square wave is normal. This signal should be consistent and clean. Also verify the Black wire has a good ground and the Brown wire has battery voltage at the crankshaft position sensor. 2. There is a plate in the front of the engine that triggers the crankshaft sensor, verify the timing belt or some debris has not bent or damaged the sensor plate. Potential Causes: Crankshaft Position (CKP) Sensor Wiring
