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, troubleshoot the engine mechanical systems.
• Check the engine speed. The engine speed can be checked using the Techstream. To check, follow the operation below:
  1. Connect the Techstream to the DLC3.
  2. Start the engine.
  3. Turn the Techstream on.
  4. Enter the following menus: Powertrain / Engine and ECT / Data List / Engine Speed.
  • The engine speed may be indicated as zero despite the engine rotating normally. This is caused by a lack of NE signals from the crankshaft position sensor. Alternatively, the engine speed may be indicated as lower 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 be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
