Inspection Procedure

HINT: 

• After performing the inspection procedure for the crankshaft position sensor, if DTC P0335 is output again, check the following items related to the camshaft position sensor.
  • Installation condition of the camshaft position sensor
  • Installation condition of the camshaft
  • Connection of the camshaft position sensor connector
• If no problem is found through this diagnostic troubleshooting procedure, there may be a mechanical problem with the engine.
• Check the engine speed. The engine speed can be checked by using the Techstream. To check, follow the procedure below:
  1. Connect the Techstream to the DLC3.
  2. Start the engine.
  3. Turn the Techstream on.
  4. Enter the following menus: Powertrain / Engine / Data List / All Data / Engine Speed.
  • The engine speed may be indicated as zero despite the crankshaft revolving normally. This is caused by a lack of NE signals from the crankshaft position sensor. Alternatively, the engine speed may be indicated as less than the actual engine speed if the crankshaft position sensor output voltage is insufficient.
• Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
