Test TC-2A - No Crank Reference Signal At Pcm (DTC 11)

WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 1994 Chrysler New Yorker, 1994 Chrysler LHS, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: For circuit & connector terminal identification, see CONNECTOR IDENTIFICATION DIRECTORY TABLE  . For wiring diagrams, see WIRING DIAGRAMS  section. After each repair, perform TEST VER-2  .
  1. Using DRB, erase trouble codes. Attempt to start engine. If necessary, crank engine for at least 10 seconds. Read trouble codes. If DRB displays NO SIGNAL or CAM ONLY, go to step 5). If DRB does not display NO SIGNAL or CAM ONLY, go to next step.
  2. At this time, the condition required to set trouble code is not present. NO SIGNAL or CAM ONLY trouble code sets if Powertrain Control Module (PCM) does not see crank signal with cam signal present. Possible causes are: open 8-volt power supply at Crankshaft Position (CKP) Sensor, open or shorted CKP sensor signal wire, open CKP sensor ground, failed CKP, improperly adjusted CKP sensor, failed PCM, or failed transmission control module. Go to next step.
  3. Inspect CKP sensor wiring and connectors. Clean and repair wiring and connectors as required. If wiring and connectors are okay, go to next step.
  4. Start engine. Wiggle wiring harness from CKP to PCM. If engine misses or stalls when wiring harness is wiggled, repair wiring harness where wiggling caused problem. If engine does not miss or stall when wiring harness is wiggled, see INACTIVE TROUBLE CODE CONDITION  in this article. Test is complete.
  5. If DRB displays NO SIGNAL or CAM ONLY in step 1), turn ignition off. Disconnect Crankshaft Position (CKP) sensor connector. Using DRB in voltmeter mode, check voltage on CKP sensor connector terminal No. 1 (Orange wire). If voltage is less than 7 volts, go to TEST TC-2B. If voltage is more than 7 volts, go to next step.
  6. Connect one end of a jumper wire to CKP sensor connector terminal No. 3 (Light Blue/Dark Blue wire). Turn ignition on. Using DRB, read DIS signal status. Observe DRB while tapping other end of jumper wire to CKP sensor connector terminal No. 2 (Black/Light Blue wire). If DRB displays CRANK ONLY, replace CKP sensor. If DRB does not display CRANK ONLY, go to next step.
  7. Disconnect jumper wire. Using DRB in ohmmeter mode, check resistance of CKP sensor connector terminal No. 2 (Black/Light Blue wire). If resistance is more than 5 ohms, repair open Black/Light Blue wire. If resistance is less than 5 ohms, go to next step.
  8. Ensure ignition is off. Disconnect Powertrain Control Module (PCM) connector. PCM is located under air cleaner. Inspect PCM connector. Repair any terminals that are damaged, pushed out or miswired. If PCM connector is okay, go to next step.
  9. Using an external ohmmeter, check resistance of Light Blue/Dark Blue wire between CKP sensor connector terminal No. 3 and PCM connector terminal No. 24. If resistance is more than 5 ohms, repair open Light Blue/Dark Blue wire. If resistance is less than 5 ohms, go to next step.
  10. Using DRB in ohmmeter mode, check resistance of PCM connector terminal No. 24 (Light Blue/Dark Blue wire). If resistance is more than 5 ohms, replace PCM. If resistance is less than 5 ohms, go to next step.
  11. Disconnect Transmission Control Module (TCM) connector. TCM is located in engine compartment between left front fender and battery. Check resistance of PCM connector terminal No. 24 (Light Blue/Dark Blue wire). If resistance is more than 5 ohms, replace TCM. If resistance is less than 5 ohms, repair short to ground in Light Blue/Dark Blue wire.
