Last night
Driving at 70 mph through hills on cruise control I got a thunk and dropped out of CC, also flashing wrench on the dash for a moment. Manual throttle did not feel right but I could keep going. I noticed when I let off the throttle engine braking was much stronger than usual. Later tried CC again and it would not function. I only came to 1 stop and shifting through the first few gears was not normal. Reminded me of how an RC transmission works if you are familiar with gas RC vehicles.About 30 minutes freeway and 15 city.Not hard to get it home but it was a little nerve-racking, I was thinking I had a transmission issue.
This morning
I hooked up a code reader, something worth having at home for $40, and got P2135(TPS sensor, etc). I then searched here and read through a few threads prior to starting work on the vehicle .
I tested the throttle and pedal first. With the car on (engine not running) and intake tube removed (so you can see the throttle plate) I pressed the pedal and had someone stand in front of the vehicle watching the throttle plate move. Everything was as it should be. After that I tested the TPS.
