The speedometer stopped working and the check engine light came on. At the next stop light the light went out and the speedometer began working again. I searched but could not find the speedometer cable to tighten the connections. Does anyone know where to find the cable or is there another problem developing?
As i unserdtand it, there is no speedometer cable, per-say, there is a speed sensor in the wheel hub assembly, this sends a signal to the ECM. Which then sends the speed to the BCM, then to the cluster over a class 2 link. Take it to saturn or advanced to hve them read the error code from the ecm.
It sounds like the VSS, vehicle speed sensor, is the problem. You need to check if there are any codes stored. If a code 24 is stored, then I would replace the sensor or double check the connection and wiring. It is located in the transaxle down low. The VSS gives the PCM info on how fast you are moving which in turn sends the speedo the same info.
