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

WARNING: This page is about a different car, the 1994 Plymouth Acclaim and 1994 Dodge Spirit. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: For circuit and connector terminal identification, see CONNECTOR IDENTIFICATION DIRECTORY TABLE  . For wiring diagrams, see WIRING DIAGRAMS  .
  1. Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Put DRB in ohmmeter mode. Using DRB, check resistance of PCM connector terminal No. 5 (Black/White wire). If resistance is more than 5 ohms, repair open in Black/White wire. Perform TEST VER-2. 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. Perform TEST VER-2  . 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. Perform TEST VER-2. If resistance is less than 5 ohms, go to next step.
  4. Put DRB in voltmeter mode. Turn ignition on. Using DRB, check voltage on PCM connector terminal No. 9 (Dark Blue wire). If voltage is less than 10 volts, repair open in Dark Blue wire. Perform TEST VER-2. If voltage is more than 10 volts, turn ignition off. Reconnect PCM connector. PCM grounds and power circuits are okay. Test is complete.
