The 2009 Chevy Malibu speed sensor can be tracked down on the result shaft from the transmission. This is a sensor that is intended to quantify the rotational speed of the result shaft and afterward send that data to the ECU. From that point the ECU figures it out and can send a last speed perusing to your speedometer to tell you how quick you are driving. In the event that your speed sensor has issues you will typically see a check motor light on at your scramble. Your speedometer may likewise have issues and it could show no speed or off base paces relying upon how the sensor is coming up short. In the event that you want to supplant it,it is as a rule about $100 to change out at a shop.
