Test NTC-11A - Checking Pcm Ground & Power Circuits

WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION DIRECTORY . For wiring diagrams, see WIRING DIAGRAMS  section. After each repair, perform TEST VER-2 .
  1. Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. PCM is located under air cleaner. Using DRB in ohmmeter mode, check resistance of PCM connector terminal No. 5 (Black/White wire). If resistance is more than 5 ohms, repair open in Black/White wire. If resistance is less than 5 ohms, go to next step.
  2. Using DRB, check resistance of PCM connector terminal No. 11 (Black/Tan wire). If resistance is more than 5 ohms, repair open in Black/Tan wire. If resistance is less than 5 ohms, go to next step.
  3. Using DRB, check resistance of PCM connector terminal No. 12 (Black/Tan wire). If resistance is more than 5 ohms, repair open in Black/Tan wire. If resistance is less than 5 ohms, go to next step.
  4. Turn ignition on. Using DRB in voltmeter mode, check voltage on PCM connector terminal No. 9 (Dark Blue/White wire). If voltage is less than 10 volts, repair open Dark Blue/White wire. If voltage is more than 10 volts, turn ignition off. Reconnect PCM connector. PCM ground and power circuits are okay. Test is complete.
