Actually, no there isn't. That'* an ISS. Input Shaft Sensor. The VSS is the one on the diff cover and the codes in question, (I just googled them) and they both are in regards to the Vehicle Speed Sensor.

If I were trying to diagnose this issue, I'd take a ring out the two or three wires, check how the circuit works and go from there. I don't have access to the FSM'* from my current location, but that'* the diagnosis I'd take. As well as reading the diagnostic aids included with the FSM page.

Never seen a bad PCM here on a GXP yet, The only thing I can add is to smear some no-Ox compound on the plug ends, make sure it connects good before you dig further.

FSM is factory service manual. You need to test the wires between both ends. If you have a multi meter set it to continuity, that will beep if the circuit is good. If no beep, the wire is broken.

well guys, i took it to the shop to have them find the problem, and they are saying the sensor, and wire are good, but the signal from the sensor is ok until they test the voltage frome the sensor at higher speeds. they're getting the right voltage by hand turning the wheels, but the voltage isn't moving or something when it goes faster. heard anything like that happen before?
