TDC/CKP/CYP Sensor

  1. Unplug TDC/CKP/CYP sensor connector, located at distributor. Measure resistance between terminals "B" and "F". Measure resistance between terminals "C" and "G". See Fig 1 . Measure resistance between terminals "D" and "H". If resistance is 350-700 ohms for each pair, go to next step. If any measurement is not as specified, replace distributor.
  2. Check for continuity between each terminal and chassis ground. If continuity exists at any terminal, replace distributor.
