Test TC-27B - No Vehicle Speed Sensor Signal
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

section. After each repair, perform TEST VER-2
.
- Using DRB in ohmmeter mode, check resistance of Powertrain Control Module (PCM) connector terminal No. 47 (White/Orange wire). PCM is located under air cleaner. If resistance is more than 5 ohms, go to step 3). If resistance is less than 5 ohms, go to next step.
- Disconnect Speed Proportional Steering (SPS) Module. SPS module is located on end of steering gear. Check resistance of PCM connector terminal No. 47 (White/Orange wire). If resistance is more than 5 ohms, replace SPS module. If resistance is less than 5 ohms, repair short to ground in White/Orange wire.
- If resistance is more than 5 ohms in step 1), use an external ohmmeter to check resistance of White/Orange wire between Powertrain Control Module (PCM) connector terminal No. 47 and Transmission Control Module (TCM) connector terminal No. 58. TCM is located in engine compartment between left front fender and battery. If resistance is more than 5 ohms, repair open White/Orange wire. If resistance is less than 5 ohms, replace PCM.
