Vehicle speed sensor DTC
Is anyone else getting this code via Evoscan? I don't have a CEL, but it shows up under the codes when I use EvoScan to pull them. Clearing it results in it coming back on immediatley. Is it just a glitch?

Not sure if its a real code or not.. I see it on my car with Evoscan, but it doesnt turn up in the snapshots with my other scanner.. What is interesting is I did notice that the vehicle speed sensor does drop out periodically... never noticed it before until I got logging fast enough to capture it.. (the ECU+ logs vehicle speed and drops out occasionally)

I have the same issue. EVOScan frequently shows the following codes:
VSS
knock sensor
barometric pressure sensor
fuel injector circuit
I am 99% sure these are false codes. I have no MIL and the car runs fine. I think it's a bug in EVOSCAN.

I was getting Barometric Pressure and Vehicle Speed codes too. I then kept re-checking serveral times over a minute or two (w/out clearing them) and the Barometric Pressure one dropped off the list but Veh Speed stayed. A few more clicks and Veh Speed dropped off too (no codes remaining). Checked again and Veh Speed came back. This was all while idling in my driveway, btw. I say it's a glitch in EVOscan.

same thing here, although I couldn't get it to clear with evoscan. Had to use my other datalogger to clear it.

100-76=24, 24/4=6%. Higher than 100 means the computer is having to add fuel so the car is lean. Lower than 100 means the car is removing fuel so it is rich. I have verified this using a MAC scan tool.
