im stumped on a p0500 code that I posted a thread yesterday. my scan tool will not read any speed while driving down the road. it always says 0mph does this signal come from the ecu or the gem module. I replaced the gem module and wodering if this could be the root of the problem because all else checks out and speedo works. I would imagine the ecu would tell the scan tool but im unsure.
