Big Hand Syndrome. I wondered if any of my Classic owning friends would ever experience this. Yesterday, it happened. The accelerator-pedal became sluggish, making the car feel as though it was fighting an invisible resistance in front... as if a big hand was pushing against it, hence the name. It was pretty darn obvious what had occurred too. The dashboard and Multi-Display both lit up like Christmas trees. A bunch of warnings made it quite clear. Fortunately, taking the car to the dealer was no big deal. Owners have reported long spans between failures like that, so just driving there was a non-event. All went fine. And once there, they pulled 4 codes from the computer: P0300,
P3101, C1259. It was a dead giveaway that TSB EG011-03 should be performed. It's a special service for this very situation, something unique to the older design (THS). The required ECU replacement was done without any trouble... and the owner wasn't charged for anything! Now that 2002 Prius is happy again.
