Test NS-6A - Correcting No Response Condition

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. If vehicle starts, go to TEST NS-6B. If vehicle does not start, turn ignition off. Disconnect Throttle Position Sensor (TPS) connector. Turn ignition on. Put DRB in voltmeter mode.
  2. Using DRB, check voltage on TPS connector Violet/White wire. If voltage is more than 6 volts, repair open ground circuits at Powertrain Control Module (PCM) connector terminals No. 5 (Black/White wire), No. 11 (Black/Tan wire) and No. 12 (Black/Tan wire). Perform TEST VER-1  . If voltage is less than 6 volts, go to next step.
  3. If voltage is less than 4.4 volts, go to step 5). If voltage is more than 4.4 volts, reconnect TPS connector. Disconnect Manifold Absolute Pressure (MAP) sensor connector.
  4. Using DRB, check voltage on MAP sensor connector Violet/White wire. If voltage is more than 4.4 volts, go to TEST NS-6B. If voltage is less than 4.4 volts, replace TPS. Perform TEST VER-1.
  5. Disconnect MAP sensor electrical connector. Using DRB, check voltage on TPS connector Violet/White wire. If voltage is more than 4.4 volts, replace MAP sensor. Perform TEST VER-1.
  6. If voltage is less than 4.4 volts, turn ignition off. Disconnect PCM connector. Put DRB in ohmmeter mode. Using DRB, check resistance of PCM connector terminal No. 6 (Violet/White wire).
  7. If resistance is less than 5 ohms, repair short to ground in Violet/White wire. Perform TEST VER-1. If resistance is more than 5 ohms, go to next step.
  8. Using an external ohmmeter, check resistance between PCM connector terminal No. 4 (Black/Light Blue wire) and PCM connector terminal No. 6 (Violet/White wire). If resistance is more than 5 ohms, go to next step. If resistance is less than 5 ohms, repair short to ground in Violet/White wire. Perform TEST VER-1.
  9. Turn ignition on. Put DRB in voltmeter mode. 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 between PCM connector and ignition switch. Perform TEST VER-1  . If voltage is more than 10 volts, go to next step.
  10. Using DRB, check voltage on PCM connector terminal No. 3 (Red/White wire). If voltage is more than 10 volts, replace PCM. Perform TEST VER-1. If voltage is less than 10 volts, go to next step.
  11. On AA, AP bodies, go to TEST NS-6C  . On AJ body, remove fuse No. 3 from Power Distribution Center (PDC). Inspect fuse. If fuse is okay, go to next step. If fuse is blown, go to step 13).
  12. Put DRB in voltmeter mode. Using DRB, check voltage on battery voltage side of PDC fuse socket. If voltage is more than 10 volts, repair open in wire between PDC fuse socket and PCM connector terminal No. 3. Perform TEST VER-1. If voltage is less than 10 volts, repair open in battery voltage side of PDC fuse socket. Perform TEST VER-1.
  13. Turn ignition off. Disconnect ASD relay and fuel pump relay. Put DRB in ohmmeter mode. Using DRB, check resistance of PCM connector terminal No. 3 (Red/White wire). If resistance is less than 5 ohms, repair short to ground in Red/White wire. Perform TEST VER-1.
  14. If resistance is more than 5 ohms, check resistance of ASD relay connector terminal "D" (Dark Green/Orange wire). If resistance is less than 5 ohms, go to next step. If resistance is more than 5 ohms, go to TEST NS-6D  .
  15. Disconnect ignition coil connector. Using DRB, check resistance of ASD relay connector terminal "D" (Dark Green/Orange wire). If resistance is more than 5 ohms, replace ignition coil. Perform TEST VER-1.
  16. If resistance is less than 5 ohms, disconnect generator field connector. Using DRB, check resistance of ASD relay connector terminal "D" (Dark Green/Orange wire). If resistance is more than 5 ohms, repair short to ground in generator. Perform TEST VER-1  .
  17. If resistance is less than 5 ohms, disconnect fuel injector harness connector. Using DRB, check resistance of ASD relay connector terminal "D" (Dark Green/Orange wire). If resistance is more than 5 ohms, repair short to ground in Dark Green/Orange wire. Perform TEST VER-1. If resistance is less than 5 ohms, repair short to ground in Dark Green/Orange wire between ASD relay connector and injector harness. Perform TEST VER-1.
