Was the code P0500? Is the check engine light on or off? If still on recheck the code, reset the KAM (keep alive memory) by removing the negative battery cable for 20-30 minutes. The car may run a bit differently until it relearns it's parameters. If P0500 comes back, the PCM could be the problem, or the wires from the VSS to the PCM.
