Test TC-11A - No Vehicle Speed Sensor Signal (DTC 15)
WARNING: This page is about a different car, the 1995 Dodge Dakota. 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 . For wiring diagrams, see WIRING DIAGRAM section.
- Raise vehicle so drive wheels are free to spin. Start engine. Using scan tool, read Vehicle Speed Sensor (VSS) signal. Put transmission in any forward gear. If scan tool displays more than zero MPH, go to step 2). If scan tool does not display more than zero MPH and vehicle, go to TEST TC-11C.
- Condition required to set DTC is not present at this time. NO VEHICLE SPEED SENSOR SIGNAL DTC sets if Powertrain Control Module (PCM) does not see a VSS signal at PCM terminal No. 47 (White/Orange wire) for more than 11 seconds. Possible causes are: open or shorted VSS White/Orange wire, failed VSS, open VSS Orange wire or Black/Light Blue wire, damaged speedometer pinion, or failed PCM. Go to next step.
- Inspect all related wiring and connectors and repair as necessary. Perform TEST VER-2. If no problems are found with wiring and connectors, see INACTIVE DTC CONDITION .
