STEP 1. Using scan tool (M.U.T.-IIISE), check data list item 2: Crankshaft Position Sensor.
STEP 2. Using the oscilloscope, check the crankshaft position sensor.
STEP 3. Measure the sensor supply voltage at crankshaft position sensor harness side connector.
(1) Disconnect the crankshaft position sensor connector and measure at the harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal SGT line and ground.- Voltage should be between 4.9 and 5.1 volts.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Is the measured voltage between 4.9 and 5.1 volts?
Go to Step 5. Go to Step 4.
STEP 4. Check of short to ground and open circuit in SGT line between crankshaft position sensor connector and ECM connector.
STEP 5. Measure the power supply voltage at crankshaft position sensor harness side connector.
(1) Disconnect the crankshaft position sensor connector and measure at the harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal 5V line and ground.- Voltage should be battery positive voltage.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Is battery positive voltage (approximately 12 volts) present?
Go to Step 7. Go to Step 6.
STEP 6. Check of short to ground and open circuit in 5V line between crankshaft position sensor connector and ECM connector.
STEP 7. Check the continuity at crankshaft position sensor harness side connector.
STEP 8. Check of open circuit and harness damage in DGND line between crankshaft position sensor connector and ECM connector.
STEP 9. Check of harness damage in 5V line between ECM connector and crankshaft position sensor connector.
STEP 10. Check of harness damage in SGT line between ECM connector and crankshaft position sensor connector.
STEP 11. Check the crankshaft position sensing ring.
STEP 12. Using scan tool (M.U.T.-IIISE), check data list item 2: Crankshaft Position Sensor.
STEP 13. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 1 . (2) Check the diagnostic trouble code (DTC).
Is DTC P0335 set?
Retry the troubleshooting. The inspection is complete.
