Answer

Hello and thank you for choosing Just Answer.

If you are getting faulty speed readings or the gauge is acting "erratic", this is usually due to a bad speed sensor. The speed sensor is a magnetic type sensor which is located on the transmission. The speed sensor sends a signal to the PCM which give the gauge reading. If the sensor is bad your speed reading will be off.

Reply to OnlineMechanic's Post: Is this just for an automatic? I have a manual gearbox - the Haynes workshop manual I have only gives details of the speed sensor for automatics.

Accepted Answer

The car still has a speed sensor. Something has to send the reading to the gauge, which is the speed sensor.
