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

WARNING: This page is about a different car, the 1994 Plymouth Sundance, 1994 Plymouth Acclaim, 1994 Dodge Spirit, 1994 Dodge Shadow, and 1994 Chrysler LeBaron. 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  . 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.
