DTC NO. DTC DETECTION CONDITION TROUBLE AREA ECM P0368 P0393 (1 trip detection logic) Open or short in VVT sensor (for exhaust Exhaust camshaft Timing chain jumped tooth ECM Reference: Inspection using an oscilloscope Standard: TESTER CONNECTION TOOL SETTING CONDITION SPECIFIED CONDITION D74-110 (NE+) - D74-111 (NE-) 5 V/DIV. 20 msec./DIV. Cranking or idling The correct waveform is as shown D74-69 (EV1+) - D74-68 (EV1-) 5 V/DIV. 20 msec./DIV. Cranking or idling The correct waveform is as shown D74-64 (EV2+) - D74-65 (EV2-) 5 V/DIV. 20 msec./DIV. Cranking or idling The correct waveform is as shown HINT: EV1 and EV2 are the VVT sensor signals, and NE is the CKP sensor signal. MONITOR DESCRIPTION When the sensor output voltage remains at less than 0.3 V, or more than 4.7 V for more than 4 seconds, the ECM stores a DTC.
