Inspection Procedure
WARNING: This page is about a different car, the 2011 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
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 by this diagnostic troubleshooting procedure, troubleshoot the engine mechanical system.
- Check the engine speed. The engine speed can be checked by using Techstream. To check, follow the procedure below:
- Connect Techstream to the DLC3.
- Start the engine.
- Turn the Techstream on.
- Enter the following menus: Powertrain / Engine / Data List / All Data / Engine Speed.
- The engine speed may be indicated as zero despite the engine revolving normally. This is caused by a lack of NE signals from the crankshaft position (CKP) sensor. Alternatively, the engine speed may be indicated as lower than the actual engine speed, if the CKP sensor output voltage is insufficient.
- Read freeze frame data using 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.
