Vehicle Speed Sensor
WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
On RPO LSJ equipped vehicles, the vehicle speed sensor (VSS) is mounted to a bracket which is in turn mounted to the intermediate drive shaft (IDS) bracket. The IDS bracket is machined to a precise thickness and the VSS bracket is manufactured to a precise thickness to position the VSS with the correct air-gap to the tone wheel on the IDS. The VSS to tone wheel air-gap is non-adjustable.
