TDC/Crank Sensor

  1. Disconnect 4-pin connector from TDC/CRANK sensor. Measure resistance between sensor terminals A and B and between terminals C and D. See Fig 1 . If resistance readings are 700-1000 ohms, go to next step. If resistance readings are not as specified, replace pulse generator assembly.
  2. Check for continuity between ground and each terminal. If continuity exists, replace pulse generator assembly.
