What causes a DTC on a VSS sensor?
VSS range and performance DTCs could be related to circuit or sensor faults, as well as faults in the mechanical system to which is it connected. Circuit Check – Check first the circuit between the ECM and VSS. There should be 0 Ω resistance between the ECM and VSS, and >10 kΩ to power or ground.
What is the trouble code on the VSS?
The trouble code that will come back, should by what you have stated the symptoms are, be a code with these letters and numbers in it to identify the trouble area. P0500 or P0501. This is the VSS (vehicle speed sensor) circuit. If the n…
How to check VSS code on reed switch sensor?
If the VSS checks out OK, but you still have P0500 code illuminated, you’ll need to check the sensor circuit. Reed switch sensor: A reed switch VSS circuit is pretty simple. The sensor will have two wires going to it: power and the return signal to the PCM.
How to check the VSS provider ( VSS ) status?

How to check the VSS subsystem ( 117665 )?
VSS produces consistent shadow copies by coordinating Replay with applications, Exchange, SQL, file-system services. Before installing Replay or AppAssure Agents on the application servers, it is necessary to verify that the latest Windows service packs and the latest VSS updates are installed. Here are some simple steps to check the VSS subsystem.
How is the VSS sensor used in the PCM?
OPERATION The Vehicle Speed (VSS) Sensor input is used by the PCM to determine vehicle speed. The VSS generates a signal that increases in frequency proportionate to vehicle speed. The PCM has a base frequency stored in memory for a distance of one mile.
