So my daughters got a 04 Cavalier, this site has been a great help learning the ecotech engine. Had a question on the speedometer, been acting up (drifts, won't re-zero when engine turned off). Anyone know where the speed sensor is located for the speedometer on the 2.2? From what I've been reading, usually not the sensor, usually the problem is the cluster inthe cab of the car.
I believe the VSS sensor is at the output shaft on the transaxle.
