Diagnostic Aids
DTC P0335 uses two-trip detection logic. Using Toyota hand-held tester or scan tool, read FREEZE FRAME data. Freeze frame data records engine conditions when malfunction is detected.
If oscilloscope is available, crankshaft position sensor operation may be checked by reading crankshaft position sensor waveform pattern with engine idling. This may be done by monitoring the crankshaft position sensor signal which may be referred to as the NE signal. Crankshaft position sensor waveform pattern may be checked by connecting oscilloscope between terminals No. 16 (Black/White wire) and No. 24 (White wire) at ECM electrical connector E11. This is the NE+ and NE- terminals on ECM. ECM is located at passenger's side of instrument panel, just below glove box. See Figure. For ECM electrical connector terminal identification, see Figure. Crankshaft position sensor waveform pattern should be properly displayed. See Figure.
