1999 toyota camry speedometer and mileage not working

@uche4706 your car does not have a speedometer cable. Your Toyota's speedometer is controlled by a Speed Sensor (VSS)that is attached to the top of the bell housing. There is a spindle that matches up with the Flywheel, and there is an electronic pickup that detects how fast the Flywheel is spinning and Sends the signal to the Cluster. If the electronic pickup part of the Speed Sensor is not detecting how fast the Flywheel is spinning, your speedometer will not work. Now if your speedometer is not working, it could be the Vehicle Speed Sensor (VSS) but also the cluster itself (which would be my first choice since a failed VSS or ECM would most likely trigger a "Service engine Light" OBD code) as well as the ECM. You do want to check on this. The instrument cluster comes out with 5 screws. The speedometer assembly comes out with 5 screws. Look under the odometer display for the speedo chip, and right next to it, is the ceramic resonator. You can try to bend the resonator over about 45 degrees. If that doesn’t fix it then buy a new speedometer assembly. If unsure you can always post some good images with your question which will allow us to see what you see. Use this guide 在已经存在的问题里加入图片 for that. Not sure what you mean by the “car movement is bad”. So, we would need more information on that.
