Any time I get over about 65mph the speedo will start to jump around. It' doesn't bounce but will drop 5-10 mph hold there for a split second then jump back up. It will just do this back and forth randomly. I've replaced the VSS and with AE hooked up it shows a steady speed which tells me that everything up to the PCM is good.
I've recently got a Lightning speedo thinking it was the speedo that was bad but the new speedo still does it. I had both speedos checked out at Tacoma Speedometer and when they test them they are rock steady. So this tells me it's still something in the truck.
The guy at Tacoma Speedometer said it could be the RABS module but I think that is between the VSS and PCM and if AE is showing steady I wouldn't think that would be it. The only thing I can think of is if I've got a chafed wire or a bad pin in a connector. Anyone else had a similar issue that they found the fix for?
